Hi CJFarrar,
This could be caused by an infinite loop.
When the standard behavior that fails the deployment process when errors happen had been modified (for some reasons, e.g. error handling for known errors). The reason for modifying the default behavior might be valid. However some unforeseen circumstances happened that was not handled properly. The faulty handler produced an infinite loop.
We experience the similar thing which caused by such infinite loop, however the one that noticeably blew up at that time was the Oracle database tablespace.
