Steps to Reproduce

  1. Log in to the application
  2. Configure more than twenty file listeners on a node
  3. Start the node

Root Cause

Incorrect configuration in the Service Package for the file listeners in the Service Pooling options. As a result, the file listener threads are kept waiting on obtaining or borrowing a requestor.


Perform the following local-change:

Change the MaxIdle, maxActive, maxWait properties to their default values of 10,10,10 respectively.
