LEM Events stop updating Filters

All,

Monitoring LEM over the last two months, I have noticed LEM has twice had a database issue causing LEM not to display any events.  On both occasions, LEM syslog shows LEM receives data from devices.  Looking at the hypervisor, it does not show any alarms for the LEM VM.  I finally got LEM to display events in filters after I issued a dbrestart.  Any thoughts on how I can further troubleshoot the cause of this issue?

Thank you,
