    We've recently upgraded to Hudson ver. 1.358 and upgraded our Hudson plugins (CheckStyle, FindBugs, Emma, etc). Since taking the upgrades, we're noticing that slave agents are terminating after building our 'code checking' project, which consists of: - CheckStyle (now on 3.6) - FindBugs (now on 4.8) - Emma coverage reports (now on 1.20) We've narrowed the problem down to the Emma plugin; the Hudson slave does not terminate when I deactivate the "Record Emma coverage report" step in my Hudson project. When I re-enable the Emma coverage report step, the Hudson slave starts dying again. Slave agents are happily building our other builds (junit tests, end-2-end tests). Here's some logging below: (please let me know, if you need more details) ============================== When this happens, his is the logging we see on the: 1) Hudson server log file: 17-May-2010 12:49:29 hudson.TcpSlaveAgentListener$ConnectionHandler run INFO: Accepted connection #36 from /xx.xx.xx.xx:38048 17-May-2010 12:49:29 hudson.TcpSlaveAgentListener$ConnectionHandler error WARNING: Connection #36 is aborted: cislave3 is already connected to this master.
