Symptoms

Upon restart of pau service, it fails to start with the following messages in console.log:

JBAS011048: Failed to construct component instance
...
concurrent access timeout on org.jboss.invocation.InterceptorContext$Invocation@7079c030 - could not obtain lock within 5000MILLISECONDS
...
Services which failed to start: service jboss.deployment.subunit."pau-ear.ear"."poakernel-ejb.jar"

Howerver, WildFly java process was still alive and further attempts to restart pau fail with different error and create new WildFly instance:

Caused by: java.net.BindException: Address already in use

Cause

Hostname of OA management node was not included in local hosts file. It is required by JBoss/WildFly to start and work properly.

Resolution

  1. Kill all existing JBoss/Wildfly processes.
  2. Add OA Management node's backnet address and a hostname to /etc/hosts file.
  3. Start pau service.
