I rolled back to RC2, and no longer have this problem.
i don't see these error messages, and processes that were hanging
before are not hanging now?
I'm using single process AFR. should I split it out and try RC4, or
does it not seem logical that this should be a problem?

single process client/server.
which used to be the recommended method and now is not.
if I split those out, will that solve my problem?

Are you using any applications that hold POSIX fcntl locks? Try
running the server in debug mode --- then you can find out which files
are being locked/not unlocked, etc.
well, I'm sure I am, I've no idea really, there are some php
scripts which seem to hang and some python programs.
however, this problem only manifested itself when I upgraded to rc4
and the new fuse-2.7.4glfs11
so something must be significantly different about how those (or
that combination) handles locks.
Also, debug mode wont really solve the problem, cause knowing what
exact file is the problem, isn't going to help because that wont
really tell me how to prevent this from happening. Clearly one
side should get the lock and one should wait, rather than both
servers in the replicate pair just hanging on the same file?
in addition, ERROR mode logging should log enough related
information to know this stuff (this is an enhancement request :) )
