I have two application servers which connect to the db server with various dbs by using SQL Server Native Client 10.0 (Version 2007.100.4000.0). After a fews the connection to db server gets lost. The following error is logged:
ProcessID:2452 ,ThreadID:1408 : NiJ - E - 28/08/2012-08:04:46 - \PCV/src/ni/src/pcvnijournal.cpp - 2842 - PcvNiJournal::isRetrievePending() - DB Exception.Error: SMux Provider: Physical connection is not usable [xFFFFFFFF].
Unable to open a logical session
- State:08S02,Native:-1,Origin:[Microsoft][SQL Server Native Client 10.0]
State:08S02,Native:-1,Origin:[Microsoft][SQL Server Native Client 10.0]
Afterwards we have to restart SQL Server to get it working again.
Db server uses SQL Server 2008 SP2 Standard 64-Bit. There is no error in SQL Server Logs. Auto Close setting is set to False on alll dbs.
Any way we can track down the problem?
