I experienced the same problem with the SNMPstats module. If you run openser in foreground mode (fork=no), the module doesn't initialize. Running in background mode fixes the problem.

New subject: Fwd: [Users] SNMPstats module not returning data

I didn't realize you weren't forking. :-) Does the crash happen even without the snmpstats.so module being loaded? If so, I probably can't help you any further until we figure out what is causing the crash. Keep me posted! - Jeffrey Magder Sergio Gutierrez wrote:

Thanks Terry But now there is a Problem (I just reported either). When I run openser with fork=yes, it crashes! I have an open thread which begun by reporting an issue about openser crashin when compiled on 64 bits; right now it is running compiled on 32 bits, but, when it is started with for=yes, it crashes. This is the URL of the report. http://openser.org/pipermail/users/2007-March/010035.html Thanks!

New subject: Fwd: [Users] SNMPstats module not returning data

We eventually figured out what the problem was. Running "make clean" and then recompiling a fresh copy fixed all of the crashing issues. Because of some earlier linking issues before the make clean, there were errors in how structures were accessed. This eventually lead to a segfault. This is related to the problem and fix listed in the "Openser fails when compiled on Solaris 64bit" thread. Cheers! - Jeffrey Magder Jeffrey Magder wrote:
