Notes/Domino 4 and 5 Forum

We have a Domino Server 5.0.11 running on a Windows 2003 Server.

Everything was fine during 2 years but suddenly the server starts to hang, sometimes a application popup error message appears (bt_context, panic, nserver.exe, namgr or even nupdall.exe) or sometimes just hang with no messages.

Also, once we had the following message:
Application popup: nSERVER.EXE - Application Error : The instruction at "0x013ac585" referenced memory at "0x00100007". The memory could not be "written". But only once...

In the Notes log, no error is registered, and QNC don't create a notes.rip file. So I will disable this debugger.

I am thinking in make some local maintenance in the NAB, replace the .EXE files, even reinstall the server, but I am not sure if it will solve the problem.

I didn't find anything real and reliable in all the others post here about this kind of crash/hang on the Domino.

Any ideas how to figure out this king of problem with sure?
