Too many open files

[Brent A Nelson <brent@xxxxxxxxxxxx>]

I put a 2-node GlusterFS mirror into use internally yesterday, as 
GlusterFS was looking pretty solid, and I rsynced a whole bunch of stuff 
to it.  Today, however, an ls on any of the three clients gives me:

ls: /backup: Too many open files

It looks like glusterfsd hit a limit.  Is this a bug (glusterfs/glusterfsd 
forgetting to close files; essentially, a file descriptor leak), or do I 
just need to increase the limit somewhere?

Thanks,

Brent
