[MapProxy] Error: No such file or directory: .lck

[BERÉNYI Attila]

Hi there,

We've been fighting the same error for the last couple of days, and it
turned out that the root cause is a data error (actually a character
encoding issue in the labels) - basically this means that the lock issue in
its own is not really helpful.

You've mentioned that the data is coming from an NFS share - maybe worth
checking the I/O rates?

Cheers,
Attila
