Subject Leveldb not recovering from failover
Date Tue, 15 Mar 2016 15:58:52 GMT
I have a 3 node cluster on Redhat servers running ActiveMQ version 5.13.2 and
Zookeeper 3.4.8

The system runs without error for days then when I fail it over it will
sometimes will not recover see log segment below.
The strange thing is I’m getting a Connection refused even from the master
connecting to itself.

Does anyone have any idea what might cause this?
