You have kallithea/your repositories on a filesystem not supporting flock?

Comment by Wise Kaa, on 2018-05-08 11:48

Yes, it is on NFS volume.

I have bypassed this with beaker.session.type = ext:database

I think you could have stayed at 'file' for beaker session type, but changing the beaker.cache.data_dir and/or beaker.cache.lock_dir to a local filessytem path. I actually think it would be a good idea to do that anyway, because NFS is generally much slower than local files, and these files would normally not need to be available remotely.

data_dir (optional, string)
    Used with any back-end that stores its data in physical files, such as the dbm or file-based back-ends.
    This path should be an absolute path to the directory that stores the files.
lock_dir (required, string)
    Used with every back-end, to coordinate locking. With caching, this lock file is used to ensure that
    multiple processes/threads aren’t attempting to re-create the same value at the same time (The Dog-Pile Effect)

I guess the idea with using NFS would be to run server instances on different machines. In that case, I think it would need data and lock dir on shared storage too.
