[Gluster-devel] io-threads segfault

[Kevan Benson]

Trying to start glusterfsd with this config causes a segfault.  Removing 
io-threads sections results in a running config.  Looks like an infinite 
loop of some sort.

volume ns
        type storage/posix
        option directory /data/graphita/glustertest/namespace
end-volume

volume master-raw
        type storage/posix
        option directory /data/graphita/glustertest/share
end-volume

volume master-single
        type features/posix-locks
        subvolumes master-raw
end-volume

volume master
           type performance/io-threads
           option thread-count 8
           option cache-size 64MB
           subvolumes master
end-volume

volume slave-raw
        type storage/posix
        option directory /data/graphita/glustertest/afr
end-volume

volume slave-single
        type features/posix-locks
        subvolumes slave-raw
end-volume

volume slave
           type performance/io-threads
           option thread-count 8
           option cache-size 64MB
           subvolumes slave
end-volume

volume server
        type protocol/server
        option transport-type tcp/server
        option listen-port 6996
        subvolumes ns master slave
        option auth.ip.ns.allow 172.16.1.*
        option auth.ip.master.allow 172.16.1.*
        option auth.ip.slave.allow 172.16.1.*
end-volume

volume trace
        type debug/trace
        subvolumes server
        option debug on
end-volume

Here's the backtrace.

This continues on, I haven't had the patience to find the end.
