I have had two 3.1.1 client machines running  CentOS 5.2 crash with no indications in /var/log/messages, but with this stanza in /var/log/messages/etc-glusterfs-glusterd.vol.log:

[2011-04-27 11:12:00.350935] I [glusterd.c:275:init] management: Using /etc/glusterd as working directory

  5:     option transport.socket.keepalive-time 10
  6:     option transport.socket.keepalive-interval 2

I'm not running RDMA, I'm running TCP over 1Gb ethernet.

Volume created with:

gluster volume create pfs-ro1 replica 2 transport tcp <bricks ...>

Server info:

Repository revision: v3.1.3

Client info:
rpm -qa "gluster*"

Finally, this is (hopefully) the relevant section from the crashdump:
