Re: [RDD] Rdairplay Crash at midnight after log chain
You could try enabling core dumps ("ulimit -c unlimited") and rerunning
rdairplay. The next time it crashes, it will leave a core dump that can be
examined with gdb (e.g. gdb /usr/bin/rdairplay core). You can then use
gdb's bt (backtrace) command to see what rdairplay was doing when it
crashed.
I seem to recall there being something funky with invalid timestamps that
would make qt complain...

[RDD] Rdairplay Crash at midnight after log chain
I've had this problem since the beginning. Can't remember if I get the exact
GP fault error or not.
In my case it crashes about half the time, but in spurts as in it will do it 3
or 4 nights in a row, then clear up for a few days, then do it again. I
haven't determined a pattern to it.
Years ago I configured a silence sense on it so it simply restarts rdairplay
(and starts it playing) once silence is detected. Since ripcd keeps running, I
can do all this with rml commands. On our main on-air machine that has a BT
ACS8.2 audio switcher, I use its silence sense to trigger the "fix it" macro.
On our backup machine (that lacks the switcher) I use the Jack Audio
"Silent_Jack" program. Both work perfectly, typically leaving about 15 seconds
of dead air as opposed to about 5 seconds of dead air normally when rdairplay
doesn't crash but is simply is being sluggish chaining logs.
Both machines use the same database (or at least snapshots of it), so I'm
guessing the problem originates from there. Both machines use Debian Linux but
typically are on completely different versions, our on-air machine is on a
fairly old version using the "If it ain't broke, don't fix it" concept. The
backup is typically the current Debian version. So maybe it could also be
something in Debian that has continued through 3 major versions of Debian.
