We are also getting similar error on our SQL server in cluster environment
TCP connection closed but a child process of SQL Server may be holding a duplicate of the connection's socket. Consider enabling the TcpAbortiveClose SQL Server registry setting and restarting SQL Server. If the problem persists, contact Technical Support.
Below articles suggest to install CUP 6 on SQL 2008 R2 and a hotfix on Windows 2008 R2
But we are already running on higher version than suggested in above article. Our server is running with SQL 2008 R2 SP1 and Windows server 2008 R2 SP1, still we are getting above error. Has anybody faced similar issue on SQL 2008 R2 SP1. Any suggestion would be appreciated.
Thanks in advanced,
