We are observing a very strange behaviour in universal messaging. its installed on Linux server. The CPU usage increases suddenly and the processing starts to slow down. when we restart the UM the CPU usage as well as the processing goes back to normal.
I also noticed that this server has no activity in the JVM GC stats graph for this server.
few memory level setting in the Server_Common.conf file are as below.
On checking the load and transaction volume its almost same as any other day.
