So here are the messages. For some reason controller1 always produces message1
and controller2 - message 2.
MESSAGE1:
2006-12-27 17:43:46,524 WARN controller.RequestManager.camps_index Unexpected
answer from controller Member(address=/XXX.XX.XX.XXX:7800, uid=camps_index)
(null) for request INSERT INTO CAMPS_INDEX(customerId,order...
MESSAGE2:
2006-12-27 17:43:49,328 INFO controller.RequestManager.camps_index Unable to
find request INSERT INTO CAMPS_INDEX(customerId,order... in list of requests
that failed on all backends.
