My Ant build was failing yesterday with the code: RESULT=137 sortly after something was Killed. After a certain amount of frantic Googling with no results I decided to look at the processes which are running on the server. There were about 20 Javas there and one defunct one so I decided to kill them all off. That seemed to do the tricked. I think Ant was killing the compile tasj that was taking too long as it was getting blocked some how by the extraneous Java processes. Had me worried there for a second. It's interesting though that I immediately assumed a third party had changed something when the daily build broke. My new mantra is: when Linux goes bad on you, check the ps and check lsof before you attempt anything wackier.
