[mythtv-users] comm flagging hdpvr file while recording results in errors

[sp]

My backend is able to comm flag HDPVR recordings while they are still recording but it seems like the comm flagging routine is not as accurate compared to doing the comm flagging after the recording has finished. My backend it able to comm flag at a rate faster than the file is recorded (720p HDPVR recording is 60fps but the comments in the jobqueue table indicate that comm flagging fps is faster -- "84% Completed @ 61.2766 fps")  This results in multiple errors spewed in the mythbackend log:

I've verified the errors are in fact generated by the mythcommflag process by sending a SIGSTOP signal (errors cease to show up in log) and then a SIGCONT signal (errors start spewing again).  Is this a known issue? Is there some way to throttle the speed of the comm flagger so it does not continually run into these problems?

I'm running 0.22 + latest fixes.
