node crashing on 4 replicated-distributed cluster

Hi,

I've got troubles after few minutes of glusterfs operations.

I setup a 4-node replica 4 storage, with 2 bricks on every server:
# gluster volume create vms replica 4 transport tcp
192.168.7.1:/srv/vol1 192.168.7.2:/srv/vol1 192.168.7.3:/srv/vol1
192.168.7.4:/srv/vol1 192.168.7.1:/srv/vol2 192.168.7.2:/srv/vol2
192.168.7.3:/srv/vol2 192.168.7.4:/srv/vol2

I started copying files with rsync from node1, and after few minutes the
network traffic stalled.

Inspecting logs brick logs on node4, I've found many of:

[2010-12-24 15:58:50.247688] C [rpcsvc.c:1118:rpcsvc_notify] rpcsvc: got

On nfs.log of node1 (many, operations changing):

op(WRITE(13)) called at 2010-12-24 15:58:49.150707

Have you some idea?

Thanks.
