I have a brick that crashed twice today, and another different brick 
that crashed just a while a go.

This is what I see in one of the brick logs:

And somewhere before these, there is also
[2012-06-08 15:05:07.512604] E [rdma.c:198:rdma_new_post] 
0-rpc-transport/rdma: memory registration failed

I have 48GB of memory on the system:

The server gluster versions is 3.2.6-1. I am using have both rdma 
clients and tcp clients over 10Gb/s network.

Any suggestion what I should look for?

Is there a way to just restart the brick, and not glusterd on the 
server? I have 8 bricks on the server.
