Can you help update in iMC ......?

Wireshark is not going to say "This is an error". It is not going to highlight a particular packet. You need to follow the streams, look at the contents, match it up with the logs, follow what's going on, and try to understand why IMC is stopping.

It might be something like an SNMP response that asks for a specific OID, but the switch says that OID doesn't exist, or there's no data returned, etc. Or it might be in the Telnet sessions, where IMC is expecting some specific output, but doesn't see it.
