PostgreSQL version: 8.3.7.1
Operating system: Windows Server 2003 SP2
Description: PostgreSQL 8.3.7 crashes on Win2003 logoff
Details:

Hi!

That's what i have done:

Installed postgresql-8.3.7-1-windows.exe on Windows Server 2003 SP2 with one
click installer.

Create some load on the machine by running example program testlibpq.exe a
lot from a remote host. This is done by a perl script re-running
testlibpq.exe in an endless loop started 20 times.

Logoff remote desktop connection from WinSrv2003: CRASH

No postgres process running any more.
Old 8.3.5 used before even can not be restarted!!! Server boot is
necessary!
But the 8.3.7 can be restarted and crashes again by repeating above
scenario:

Sorry for the German/English log message mixture, but selecting English
during installation didn't fix it?!

The crash seems to be related to CreateProcess-Calls for new clients
arriving and Windows Logoff handling. Sometimes postgres.exe reports system
error 0xc0000142: Some ressources are missing.
