    Description

      We have experiencing a problem on our OSS servers. The server load shoot up to as high a 500, with dead io threads, the ost's become unusable until the OSS is rebooted. This has happened 5 times on 4 different OSS server in the last 48 hours. I've attached messages file from the server that was last affected.
