Timeouts

May happen especially on slower computers. Try setting a different timeout (in seconds) :

-Dsurefire.forked.process.timeout=9999

"Server already running"

Known issue: JBPAPP-8368 Arquillian should wait until a port is free after AS JVM process ends to prevent "port in use".

Currently, the only solution is to re-run. This has been fixed in 7.1.2, see pull request https://github.com/jbossas/jboss-as/pull/1999 .

Database failures

Build gets stuck at first test of a module

If you use NFS (Network file system), it might be a file locking issue.

Try running using a local disk.
