[Observium] pfSense SNMP daemon crashes after update to r4711

Hello guys,

yesterday I updated my Observium (Centos 6.4) to the r4711 and I noticed that all my pfSense firewalls (5 hosts, two 2.0.3 and three 2.1) became down.

On every host, the SNMP daemon was crashed. I tried to restart the daemon on every pfSense, but it crashed again and it seems to me that it crashes during the next cycle of polling (the discovery seems to go fine).

Today I tried to update to the r4715 but I'm experiencing the same problem.

Has anyone experienced something like that? How can I go deeper?

Thanks for any hints,

Kind Regards

Stefano
