Unfortunately no. We need to analyze the core dump that's generated by the kernel when snmpd segfaults. To make sure the core dump will be created, you need to check that "ulimit -c" is set to "unlimited" when snmpd is started. Easiest way to do that is to edit /etc/init.d/snmpd and add "ulimit -c unlimited" just before 'echo -n "Starting snmpd"'. Let me know if you need more help with that. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Good morning, I've edit snmpd start script: #echo -n "Starting snmpd" ulimit -c unlimited echo -n "Starting snmpd" startproc $SNMPD $SNMPDCONF -r -A -LF ${SNMPD_LOGLEVEL:-n} $SNMPD_LOGFILE -p $SNMPD_PID $agentargs $SNMPDNOSMUX $SNMPDNOTCPWRAPPERLOG rc_status -v rc_reset After edit I've restarted it. The daemon crashed tonight, but there is no core dump in the messages or ssh console ? What I missed ?
