JBAS014516: Failed to acquire a permit within 5 MINUTES
I am currently running wildfly 8.1.0CR1 but I have seen this exception in other releases as well. It seems to happen when memory comes under stress. I gather that the StrictMaxPool is configured in the standalone.xml by this configuration:
<pools>
<bean-instance-pools>
<!-- A sample strict max pool configuration -->
<strict-max-pool name="slsb-strict-max-pool" max-pool-size="20" instance-acquisition-timeout="5" instance-acquisition-timeout-unit="MINUTES"/>
<strict-max-pool name="mdb-strict-max-pool" max-pool-size="20" instance-acquisition-timeout="5" instance-acquisition-timeout-unit="MINUTES"/>
</bean-instance-pools>
</pools>
Just so I understand, when I get this timeout exception it tells me that I had 20 active concurrent requests on my session bean with some other number of requests blocked on the Semaphore contained in the StrictMaxPool, correct? I am wondering if there is any way I can add a user hook in this call chain such that when this exception is thrown I can force a thread dump so I can see where all the requests are blocking?
