Hi Paul,
I do not know about QGIS crashes but I was bitten by GeoPackages on
Network File systems.
We collected some hints regarding GeoPackage in the GDAL/OGR Trac Wiki
https://trac.osgeo.org/gdal/wiki/UserDocs/SQLite
Regarding writing to GeoPackages/SQLite we found the following:
The "[...] locking mechanism might not work correctly if the database
file is kept on an NFS filesystem. This is because fcntl() file locking
is broken on many NFS implementations. You should avoid putting SQLite
database files on NFS [...]."(SQLite FAQ)
cheers

Hi,
Is anyone else getting occasional deadlocks when using GeoPackages in
the Long Term Release of QGIS?
We are using them over a Windows network so there are multiple users
trying to access the same GeoPackage files. It all seems fine and two or
more can open the file to look at but when someone edits it you
sometimes hit a deadlock where none of the QGIS applications will shut
down.
The only resolution we have found is to physically switch off the
computers by holding the power button until the locks are released.
In theory I’d say that might be a pretty serious bug but I’m not sure
how to replicate the issue consistently and don’t want to raise a bug
ticket unless others can replicate the behaviour.
Thanks,
Paul
