ISE Stunnel frequent restart

[pnavratil]

I found suspicious messages in ISE Report -> Audit -> Operations Audit. There is Stunnel Service started aprox. every 30 seconds on one PSN node (the rest 3 PSN nodes in deployment does not do this). The whole message:
----

ISE process was restarted by watchdog service

Event: Process: 'ISE Stunnel Service' started by ISE watchdog process

----

I did not detect any other problem on this node - it authenticates endpoints regulary, it reports all the data...

Is somebody met this behaviour? Is there any danger behind this?

Thank you for any help/advice.

Hi,

STunnel is an open source program installed in ISE but not used for ISE
functions. So these restarts won't be cuz functional problems however you
can open a tac case to see if you are hitting a bug which be resolve these
cosmetic messages.

Here is the list of open source programs used in ISE.
