This afternoon around 2 or 3 pm, my backend lost all guide data. If I look at the Listings on MythWeb, every channel shows "NO DATA". This is on a system that has been running without problem for over 3 years and is still on 0.27.4/fixes. Everything else seems to be fine; live tv works, I can record the show I'm watching but all scheduled recordings disappeared. I can play back existing recordings with no problem. I'm assuming the problem will self-correct with the next download from Schedules Direct but that may be wishful thinking. If it doesn't I guess I'll have to find the proper Mythfilldatabase script to repopulate the database from Schedules Direct.

There was a short segment in the backend log that was out of the ordinary and that I hadn't seen before. I attached it. All the rest of the log contained routine entries that I see every time I look at a log.

Has anyone seen this before or have any idea what may have happened?

Thanks,

When you say short segment out of the ordinary, do you mean the "Expire autoexpire.cpp:641 (SendDeleteMessages) Expiring 0 MB for 1730 at 2017-04-23T21:42:48Z => Unknown" line?

I think that is just expiring a LiveTV entry where there is no guide data loaded so would be symptom rather than cause. The unknown is because there is no program title when there is no guide data.

Can you just run mythfilldatabase from the command line as your normal mythbackend user (probably mythtv) and does that fix it? Actually probably should be mythfilldatabase --dd-grab-all.

If you run from the command line the terminal output might provide some more clues about what is happening.

Otherwise maybe worth logging into your Schedules Direct account and confirming that all is correct there (I don't use Schedules Direct so don't know what "correct" might look like.)

There used to be an issue with old cache files that couldn't be deleted but I thought that got fixed long long time ago. Could try:
ls -ld /tmp/mythtv*
