Hi,

I need some "light" to get a solution. Probably there are tons of things that cause this problem, but maybe somebody could help me.

Scenario: a Windows server running 24/7 a PostgreSQL database and others server applications (for processing tasks on database, etc...). There are differents servers scenarios (~30), with different hardware and windows versions (XP SP3/ WinServer, etc... all NT based). All aplications were written in Delphi7, and link to DLLs (in D7 also).

After some days (sometimes a week, sometimes a couple of months), Windows begins to act strange, like not opening start menu, some buttons are missing in dialogs. And soon some applications do not open, raising a event on eventviewer:

Faulting application x, version y, faulting module kernel32.dll, version 5.1.2600.5781, fault address 0x00012afb

In mean while, others applications open fine, like notepad, iexplore, etc... but SOME of my applications don't, with only event log described above. But if we do not restart system, in a few days even cmd.exe stops open, (and all other applications) with same error on eventlog.

I've tried to find 'what' can cause this, but with no sucess. So, and any advice will be welcome.

Thanks in advance.
