Subject: SNMPD crash
Hello!
I use net-snmp-5.3.0.1-1.EL4 with dynamic module.
We performed some load test and after 10 hours snmpd had crashed.
Below you may see back trace from the core.
I would like to mention that load test sends exactly same trap (i.e. the
payload of snmp packet exactly same).
I saw that snmp_oid_compare doesn't comare whether it receives NULL
pointers or wrong sizes and I understand that snmpd crashed since wrong
input.
Do you have any ideas?
Thanks ahead, Vlad.
P.S
I found the problem for crash from my previous letter.
It happened also in load test in multithreading environment.
The problem was fixed by synchronization of trap sending.
