Open a ticket for this. Include the full
"mythbackend -v channel,record,siparser" log for the recording.
The log you posted was cut off before the important part. Please
note in the ticket that you are using the patch from #3409, it
may take a little while before I have time to look at this. You
might also want to follow the mythtv-multirec branch as it may
resolve your issue, but it isn't ready for production use yet.
