Public bug reported:
For the past few days, I've been getting a lot of errors from
clementine. Some errors are this:
pa_threaded_mainloop_new() failed
LibraryBackend: unable to open database file Unable to fetch row
Sometimes, it's a gstreamer error:
GStreamer-CRITICAL **: gstsystemclock: write control failed in
wakeup_async: 24:Too many open files
Both of those show up in GUI dialog boxes. Outputted to the console, I
see errors like this, repeated for dozens of directories in my Music
collection:
2:05:53.962 WARN unknown
QFileSystemWatcher: failed to add paths:
/home/(redacted)/Music/Nastasia, Nina & White, Jim
Then when you try to play music, either the database error from above
shows, the gstreamer error is shown in a dialog box, or the app just
exits.
There are two things I find resolve the problem.
1. Splitting my music collection in half and putting half in one
directory and half in another, then only using one directory at once.
Because this solves the problem, I know that no particular file is
tripping up clementine.
2. Disable the "Preferences -> Monitor the library for changes" resolves
the problem entirely, regardless of the size of my music collection.
I believe that Clementine is using QFileWatcher to watch changes to my
music collection, and now my music collection is large enough that this
behavior causes Clementine to run out of file handles.
