Gluster users - Sep 2009 - gluster brings down freebsd network interface

Hi All,

Our linux cluster uses a freebsd gateway, and it seems that starting a 
second glusterfs/glusterfsd instance (no matter as client or server 
listening on different port) on the linux machines tends to bring down 
the intel pro1000 NIC of the freebsd gateway.  It doesn't happen every 
time on each particular machine, but it almost always happens when I try 
to do it on each of our 66 machines.  I'm causing a lot of troubles to 
the cluster users by testing glusterfs and I'm wondering it someone on 
the list has an idea what's going on.

Strictly speaking, it might not be a bug of glusterfs, but we've been 
running the cluster for half a year and glusterfs is the only program to 
trigger the bug.

Thanks,

- Wei

What does bringing down the NIC mean? Any kernel logs? Programs are all 
working fine - no freezes - but just the network connectivity is out?
