Storm: Nimbus crashing

[#1]

Hi all,

I've got some instability in Storm, my nimbus server is crashing with the following message. Anyone is familiar with it ? Is it linked to memory constraint ( sandbox ) ?

2015-10-01T07:41:48.268+0000 o.a.t.s.AbstractNonblockingServer$FrameBuffer [ERROR] Unexpected throwable while invoking!
java.lang.RuntimeException: not a leader, current leader is NimbusInfo{host='sandbox.hortonworks.com', port=6627, isLeader=true}

Thanks,

Olivier

Shouldn't be a memory constraint. Did you try deleting storm-local dir you can find the location storm.local.dir in /etc/storm/conf/storm.yaml. Stop storm services delete this dir and restart the nimbus.
