High authentication latency

Dear Guru's,

Since yesterday we are encountering "high authentication latency" errors on one of our 3 PSN's. Our system is already up/running for 3months, so the latency can't be explained by increased AAA traffic. Suddenly CPU was at 40%, memory at 45% and latency >1000ms causing timeouts in AAA.

We are running ISE 2.0 Patch #3

Is this a bug ? 

Can be checked what is the cause of the high latency ?

Kind Regards,
