MSDP manual queue processing delay

Level 6

Strange issue on a replication-target appliance (5230 - v.3.1):

MSDP fills up, I expire some images, and initiate a manual queue processing run.  I'm watching the storaged.log and it has been over an HOUR since I submitted the queue processing command:

June 21 14:03:22 INFO [139655922538240]: Queue processing finish.
June 21 15:06:28 INFO [139655922538240]: Queue processing triggered by external request.

This is an awfully long delay - so I checked the last couple "regularly scheduled" queue runs:

June 21 00:20:03 INFO [139655922538240]: Queue processing triggered by external request.
June 21 02:07:28 INFO [139655922538240]: Get 68944-69076 tlog files to be processed from /msdp/data/dp1/pdvol/queue

June 21 12:20:03 INFO [139655922538240]: Queue processing triggered by external request.

Anyone else seen this?  System is not busy according to top:

Hi Elanmbx,

You don't say if this appliance has recently been upgraded to 3.1.  If so, this one could be a possibility:

NetBackup Deduplication Engine (spoold) crashes after upgrade to NetBackup version 8.1 or NetBackup Appliances 3.1 (

Not sure if you are seeing any instability with spoold.  There was another link (Non-Veritas: that indicates some of the possible symptoms as being:

  • NetBackup Deduplication Engine (spoold) crashing
  • Replication and/or duplication hanging
  • General slowness for MSDP-related operations

Hope this helps,
