I'm seeing this as well, for me I *think* it's related to the fact
that I can no longer mount the gluster share, and I get the log
message about:
[2011-01-31 15:22:09.733051] E
[client-handshake.c:1067:client_query_portmap_cbk]
bhl-volume-client-98: failed to get the port number for remote
subvolume

but I'm not sure, I just sub'd a email to the list, if I find an
answer I'll pass it on!
