[mythtv-users] Threaded File Writer 'taking a long time'

[John Pilkington]

Over the past few days I've been seeing this quite often.  I don't 
remember seeing it before.  I first noticed it after an upgrade on 
Wednesday to mysql 5.5.28-1 on Fedora 16 x86_64, but I can't swear that 
it hadn't been happening before.  Recordings seem ok but I've seen 
instances of over 6 seconds.

The latest mysql changelog includes:
   - Export THR_KEY_mysys as a workaround for inadequate threading support
   Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=846602

That report seems to be Fedora-specific.  Has anyone else seen this?
