Hey guys.
I had a strange problem with a 1.1.0: I have a 3 node cluster and
yesterday one of the nodes started to run GC one after another, causing the
cluster to become unavailable until I restarted the one node.

Any ideas?

I'm assuming this log is on a single node. Looking at it, it seems like the
GC just couldn't free anything up so is it possible that you just
physically need more RAM than 11G on this node to handle the load on it?
