      I'm having this really strange issue where Net-SNMP will restart every ~5 minutes, I do not see anything in the system logs about it exiting or the like, but if I monitor ps -o etime -p $(pgrep snmp) it restarts after ~5 minutes. I have 18 firewalls with SNMP and it happens consistently on like 3 of them.

      It doesn't happen all of the time, but usually overnight it will restart then get stuck in the restart loop for a while.

      pfSense 2.7.2
      pfsense-pkg-net-snmp 0.1.5_11
      net-snmp 5.9.1_4,1

          @cct-ckatri do you have both net-snmp and bsnmp enabled?

            @dennypage yes, bsnmp is setup to bind only to localhost, net-snmp is set to bind only on WAN, then I have proxy -v2c -c public 127.0.0.1:161 .1.3.6.1.4.1.12325 added to the advanced options in the net-snmp config.

            I have this same exact setup on a bunch of pfSenses, but this issue only happens on like 3 of them.
