Active transactions prevent replication startup

  Explanation:  The Log Catch Server (LCS) is unable  to  complete
  the  catch-up phase of replication startup.  Active transactions
  prevented the  LCS  from  acquiring  a  quiet-point  within  the
  specified interval.

  User Action:  Ensure that no extremely long-running  transaction
  are active.  Increase the LCS quiet-point timeout interval.
