Publishing performance CQ5.6 - increasing threads

[Salvatore_Gallo]

I have a problem with my publish instance.
The number of threads instantiated reaches over 350 and never decreases.

After some time the publish does not respond, forcing me to restart.

From the thread dump I see that there are many threads in status: Object.wait (). These are all generated by the GET calls received by the dispatcher.

Anyone have any idea what could be causing it?

Best regards.

Thank you

When trying to understand a thread dump the key is to look at the RUNNABLE threads to understand why they hold contention over the WAITING threads.  

Also CQ 5.6 has been end of life since 2016.   Upgrade
