Description

We have a 2.2.5 cluster running in AWS VPC with EBS volumes. Earlier today 3 nodes seem to have gone into a bad state - clients were seeing high latencies when writing to these nodes, and the write to the commitlog on each of these nodes seemed high - more than the relatively low number of iops that AWS allocated to these volumes. While trying to understand the situation we attempted to restart the 3 nodes. We attempted to do a nodetool disablebinary; nodetool disablethrift; nodetool flush. and then stop the process.

When trying to disablethrift, the following stack trace appeared in the system.log:

```

The attached jstack was taken from a node after the above was noticed.
