Backend opening too many files?
Hi All,

I built and started running current master last night,
and it crashes within about 3hrs.

Saw a log on my console where I started it from saying

(process:12086): GLib-ERROR **: Creating pipes for GWakeup: Too many
open files

On the 2 times it's happened now i also have the following
in the dmesg log

[2172808.008729] traps: mythbackend[4453] trap int3 ip:7f6e210eba5b
sp:7f6b78c58af0 error:0
[2183801.777969] traps: mythbackend[23913] trap int3 ip:7f54ad8b6a5b
sp:7f5208457af0 error:0

I'm running 30d8a9637abf49d9a28eb64edeb8389a4b0b060e

Anyone else seeing such a thing?


Regards
Stuart

My fc25 build of the previous commit, v29-pre-397-g585f509, ran ok
yesterday for ~10 hours, with a 4 hr recording, with no apparent problems.
