I have found that taking the snmp module out of the config allows the command to complete without crashing opensips. This hasn't always been the case but I don't know what revision the problem started with.
I also don't have the opensips snmp config completely set up on this server. Everything is in place except the agentXSocket listen parameter being set for the snmpstats module. I'll try to test this again with that in place before the end of the day.
