Sent before through my personal mail ID Hi, We experienced a seg fault (only one known occurrence so far) while sending the V2 traps out. I found the following link with exact location where I see the crash on our device. http://sourceforge.net/tracker/index.php?func=detail&aid=3078424&group_id=12694&atid=112694
As explained there, though our application is multi threaded, all the interaction with NetSNMP agent happens through only one thread and that shouldn't be a problem as per http://net-snmp.sourceforge.net/wiki/index.php/FAQ:Agent_43 I dont see any solution suggested in the link above for the seg fault. Anyone has any idea or suggestion how we can go about this? Here is the trace Program terminated with signal 11, Segmentation fault.
