HP SIM 6.0 does not acknowledge the error is fixed

[ChristianWickham]

We recently started using HP SIM after it had been idle for a few months.
Some servers were reporting that a network link was down, but that was because they were 2 NIC systems where only one NIC was connected. We resolved this by disabling one network card, and SMH reports that everything is fine, but HP SIM still reports that "a network interface has failed".
I have tried clearing the IML, tried rebooting, even re-installing agents, but SIM still reports it as an error.
How can I mark this as resolved in SIM?

Other systems also report "SNMP passthrough" or "There is a server problem that is degrading functionality" - but the server has no issues and nothing in any log reporting the issue or what it is. How can I diagnose and resolve this?

Go to SMH of server,
then change SMH source to SNMP, then u cat found on main page notification about "Integrated Management Log", open it and look at red messages.
