I have been having plenty of problems (on 0.7.0, http://www.mail-archive.com/user@cassandra.apache.org/msg09341.html, http://www.mail-archive.com/user@cassandra.apache.org/msg09230.html, http://www.mail-archive.com/user@cassandra.apache.org/msg09122.html, http://www.mail-archive.com/dev@cassandra.apache.org/msg01746.html, and from others: http://www.mail-archive.com/user@cassandra.apache.org/msg09838.html,) which are very similar to what was reported and apparently fixed for this case. In my instance, I have not been able to find a reproducible case but its not all that feasible to log what is going into my nodes. Could this bug have existed in 0.7.0 in another form or could this problem occur elsewhere in the code?
