Hi Mac,
By SNMP crashes, are you referring to seeing the following message in syslog?
Nov 6 04:44:01 Cambium-Device snmpd Watchdog:Abnormal SNMPd stop occured, restarting...
If so, this is not the cause of what Gary is seeing. This is a different issue and will have very little impact to normal operation. The SNMP process is a low priority process and if there is a lot of activity on the radio (both user and management traffic), the SNMP process on occasion, gets starved and crashes. However the process restarts itself in under 0.5 seconds. So unless you are doing rapid and continous SNMP polling on the radio to collect data, you will not see any impact due to this. Gary's issue of the ethernet link dropping on his SM is not related to the SNMP process restarting.
Thanks,
Sriram
