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).
