call recording trouble trixbox 2.2 freepbx 2.4 -- anyone else?

Call recording on demand *1 has become very flaky for us recently. The system will record maybe 1 out of every 20 calls we ask it to. The behavior persists across different phone types and seems to be system wide. We are only talking maybe one call being recorded here at any given time out of maybe three total. The system is otherwise stable, fast, and has no other bugs; freepbx is fully up to date as of today's patch releases for core and ivr. I should note that call recording seemed to work fine before the upgrade to freepbx 2.4, but I don't want to put the blame there and file a bug report unless others are experiencing the same thing.

So, anybody else seeing this?
