I am getting these error messages one after the other every week on Win 2008 and SQL 2008 R2. MAX DOP is set at 1. Any idea how I can solve this?


DESCRIPTION: A fatal error occurred while reading the input stream from the network. The session will be terminated (input error: 64, output error: 0). DESCRIPTION: The client was unable to reuse a session with SPID 60, which had been reset for connection pooling. The failure ID is 29. This error may have been caused by an earlier operation failing. Check the error logs for failed operations immediately before this error message.

Unless you are running the newest builds this should be fixed by applying the latest CU (look down in the comments). Based on this bug/fix it appears to be a problem the CLR garbage collector.
