This morning we have detected several long running queries executing on mssql04.ihostasp.net database server that are causing process blocks and are preventing other processes from completing. Unfortunately, it appears that these processes are deadlocked and are not responding to "kill" command. As the result, we must restart entire MSSQL service in order to flush them out.
We expect all services on MSSQL04 to resume normal operation by 9:40AM EST, we will post updates in this thread.
