From f4a34ee89ce3c1e2e1b92ff2ebf9d79bc517e57b Mon Sep 17 00:00:00 2001 From: Mark Michelson Date: Wed, 15 Aug 2012 23:35:35 +0000 Subject: [PATCH] Fix bug where final queue member would not be removed from memory. If a static queue had realtime members, then there could be a potential for those realtime members not to be properly deleted from memory. If the queue's members were loaded from realtime and then all the members were deleted from the backend, then the queue would still think these members existed. The reason was that there was a short- circuit in code such that if there were no members found in the backend, then the queue would not be updated to reflect this. Note that this only affected static queues with realtime members. Realtime queues with realtime members were unaffected by this issue. (closes issue ASTERISK-19793) reported by Marcus Haas ........
