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

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 (https://www.veritas.com/support/en_US/article.100041057)
Not sure if you are seeing any instability with spoold. There was another link (Non-Veritas: https://wiriadi.wordpress.com/2018/04/04/msdp-performance-issue-after-upgrading-to-netbackup-8-1-app...) that indicates some of the possible symptoms as being:
Hope this helps,
