So it's really byte range locks that bite you. Can you take a network
trace of one client? It will reveal your data, it will be huge, but it
might provide valuable input for us to reproduce and eventually fix the
issue with brlocks for you in a proper way. "locking=no" is not a good
idea except for special use cases :-)
