don't worry, you are a great help!
Could you try the attached patch? I missed the fact that you are using
FASTROUTE in your setup. There is obviously a problem with it, but the
attached patch should work around that. The other LOR really is harmless
and rather an oversight in WITNESS: a LOR with a shared/read lock can't
cause a deadlock (unless there is also a LOR with the same lock in
exclusive mode). But this is rather complex to check and might not be
easily implemented in WITNESS.
Anyways - I believe this patch should work around your problem. Let us
know your findings - thanks.
