[Gluster-users] The continuing story ...

This is very similar to what I have seen many times (even back on
1.3), and have also commented on the list.

It seems that we have quite a few ACK's on this, or similar problems.

The only thing different in my scenario, is that the console doesn't
stay blank. When attempting to login I get the last login message, and
nothing more, no prompt ever. Also, I can see that other processes are
still listening on sockets etc.. so it seems like the kernel just
can't grab new FD's.

I too found the hang happens more easily if a downed node from a
replicate pair re-joins after some time.

Following suggestions that this is all kernel related, I have just
moved up to RHEL 5.4 in the hope that the new kernel will
help.

This fix stood out as potentially related for me:

We also have a broadcom network card, which had reports of hangs under
load, the kernel has a patch for that too.

If I still run into the hangs, I'll try xfs.

Thanks, Jeff.
