Hi @Malako-7845,
you can clear the cache, especially in such situations. Here is more on the topic and as you will see it is almost a "standard" troubleshooting procedure. I personally do it quite often when I have issues with the management servers (MS cache) or the console:
How and When to Clear the Cache
and
What does the option "Flushing the Health Service and State and Cache" do?
About putting your MS server in MM: I think this won't be much of a deal, but this depends on your monitored infrastructure. There is a workaround for that - an admin task, which you can trigger, which does the same as putting the server into MM. The task's name is "Resubmit local cache for state change events"
Hope this answers your question.
Regards,
Stoyan
