Hello
It appears that our production ISE 2.3 patch 1 has had this error for a few months and it's gone unnoticed. It says to contact the TAC and I have done some searches. Apparently the resolution is to run
application configure ise
Select option 7 to reset the session DB.
But I am annoyed with this because there is no reason given as to what is causing this, and why I need to take remediation. Why can't this thing just run normally without us opening a TAC case once a week? Is this yet another bug ? I don't need to join the ISE 2.4 beta because I appear to never have left the ISE 2.2 and 2.3 betas ...
