We are using latest collectd and the plugin SNMP but we are facing an issue.
When a network switch device is not responsing, a segfault event is raised and collectd daemon gets killed.
 
Through the use of { snmp_gets }, we get the following:
snmpwalk -v 2c -c comstrg swicth IF-MIB::ifInOctets
Timeout: No Response from switch
 
This same switch configured in collectd fires a timeout (as a collectd error and a segfault event) even though it is the only device configured in collectd configuration file.
 
Here is some stacktrace:
