Hi,

 

I have a 4 cluster version 1.0.3 which was upgraded from 0.7.6 in 2 stages.

Upgrade to 1.0.0 run scrub on all nodes

Upgrade to 1.0.3

 

I keep getting this errors from time to time on all 4 nodes.

 

Is there any maintenance I can do to fix the problem?

I tried to run repair on the cluster a few times but it did not help.

 

Thanks in advance for your help.

 

Michael
