Hello,
I downloaded pre6 today and compiled it. glusterfsd starts up
successfully,
but if I connect to the socket then disconnect, it segfaults. It does this
every time. The server never segfaulted with pre5 on the same
configuration,
though my clients did at random times after heavy load inside
write-behind.
Hope this report helps:
Distro is CentOS 5 - stock kernel, latest yum updates, everything included
in installation.

glusterfs downloaded, untarred and built like so:
./configure --prefix=/usr

interfaces
subvolumes test_ko test_op
option auth.ip.test_op.allow * # Allow access to "brick" volume
option auth.ip.test_ko.allow * # Allow access to "brick" volume
end-volume
To produce the segfault, I simply telnet to the port and immediately
disconnect. Dumps every time:
telnet 192.168.2.5 6996
