Hi List:
We have a multi-master set-up: 1 Primary Master, 1 Cold Master, 3 Consumers.All usually humming well - however today, there were a number of deadlocks - like below - 2 of which brought the 1 Primary Master (example below from 'error' logs resulted in master going offline).
Any ideas on where to look on what could have caused the deadlock and the subsequent taking offline of the Primary Master?
Thanks.
