Description

I ran my cluster for about 2 days. the cluster has 2 nodes. I restarted one box several times, and the other one was always running. the one always running ended up accumulating 100GB of commit logs.

this is 1.0.0 code from about Sept 15 in github. I kept the original setting for
#commitlog_total_space_in_mb: 4096
i.e. commented out

here is some sample of the output:
