PMP Critical after 7.50 agent updates

[Rob Buxton]

Hi All,
On a number of servers, PMP is showing the red critical flag and is not accessible after updating the agents to 7.50.
The only common thread I can find is that the those that have done this are DL360's, various generations. These were working fine.
It does not immediately show after the update, but we remove the Remote Insight Agent, restart the agents and then the icon goes red.
No amount of coaxing will bring it back, stop/restart agents, stop/start PMP Monitoring stop/restart PMP service. Even rebooted the HPSIM server.
On a similar tack, some of the agents where I've set the Remote Insight Agent as removed and restarted the agents continue to show the ILO details. An Orange alert as they're not connected.
I'm planning on updating to 7.51 to see if this fixes any of the above, but as these are production servers there's a schedule to follow. Just seeing if anyone has seen similar.
