Just throwing this out there as it could be a concern. I had a cluster of 3
nodes running. Over the weekend I updated to trunc (Aug 9th @ 2pm). Today, I
came to run my daily tests and my client kept giving me TSocket timeouts.
Checking the error log of Cassandra servers, all 3 nodes had this and they all
became unresponsive! Not sure how to reproduce this but a restart of all 3
nodes fixed the issue:
ERROR [COMMIT-LOG-WRITER] 2010-08-09 11:30:27,722 CassandraDaemon.java (line
82) Uncaught exception in thread Thread[COMMIT-LOG-WRITER,5,main]
