  Dear all,

  I have always on secondary server which supports Read only workload. The read only queries have been smooth for several months.

  Yesterday the read only queries were blocked by a system process ( spid 44 ). on From Sysprocesses I understand that the system process command type was DBStartup. The replica state is also synchronizing ( aysnc mode ) and healthy. Any clue why such a behaviour? thanks

  Regards,
  Raj

  That is not usual , you mentioned queries not a single query which got blocked . SPID 44 blocked multiple queries ?

  Please check error logs of sql server for any unusual entries. Also, did you apply any service pack in recent past and this problem popped after it?
