Hi gents, I have a CentOS 6.6 install with net-snmp running. I'm using SNMPv3 Auth and Encryption with Observium polling devices every five minutes. On one of my Centos server, the net-snmp process will die after 24-36 hours of running. It seems to be hitting my system maximum file open limit which is set to 1024.

It seems that CentOS is frozen to net-snmp 5.5 and I'm don't really want to use anything that I can't easily manage with "yum". The weird thing is that I have another server with the same config/CentOS version/Net-Snmp version and I have no issues with the snmp process on that server. Anything else I could try to troubleshoot the issue? Thanks! ------------------------------------------------------------------------------ Dive into the World of Parallel Programming!
