My first thought was KMS was overloaded, but you state KMS restart doesn't
help
Can you please confirm
1) KMS process died as a result of KMS stop
2) KMS have started after that and the problem persist?
I do remember I had situation on demo
KMS has been stalled and restart did nothing
kill -9
+start
did the job
I'm sure you have checked memory/cpu?

This one is happens if OM trying to re-connect to KMS
It can be ignored if you can see ""!!! Kurento connected"" later in the logs
