On Dockerized clusters that share zLMDB databases, eg for persistent cookie stores, when a cluster boots up it sometimes fails with lmdb.LockError
lmdb.LockError
https://gist.github.com/oberstet/fdebff3a9102e614b00c77f3d9757cff
Crucially: I never saw that on non-Dockerized clusters
However, in any case, this code seems to be sth we can and should improve https://github.com/crossbario/zlmdb/blob/2ebd65a51e0ba48fb72a354bbb72591d3d27d8e4/zlmdb/_database.py#L337
Plus, try to understand what's going on. Eg what exactly does Docker change in terms of Posix filesystem semantics?
We should also test with "NFS" in the mix .. that is, a concrete NFS implementation such as Linux and AWS EFS
