Strange "Address already in use" error
I'm testing a simple Cassandra cluster on two machines. For some reaon
after a while one of the nodes in the cluster crashes.
At first I thought the fault was on me, so I simply started it up again.
After the second time this happenned I noticed the following message errors -
INFO 17:28:05,624 Mycolumnfamily has reached its threshold; switching
in a fresh Memtable at
CommitLogContext(file='/var/lib/cassandra/commitlogMY/CommitLog-1278858485610.log',
position=116)

Exception encountered during startup.
Obviously nothing has changed on the machines, I'm using default ports
that aren't taken by any other application (I saw people had problems
with 8080, but it's not used on my machines. 9160 isn't either). When
I started up cassandra again on both nodes, things worked just fine
(until further notice at least).
So I'm kind of at a loss here.
Any idea as to what is wrong would be appreciated
Thank you.

Something is already using the port (probably 7000 (default, used internal by cassandra)) you tried to bind.
Use e.g. 'lsof -i' to investigate the port usage further.
