Hi Devon, thanks!
* I don't think there was a core dump. At least that is not stated in /var/log/messages and I don't find anything relevant in /var/spool/abrt/ * I am running 3.7.1 * The addr2line returns ??:0. Also with gdb: > gdb /usr/lib64/libganglia.so.0.0.0 ... Reading symbols from /usr/lib64/libganglia.so.0.0.0...(no debugging symbols found)...done. Some more information about my setup: - I am running several gmonds in the same machine, so all my data_sources are to localhost. Cumprimentos / Best regards, Cristóvão José Domingues Cordeiro ________________________________________ From: Devon H.

I have a couple of initial questions that might help figure out the problem: * Did you get a core dump? * What version of ganglia are you running? * This crash happened within libganglia.so at offset 0xb7b0. Can you run: $ addr2line -e /path/to/libganglia.so.0.0.0 0xb7b0 and paste the output? If that does not work, there are a couple other things we can try to get information about the fault, but hopefully we can just work from there. Kind regards, Devon H.
