Hello People
I have a strange issue where mgt server times out to send a command to
secondary storage VM every hour and because of this UI won't be accessible
for a short duration of time. Sometimes I have to restart mgt server to get
it back to working state and sometimes I don't need to restart it. I also
see some exceptions while fetching the storage stats.
The log says secondary storage VM is lagging behind mgt server in ping and
it sends a disconnect message to other components. Can you let me know how
to troubleshoot this issue? I destroyed the secondary storage VM but the
issue still persists. I checked the date/time on the mgt server and SSVM
and they are same. This is happening for quite a few days now. Below are
the logs
