[Gluster-users] glusterfs segmentation fault in rdma mode

[Ben Turner]

This looks like there could be some some problem requesting / leaking / whatever memory but without looking at the core its tought to tell for sure.   Note:

/usr/lib64/libglusterfs.so.0(_gf_msg_backtrace_nomem+0x78)[0x7f95bc54e618]

Can you open up a bugzilla and get us the core file to review?
