  • UseConcMarkSweepGC verbose gc output shows memory drops

    - by user1864747
    I have an application for which I have enabled GC logging. The heap appears to grow then takes a sudden drop, but does not log a Full GC. If there some startup parameter that I can enable that will show me what GC event is reducing the heap size? My environment: Linux 64-Bit, java 1.6.0_31, Java HotSpot(TM) 64-Bit Server VM (build 20.6-b01, mixed mode) VM args: -server -Xms2560m -Xmx2560m -XX:+UseConcMarkSweepGC -XX:MaxPermSize=256m -XX:-PrintGC -XX: -PrintGCDetails -XX:-PrintGCTimeStamps -Xloggc:/xxxxx/gc.log -Dsun.rmi.dgc.client.gcInterval=86400000 -Dsun.rmi.dgc.server.gcInterval=86400000 3057.609: [GC 2397254K->2385777K(2619328K), 0.0572310 secs] 3058.898: [GC 2402801K->2391301K(2619328K), 0.0566620 secs] 3059.940: [GC 2408325K->2397156K(2619328K), 0.0534080 secs] 3059.995: [GC 2397265K(2619328K), 0.0069950 secs] 3065.635: [GC 2414180K->2404934K(2619328K), 0.0732700 secs] 3065.849: [GC 2419994K(2619328K), 0.1150630 secs] 3070.248: [GC 1593931K->1591825K(2619328K), 0.1084230 secs] 3072.440: [GC 1608552K->1606431K(2619328K), 0.0533140 secs] 3087.759: [GC 1623455K->1614544K(2619328K), 0.0215850 secs] What event is causing the heap to shrink between the output at 3065.849 and 3070.248? Is there a VM param that will log it? I tried adding -verbose:gc but that does not change the output.

  • Java Out of memory - Out of heap size

    - by user1907849
    I downloaded the sample program , for file transfer between the client and server. When I try running the program with 1 GB file , I get the Exception in thread "main" java.lang.OutOfMemoryError: Java heap space at Client.main(Client.java:31).

  • mysql Incorrect Information in File: (corrupt) error

    - by Nick M.
    I've recently suffered from a power outage on one of my monitoring servers at the office. The result of that outage caused for some database tables to get corrupted.

  • Python parsing error message functions

    - by user1716168
    The code below was created by me with the help of many SO veterans: The code takes an entered math expression and splits it into operators and operands for later use. I have created two functions, the parsing function that splits, and the error function. I am having problems with the error function because it won't display my error messages and I feel the function is being ignored when the code runs. An error should print if an expression such as this is entered: 3//3+4,etc. where there are two operators together, or there are more than two operators in the expression overall, but the error messages dont print. My code is below: def errors(): numExtrapolation,opExtrapolation=parse(expression) if (len(numExtrapolation) == 3) and (len(opExtrapolation) !=2): print("Bad1") if (len(numExtrapolation) ==2) and (len(opExtrapolation) !=1): print("Bad2") def parse(expression): operators= set("*/+-") opExtrapolate= [] numExtrapolate= [] buff=[] for i in expression: if i in operators: numExtrapolate.append(''.join(buff)) buff= [] opExtrapolate.append(i) opExtrapolation=opExtrapolate else: buff.append(i) numExtrapolate.append(''.join(buff)) numExtrapolation=numExtrapolate #just some debugging print statements print(numExtrapolation) print("z:", len(opExtrapolation)) return numExtrapolation, opExtrapolation errors() Any help would be appreciated. Please don't introduce new code that is any more advanced than the code already here. I am looking for a solution to my problem... not large new code segments. Thanks.

  • Custom Error page | Redirect type =301?

    - by FlopScientist
    I guess this may be a novice question ( Which I am :) ). While redirecting user to custom error page, for e.g. 404, to tell that page wasn't found, the type of this redirect is 302. <error statusCode="404" redirect="/Utility/Error404.aspx" /> <error statusCode="400" redirect="/Utility/Error404.aspx" /> Is it possible to make this redirect 301 through Web.config? Thanks in advance to you all code maniacs.

  • git log throws error "ambiguous argument"

    - by LonelyPixel
    This used to work about a year ago. Now it doesn't: git log --abbrev=6 The expected result would be all commit hashes abbreviated to 6 characters. The actual result is now this error message: fatal: ambiguous argument '6': unknown revision or path not in the working tree. Use '--' to separate paths from revisions, like this: 'git [...] -- [...]' I have the impression that Git doesn't even know about that argument and tries to silently ignore its name but not the value. Using Git 1.8.1.msysgit.1 on Windows 7. Addition: Oh and it fails on other parameters, too. The entire command is: git log --abbrev=6 --format=format:"----- Commit %%h on %%ci by %%an -----%%n%%n%%B" If I just leave the abbrev part out, it still returns another error: fatal: Invalid object name 'format'.

  • How to delete a folder in python when [Error 32] is present

    - by harish
    I am using python 2.7. I want to delete a folder which may or may not be empty. The folder is handled by thread for file-monitoring. I am not able to kill thread but wanted to delete this folder any how. I tried with os.rmdir(Location) shutil.rmtree(Location) os.unlink(Location) But, it didn't work. It is showing error as [Error 32] The process cannot access the file because it is being used by another process: 'c:\\users\\cipher~1\\appdata\\local\\temp\\fis\\a0c433973524de528420bbd56f8ede609e6ea700' I want to delete folder a0c433973524de528420bbd56f8ede609e6ea700 or delete whole path will also suffice.

  • Django Import Error with URLS and ROOT_URLCONF confusion

    - by tipu
    The error can be seen here: http://djaffry.selfip.com:8080/ In httpd conf, <VirtualHost *:8080> ServerName tweet_search_engine DocumentRoot /var/www/microblogsearchengine/twingle </VirtualHost> <Directory /var/www/microblogsearchengine/twingle> SetHandler python-program PythonHandler django.core.handlers.modpython SetEnv DJANGO_SETTINGS_MODULE settings PythonOption django.root /var/www/microbloggingsearchengine/twingle PythonDebug On </Directory> Running python manage.py runserver and visiting localhost:8000 returns a splash page telling me everything is okay. However when I visit this site through apache, I get an import error with urls. In my settings.py file I have a line, ROOT_URLCONF = 'twingle.urls' I'm assuming this is the cause of the error. The project folder contains only 4 files: __init__.py manage.py settings.py urls.py I tried replacing twingle.urls with urls.py but then it gave me a different error. What is it I can do to get this working?

  • [Visual C++]Forcing memory alignment of variables/data-structures

    - by John
    I'm looking at using SSE and I gather aligning data on 16byte boundaries is recommended. There are two cases to consider: float data[4]; struct myystruct { float x,y,z,w; }; I'm not sure the first case can be done explicitly, though there's perhaps a compiler option I could use? In the second case I remember being able to control packing in old versions of GCC several years back, is this still possible?
