We seem to have a problem with the hanging maven module builds. The status of the actual build itself shows completed, however the maven modules shows running. The stuck module builds makes the succeeding module builds to be incomplete. Following are the threadDump stack trace from the slave node and not sure the WAITING messages in the threadDump info are the real cause of the issue. The slave itself has been configured with 6 executors in order to execute multiple jobs and Maven 3 is the version used. Need experts advice and a solution to this issue..
