Description Maciej Swiderski 2014-10-31 11:19:25 UTC 
Description of problem:
Running cluster for BPMS or BRMS with VFS clustered (helix and zookeeper) after any action on the repository that triggers social activity to be recorded VFS cluster is constantly synchronizing itself with other cluster members that is causing lots of errors and makes the CPU to be fully consumed by processing these synchronization events

Version-Release number of selected component (if applicable):


How reproducible:
Configure BPMS/BRMS cluster and clne repository on one of the cluster members

Steps to Reproduce:
1.
2.
3.

Actual results:
lots of synchronizations is being seen in the server logs and most of them are failing with GIT issues and CPU usage goes up to the top

Expected results:
only one sync is required as storing social event on one node should sync it to others
