<div>Hello all,</div>
<div> </div>
<div> I've been a mythtv user for a few years. My configuration is a single system frontend/backend. Since it's inception I have been using realtime commercial flagging and it has worked very well. However, I recently updated my mythtv svn tree (to 17392 from an update 5/3/08) and every once in a while the system completely hangs. It hangs to the point where the magic Alt-SysRq-REISUB does not reboot it, no SSH, no three-fingered-salute, no nothing.</div>
<div> </div>
<div> I get nothing in my logs (FE, BE, syslog, messages, etc) and it appears to happen when recording and doing commercial detection. It froze three times over three days and I started to worry. I completely disabled commercial detection and it worked for two days straight so I decided to turn comflagging back on because the queue was huge. It detected all the commercials in the recorded shows and the next day while recording and comflagging it died again! So I turned off the realtime comflag option and it has been working for two days now without a hang.</div>
<div> </div>
<div> I thought maybe it was a memory issue so I sacrificed a few shows and ran memtest86 overnight; it completed 12 cycles and didn't report any errors. None of the information I have proves anything but so far it's looking like some update done in may to the comflagger is the culprit. Anyone have information that supports or debunks this theory? It's not a big loss to not have realtime comflagging but it was a cool geek thing to tout. :)</div>

<div class="gmail_quote">Well, it has been running for more than two weeks straight without issue since I have changed the comm-flagging to run after the recording completes (instead of simultaneously during recording). I guess it could be some sort of problem with reading and writing the file at the same time. At least my backend is stable again.</div>
