----------------------------------------------------------------

What do you mean? That assertion is from my logs yesterday? Been able to repro it 3-4 times
during the last couple of days. I couldn't repro it on 1.1. (at least not so far)

The question was asked in the Cassandra User list to open a new bug or just edit the old one.
Thats why I created a new one. (http://www.mail-archive.com/user@cassandra.apache.org/msg27686.html)

> We are seeing AntiEntropy errors when performing repair jobs in one of our Cassandra
clusters. It seems to have started with 1.2. (maybe an issue with vnodes) The exceptions occur
almost every time we try to do a repair on all column families in the cluster. Doing the same
task on 1.1 does not trigger this.
> 6 nodes cluster (vnodes, murmur3, rf:3)
> very low activity
> running a nodetool repair -pr loop on the cluster nodes
> nodetool hangs, and same big stacktrace in logs.
