Subject COMMIT-LOG_WRITER Assertion Error
Date Mon, 09 Aug 2010 19:30:54 GMT
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:
