We're been using MC pretty solid this past week but we are seeing random crashes. May happen one or more times a day or may go several days. Is this something I would turn the logging on, wait till it happens again and then make arrangements for someone at JR to review?
I would turn on logging, so you can capture the crash, yes. It won't hurt to know specifically what it was doing when it crashed.
Also, as Jim suggests, try to figure out more specifics about how and when the crash occurs. I'd also check your disk(s) for trouble, especially the disk that contains the Library, but also the disk(s) that contain your media files. Trying to import corrupt files and library access problems would be likely causes for full-on crashes.
That said, I
too have had a few odd crashes here and there over the past month or so, though this week's builds seem better. I can't say for sure though, because I'm just now recovering from a disk failure three weeks ago in my RAID, right while I was in the middle of swapping out the guts of my HTPC for an upgraded board. So, my problems may have been mostly to do with that, as they seem better now, and the disk problems are solved.
Still, though... MC has been "hiccuping" for me in Theater View (it happened tonight... Froze for maybe 30-45 seconds, and then "unstuck" itself). There are probably some gremlins in there.
