MRG-M 3.0: Queue doesn't always return all empty journal files to the pool

Solution Verified - Updated -

Issue

Removing all durable messages from a durable queue (backed by a linear store) by either way:

  • purging them
  • removing due to time-to-live expired
  • normally consuming them

ends up in a situation, where the journal for the queue has many journal files, despite the queue became empty. All those files except one are supposed to be returned back to Empty File Pool (EFP).

Usually, the "all message removal" action shrinks the number of journal files to one tenth.

Why the journal keeps some files in and does not move them to EFP?
