> -----------------------------------------------
>
> Key: CASSANDRA-6476
> URL: https://issues.apache.org/jira/browse/CASSANDRA-6476
> Project: Cassandra
> Issue Type: Bug
> Environment: Cassandra 2.0.2 DCE, Cassandra 1.2.15
> Reporter: Theo Hultberg
> Assignee: Brandon Williams
>
> Two of the three Cassandra nodes in one of our clusters just started behaving
> very strange about an hour ago. Within a minute of each other they started
> logging AssertionErrors (see stack traces here:
> https://gist.github.com/iconara/7917438) over and over again. The client lost
> connection with the nodes at roughly the same time. The nodes were still up,
> and even if no clients were connected to them they continued logging the same
> errors over and over.
> The errors are in the native transport (specifically
> MessagingService.addCallback) which makes me suspect that it has something to
> do with a test that we started running this afternoon. I've just implemented
> support for frame compression in my CQL driver cql-rb. About two hours before
> this happened I deployed a version of the application which enabled Snappy
> compression on all frames larger than 64 bytes. It's not impossible that
> there is a bug somewhere in the driver or compression library that caused
> this -- but at the same time, it feels like it shouldn't be possible to make
> C* a zombie with a bad frame.
> Restarting seems to have got them back running again, but I suspect they will
> go down again sooner or later.
