I'm having a very odd problem with my CUC cluster. It happens after a split-brain caused by a network issue. The sub and pub go into split brain and once the network problem is resolved and they can talk, the sub goes into high utilization and the queue on the pub just backs up and is never delivered. I've even tried doing a full cluster reboot and it doesn't seem to solve the problem. During this scenario neither nodes are answering calls so incoming callers get a busy and users can't check their voicemail.
The back story is that it first happened after a link between the two buildings was disconnected for about 30 seconds during maintenance. I ended up leaving the sub down for a couple of weeks and things seemed to be OK when it came back up. Then the next time it happened was recently when we did a switch upgrade. Exactly the same thing happens, one node...usually the sub, goes into high CPU (i see it on the VMware console) and the queue on the pub backs up.
Anyone have any thoughts on how I can proceed to troubleshoot this? The worst part is I will basically have to do it late at night so as not to affect the users!
Thanks in advance!

Thanks for the suggestion Rob. The thing is, the pub stops taking calls and the sub is in high CPU and the queue on the pub keeps getting bigger. Also the split brain never clears.
