• Perl script and out of memory errors

  - by Kevin

  We have a midsized server with 48GB of RAM and are attempting to import a list of around 100,000 opt-in email subscribers to a new list management system written in Perl. From my understanding, Perl doesn't have imposed memory limits like PHP, and yet we are continuously getting internal server errors when attempting to do the import. When investigating the error logs, we see that the script ran out of memory. Since perl doesn't have a setting to limit the memory usage (as far as I can tell) why are we getting these errors? I doubt a small import like this is consuming 48GB of ram. We have compromised and split the list into chunks of 10,000, but would like to figure out the root cause for future fixes. This is a CentOS machine with Litespeed as the web server.

• Classic ASP on large memory server

  - by Steve Evans

  I have a client with a large ASP app that apparently is fairly memory intensive. I’m helping them migrate to new hardware they have running Win2k8 R2. They have 4 physical servers with 32gb of RAM each. I’m making the assumption that ASP apps run as a x32 process. So I see that we have two options: On the application pool enable web gardens. Use the physical servers as VM hosts and split the box into say 4 web servers each. Any thoughts on which path will provide us better performance? I’m just not really sure how ASP will handle a machine with lots of memory, and I’m worried it won’t really be able to address the memory well. (you can ignore all the obvious stuff like increased maintenance of 16 web servers vs 4, or the flexibility virtualization gets us over physical servers, etc)

• Plesk on Windows Server 2008 memory usage

  - by Thomas

  I have a server running IIS and Plesk. There is a problem every day now in which the memory usage of PleskControlPanel.exe and w3wp.exe slowly increases. And at some point all of the sites hosted on the server go down. Restarting Plesk through its panel will reset its memory usage for a while, and restarting IIS will make it last even longer, but there is still the constant memory climbing problem. I cannot see anything by looking through the event viewer. Has anyone ever seen anything like this with Plesk on Windows? Thanks for any help.

• SQL Server not releasing Memory

  - by noob2487

  I am using SQL Server 2005. I am running a job which processes around 100 K records. Job runs fine, it takes are 45 mins to execute, which is good. But after that job is processed, I can see instance of SQL Server 2005 still there with around 900 MB of Memory. I waited for around 2 hrs but that memory was not released. Is there any process which takes care of memory here, something like GC (unpredictable) Or am I doing something wrong???

• Modifying kernel shared memory settings on a lion install

  - by andrewjl

  What's the location of the sysctl.conf file on lion? In Snow Leopard it was in /etc/sysctl.conf but now that folder doesn't contain it anymore. Searching for the file in spotlight yields no results. Have the shared memory settings been moved to a different conf file? What is it's name? EDIT I am trying to modify the kernel shared memory settings of the machine. When I didn't find the sysctl.conf file in the right place, I created my own with the recommended settings and put into /etc directory. However running sysctl -a still shows me that the old memory settings are in place. How do I go about modifying these on a lion install?

• Media center consumes all available memory when attempting to play music off of a server

  - by RCIX

  I have Windows 7 Ultimate, and recently, when i try to play a song off of my Twonky Media Server/Windows Media Connect (based on an HP WHS with an Atom), it plays choppily. When i open Resource Monitor, it shows that after ordering the music to play, memory usage rapidly spikes to consume most, if not all, of the available memory on my system (excluding a couple hundred megabytes in standby). Why does it do this and is there anything i can do to stop it? Edit: it happens when I attempt to browse the server's music, not just when i play music. Edit 2: the "ehshell" process is what consumes the memory, appears to me something specific to media center. Moreover, the ehshell process doesn't die in this case. Edit 3: It only happens when browsing my Twonky library, and not my Windows Media Connect.

• Maximum memory allocation for 32bit linux kernel

  - by LedZeppelin

  I was reading this article that talks about how maximum amount of ram dedicated for kernel usage in 32 bit windows is 2GB even when the total amount of ram is 4GB. http://www.brianmadden.com/blogs/brianmadden/archive/2004/02/19/the-4gb-windows-memory-limit-what-does-it-really-mean.aspx\ Is this the same for 32bit linux environments like 32-bit ubuntu 10.04? IE is the max kernel allocation 2GB ram even if the total main memory 4GB? If you increase the total amount of memory to 64GB of ram by recompiling the kernel with the PAE option enabled, what is the maximum amount of ram you can dedicate for kernel usage? Is it still 2GB? Or can you increase it?

• Tuning MySQL to consume less memory

  - by Alex

  I have a VM which has 2GB Ram, (full specs) And I am setting up a site which has one table in particular with over a million records. There's little or no usage of this particular database (perhaps once or twice a day) but simply running mysql grinds the whole server to a halt. I've looked through the top results but nothing is really denting the CPU however the memory seems to be the issue. The site isnt even live of taking requests yet. the memory situation looks like this: # free -m total used free shared buffers cached Mem: 2006 1880 126 0 3 53 -/+ buffers/cache: 1823 183 Swap: 2047 345 1702 Are there any good pointers to tune mysql to stop hogging the system memory? Thanks very much EDIT: (requested by 8bit): http://tny.cz/b41a0b12

• innodb memory usage mysql

  - by Tiddo

  I have a small vps, with only 256mb of ram, with maximum burst up to 512mb. When I configure my vps without innodb, it only uses 130 mb of ram, so that is no problem for me. But when I turn on innodb, The memory usage grows to about 300-400 mb. Is it possible to run innodb such that I won't exceed the 256mb? preferably I don't want to use more than 100mb for innodb. I already came across some sites which said I could limit the memory usage, but if I limit it to only 100mb will the db run well enough? (compared to for example the MyISAM storage engine) If 100mb is to little memory for innodb, can you recommend me any other storage engine which supports transactions?

• Asus P6X58-E WS motherboard memory limits

  - by Arsen Zahray

  I've just ordered motherboard Asus P6X58-E WS, and now I'm, looking for memory for it. It has 6 slots, but the strange thing is, that in specifications it says that it is limited to 24G of memory . I'm planning on using 8G Kingston KVR1333D3D4R9S/8G sticks with it. Using those sticks, I'll be teoretically limited to 48G. Does the 24G limitation mean, that even if I install all 6 sticks, I still will be limited by 24G of possible memory? Sorry if the question seems dumb, but I never faced such a limitation before

• Dropping Cached Memory on FreeBSD

  - by user1066698

  i use FreeNAS server which is built on OS version FreeBSD 8.2-RELEASE-p6. I use ZFS file system with 13TB HDD on my 8GB physical ram installed box. It almost uses all of RAM installed while proccessing some request. However, it still uses same amount of memory on idle times. So this is becoming a problem sometimes. On my centos web server; i use following command to drop cached memory with a cronjob; sync; echo 3 > /proc/sys/vm/drop_caches However, this command does not work on my Freenas server. How can i drop cached memory on my FreeNAS box which is built on FreeBSD 8.2 Thank you

• SmartGWT TreeGrid, adding and editing

  - by Banang

  I'm trying to programmatically add a new TreeNode to a TreeGrid, and then turn on editing for the newly added node. This is my data source: DataSource ds = new DataSource(); DataSourceTextField idField = new DataSourceTextField("key", "Id"); DataSourceTextField nameField = new DataSourceTextField("name", "Name"); DataSourceTextField keyField = new DataSourceTextField("id", "Key"); keyField.setPrimaryKey(true); ds.setFields(idField, keyField, nameField); ds.setClientOnly(true); My fields: TreeGridField name = new TreeGridField("name", "Name"); TreeGridField id = new TreeGridField("id", "Id"); TreeGridField key = new TreeGridField("key", "Key"); key.setHidden(true); id.setHidden(true); And my code for adding a new record: TreeNode parent = (TreeNode) treeGrid.getSelectedRecord(); if (parent == null) parent = treeGrid.getData().getRoot(); Tree data = treeGrid.getData(); node = data.add(node, parent); Now, how on earth do I switch on editing for the added node? I've tried startEditing(), but that defaults to the first node, and I don't see any way of obtaining the row number for the newly added node, which would allow me to use startEditing(rowNum, colNum, suppressFocus). Using startEditNew() is not an option for many reasons, mainly because that method adds the new node to the bottom of the tree, which doesn't work at all with my app. How do I do this? Grateful for any help you guys can give me.

• Memory leak when using Workflow 4.0 SqlWorkflowInstanceStore and PersistableIdleAction.Unload

  - by Rohland

  Hi, This particular problem is driving me nuts. I wonder if anyone has experienced a similar problem. If I load up a workflow then unload it and perform a memory snapshot then the result is predictable - my workflow is no longer in memory. However, if I load up a workflow and set the PersistableIdle action to PersistableIdleAction.Unload and let the workflow idle the workflow remains in memory even though the Unload action fires. I used ANTS Memory Profiler to debug this issue. This is the object retention graph outputted showing that an internal object is hanging onto my workflow instance. Can anyone else verify this problem? My code amounts to the following: Create SqlWorkflowInstanceStore and setup lock owner handle -- At this point I take a memory snapshot Create an instance of Workflow1 Set the PersistableIdle action Apply the instancestore to Workflow1 Setup action event handlers for Idle, Unload, UnhandledException etc. Persist the workflow instance Run the workflow instance Wait for instance to idle (caused by Delay activity) Ensure the Unload action is fired -- At this point I take a second memory snapshot From the above image, it is clear that the only object referencing Workflow1 is some internal event handlers result which I have no ability to dispose of. Any clues?

• Scheme - Memory System

  - by Eric

  I am trying to make a memory system where you input something in a slot of memory. So what I am doing is making an Alist and the car of the pairs is the memory location and the cdr is the val. I need the program to understand two messages, Read and Write. Read just displaying the memory location selected and the val that is assigned to that location and write changes the val of the location or address. How do I make my code so it reads the location you want it to and write to the location you want it to? Feel free to test this yourself. Any help would be much appreciated. This is what I have: (define make-memory (lambda (n) (letrec ((mem '()) (dump (display mem))) (lambda () (if (= n 0) (cons (cons n 0) mem) mem) (cons (cons (- n 1) 0) mem)) (lambda (msg loc val) (cond ((equal? msg 'read) (display (cons n val))(set! n (- n 1))) ((equal? msg 'write) (set! mem (cons val loc)) (set! n (- n 1)) (display mem))))))) (define mymem (make-memory 100))

• Editing list properties using DataGridview

  - by toom

  Ok, I have my custom class: public class FileItem : INotifyPropertyChanged { int id=0; string value=""; public int Id { get { return id; } set { id = value; Changed("Id"); } } public string Value { get { return value; } set { this.value = value; Changed("Value"); } } public event PropertyChangedEventHandler PropertyChanged; void Changed(string name) { if (PropertyChanged != null) PropertyChanged(this, new PropertyChangedEventArgs(name)); } } public BindingList<FileItem> FilesystemEntries = new BindingList<FileItem>(); And I have DatagridView1 with DataSource set to FilesystemEntries: binding.DataSource = FilesystemEntries; Already I can Add and remove rows - these chnages are reflected on collection. However, Value and Id are not saved into bidning list when i change them in DataGridView, id is always 0 and value is "". How can I make this work? Do I need to implement some interface to FileItem to allow editing properties? ReadOnly of DGV is set to false, same to all columns. Editing, Deleting and Changing are enabled.

• MS Office Excel Ribbon - Cannot change/hide Editing group in Home tab

  - by A9S6

  I have a .net addin for Excel. The addin creates the Ribbon UI for Excel 2007 and re-purposes some existing commands such as Cut, Copy, Paste, Sort etc. For Cut, Copy and Paste I am just overriding their OnAction value to call my own procedure when the buttons are clicked. But for Sort, Sort Asc and Sort Desc commands the case is a little different. When either of the Sort, Sort Asc or Sort Desc buttons are clicked, I want to get notified and then call the default functionality. This was possible in Excel 2003 commandsbars by calling the Execute() method on the CommandBarControl. In Excel 2007, there is a ExecuteMso() method to programmatically click a ribbon element but when the OnAction is overridden, this ExecuteMso() method just executes my own procedure and not the default functionality of that button. So I thought that I will HIDE the Sort buttons in the "Editing" group in Home tab and add my own Sort, Sort Asc and Sort Desc buttons to it. The buttons will call into my procedure first from where I will call the default behavior. Now the problem is that I am unable to change/hide the Editing group (idMso="GroupEditing"). Is this built-in group not editable? I can however HIDE the Clipboard and other groups(but can't add buttons to them). <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui"> <ribbon> <tabs> <tab idMso="TabHome"> <group idMso="GroupEditing" visible="false" /> </tab> </tabs> </ribbon> </customUI>

• Using CGContextDrawTiledImage at different zooms causes massive memory growth

  - by Jacques

  I'm working on app an where there's a view in a zoomable UIScrollView. When the user zooms in or out, I redraw the view that's in the UIScrollView to be nice and sharp. That view has a background image that I draw with CGContextDrawTiledImage. I noticed that memory usage grows every time I switch to a new zoom level. It looks like CGContextDrawTiledImage keeps a cache somewhere of the image scaled to different sizes. So, If I go from 1.0 to 1.1x zoom, memory use grows. Going back to 1.0 doesn't cause it to grow, but then going to 1.05 and then 1.2 causes it to grow twice. Back to 1.1 and no growth. Of course, the zoom level is under user control so I don't have control over how many zoom levels happen. Right now my background image is kind of massive (512x512), so this causes memory usage to grow very quickly. It doesn't show up as a memory leak in Instruments, just additional allocations that never get freed. I've tried to find a way to free the cache that appears to be being created, but no luck. It doesn't seem to respond to low memory warnings, for example. I also tried setting the view's backgroundColor to a UIColor created with colorWithPatternImage, but that doesn't work because I'm doing the scaling by changing the graphics context's CTM, not by setting the view's transform. Any ideas on how to keep memory usage from blowing up?

• What does an object look like in memory?

  - by NeilMonday

  This is probably a really dumb question, but I will ask anyway. I am curious what an object looks like in memory. Obviously it would have to have all of its member data in it. I assume that functions for an object would not be duplicated in memory (or maybe I am wrong?). It would seem wasteful to have 999 objects in memory all with the same function defined over and over. If there is only 1 function in memory for all 999 objects, then how does each function know who's member data to modify (I specifically want to know at the low level). Is there an object pointer that gets sent to the function behind the scenes? Perhaps it is different for every compiler? Also, how does the static keyword affect this? With static member data, I would think that all 999 objects would use the exact same memory location for their static member data. Where does this get stored? Static functions I guess would also just be one place in memory, and would not have to interact with instantiated objects, which I think I understand.

• Reload a UITable on the fly when editing a UITextField inside one of the cells

  - by Saze

  I have a UITable containing some customs UITableCells. Those cells contain a few UILabels and a UITextField. The datasource of the table comes from a main controller's property. (This controller is also the delegate and the dataSource for the table). Here's a simplified screenshot of the UI: Now, I need to update "on the fly" the content of all the UILabels when the user edits one of the UITextFields. To do so, at the I am listening to the "Editing Changed" event at the UITextField level. This triggers the following action: - (IBAction) editChangeHandler: (id) sender { MyAppDelegate *delegate = [[UIApplication sharedApplication] delegate]; [[delegate.viewController.myDataSourceArray objectAtIndex:self.rowIndex] setANumber: [theTextField.text intValue]]; [delegate.viewController reloadRows]; } The reloadRows method in the viewController is as such: - (void) reloadRows { NSLog(@"called reloadRows"); //perform some calculations on the data source objects here... [theUITable reloadData]; } My problem here is that whenever the user changes the value in the field, the reloadRows method is successfully called, so is apparently the reloadData but it also causes the keyboard to be dismissed. So in the end, the user can only touch one key when editing the TextField before the keyboard is dismissed and the table reloaded. Does anybody knows a solution to this or have experienced the same issue?

• Why is my Internet connection randomly dropping?

  - by Jeanno

  Ever since I have installed 12.04 (clean install not an upgrade), i have been having a drop in the Internet connection. The drop in the connection can be anything from 15 seconds to about 3 mins, and then the connection comes back. This behaviour happens while I am actively browsing the Internet, or if I wake up the computer and open Firefox (sometimes I have connection and sometimes I don't) . Please note that when the internet connection is on, it is not slow (as speedtest.net results show) In the beginning, I thought it was a problem with the driver r8169 for my RTL8111/8168B Ethernet card, so I downloaded the r8168 from Realtek website, followed the detailed instructions (blacklisted r8169, changed the file to '.bsh' ...), but still the same problem persisted. So I switched to a wireless connection, and I got the same problem with internet connection dropping randomly. Any ideas?

• How to expose game data in the game without a singelton?

  - by zardon

  I'm quite new to cocos2d and games programming, and am currently I am writing a game that is currently in Prototype stage. Everything is going okay, but I've realized a potentially big problem and I am not sure how to solve it. I am using a singelton to store a bunch of arrays for everything, a global list of planets, a global list of troops, a global list of products, etc. And only now I'm realizing that all of this will be in memory and this is the wrong way to do it. I am not storing files or anything on the disk just yet, with exception to a save/load state, which is a capture of everything. My game makes use of a map which allows you to select a planet, then it will give you a breakdown of that planets troops and resources, Lets use this scenario: My game has 20 planets. On which you can have 20 troops. Straight away that's an array of 400! This does not add the NPC, which is another 10. So, 20x10 = 200 So, now we have 600 all in arrays inside a Singelton. This is obviously very bad, and very wrong. Especially as the game scales in the amount of data. But I need to expose pretty much everything, especially on the map page, and I am not sure how else to do it. I've been told that I can use a controller for the map page which has the information I need for each planet, and other controllers for other items I require global display for. I've also thought about storing each planet's data in a save file, using initWithCoder however there could be a boatload of files on the user's device? I really don't want to use a database, mainly because I would need to translate NSObjects and non-NSObjects like CGRects and CGPoints and Colors into/from SQL. I am open to other ideas on how to store and read game data to prevent using a singelton to store everything, everywhere. Thanks for your time.

• Multiple sites with the same codebase in Python

  - by Jimmy

  I am trying to run a large amount of sites which share about 90% of their code. They are simply designed to query an API and return the results. They will have a common userbase / database but will be configured slightly different and will have different CSS (perhaps even different templating). My initial idea was to run them as separate applications with a common library but I have read about the sites framework which would allow them to run from a single instance of Django which may help to reduce memory usage. https://docs.djangoproject.com/en/dev/ref/contrib/sites/ Is the site framework the right approach to a problem like this, and does it have real benefits over running separate applications? Initially I thought it was, but now I think otherwise. I have heard the following: Your SITE_ID is set in settings.py, so in order to have multiple sites, you need multiple settings.py configurations, which means multiple distinct processes/instances. You can of course share the code base between them, but each site will need a dedicated worker / WSGIDaemon to serve the site. This effectively removes any benefit of running multiple sites under one hood, if each site needs a UWSGI instance running. Alternative ideas of systems: https://github.com/iivvoo/django_layers https://github.com/shestera/django-multisite I don't know what route to be taking with this.

• Problems with Maverick upgrade

  - by altenuta

  I upgraded to Maverick 10.10 from Lucid. I have an old Toshiba Satellite with a 1.1 MHz and 256MB RAM. Initially I couldn't get my wireless to work. That solved itself after installing various updates and programs. The problems that remain are: I have to authorize at least 2 times at start-up. This machine is Ubuntu only. No boot load screen. I have a ton of programs and system directories that are in my home folder. Is this normal? It is difficult to wake the computer from sleep. Usually I just shut it down and restart. Tonight I waited and got a message about corrupt memory. The computer takes forever to do just about everything. Slow to start programs or doing things on the web. I am a longtime Mac user (since 1986). I also manage a network of several windoze machines. I am definitely a GUI guy and do very little in the terminal so I really need to know where to begin to get things straightened out. Can I rescue this machine without wiping it and doing a fresh install? This is basically a hobby machine. Aside from all the programs and upgrades I've installed, I have almost no files or documents to worry about saving. Anyone have any ideas about the problems I'm having and the best way to proceed? Thanks, Al
