Servers polled with NPM 11.x and lower that are moved to an NPM 12 system for polling may crash and need to be rebooted after an NPM poll, likely due to a known issue with an F5 memory leak.  


NPM v12 and F5 devices


It is suggested to work with F5 on this issue. Refer to SOL14036: The BID-IP snmpd process may leak memory when polling for the number of members in a pool.  (© 2015 F5 Networks, Inc.
