Description (partial)

Realod due to sys-mgr crash, and core file is created.

Multiple messages were sent to sysmgr to fill up the stats table to max limit and while cleaning up the table it is not reinitiated properly causing table corruption.  A combination of following  commands/conditions could cause  sysmgr stats table to fillup.
Sending snmp queries to process MIB/system MIB.
Show processes  <> commands
Show system internal  sysmgr service <> commands
Standby reset
process start/stop 
( The above commands/events internally triggers an MTS message and these MTS message will update the same entry and it does not allocate new entries for every instance. For example, if a process is restarted then new entry is not created just the existing entry will updated)
