Subject unable to rename commitlog, cassandra can't accept writes
Date Sun, 08 Jul 2012 01:26:18 GMT
Hi,

I'm running Casandra 1.1.2 on Java 7 x64 on Win7 sp1 x64 (all latest
versions).  If it matters, I'm using a late version of Astyanax as my
client.

I'm using 4 threads to write a lot of data into a single CF.

After several minutes of load (~ 30m at last incident), Cassandra stops
accepting writes (client reports an OperationTimeoutException).  I looked
at the logs and I see on the Cassandra server:

>>>>
