EV11 Storage Queue

Hi,

Just upgraded to EV11.0.1 hotfix 2 (Windows 2008 R2) and I'm seeing the below events.

I have the Safety Copy setting as "No, remove immediately after archive" and my monitoring showed the Queue Total Length and Queue Pending Length at around 50,000 items (the pending being a few hundred less than the total) and around 20GB for a large part of the overnight archiving window. This morning it's all back to "normal" 0 items and the space is recovered.

Does this seem "normal"?

I've tried researching the event and can't find anything, is there any "tuning" available?

Thanks,
