On ubuntu 14.04, 64 bit, using "Logitech Media Server Version: 7.9.0 -
1420550541 @ Wed Jan 7 04:04:59 UTC 2015" with Server Power Control
plugin v20141101.163656.
When I need to rescan my library I normally do this overnight (because
Custom Scans take several hours). I use the very useful Server Power
Control (SPC) plugin to ensure LMS is awake well before the scheduled
rescan start time, and to shut down when all is done. This has normally
worked well.
At some point in the last few months I started to notice that the server
log had crashes in it at shutdown time, and ubuntu was complaining about
crashes the next morning. An example of such a crash reported on the
log is shown below.
To cut quite a long story short, with many different tests, I think I
have managed to fix it by changing the shutdown command in SPC slightly,
from
Code:
--------------------
sudo /sbin/shutdown -h now
--------------------
to
Code:
--------------------
sudo /sbin/shutdown -h now &
--------------------
The idea being that maybe SPC was blocking LMS (not just
squeezeboxserver_safe) from shutting down properly, and the trailing "&"
would allow SPC to relinquish control to let LMS shut down.
Has anyone else had this problem, or is able to shed light on the log
entry? (Sometimes the crash log seems to suggest the scan hasn't
finished, but it has. I repeated the process during the day is several
different ways, and the scan was definitely done (I also tried stopping
including the Custom Scan and manually ran the SPC shutdown command and
still got a crash).
