The only thing I found similar behavior here: https://groups.google.com/forum/#!searchin/scalr-discuss/SzrMessaging/scalr-discuss/VxgvY3SYuqo/OIUrgP3zRsQJ In messagingqueue.log appears: 2012-09-05 20:32:34,744 - INFO [tran5047b2ca8c83c:Logger@718] - 'Child PID: 23946 *crashed* (status: 9, wifexited: , wifsignaled: 1)' 2012-09-05 20:32:34,744 - INFO [tran5047b2ca8c83c:Logger@734] - 'Flag stopForking=1 prevents new process forking' 2012-09-05 20:32:34,744 - INFO [tran5047b2ca8c83c:Logger@370] - 'wait() from child 23967.
