The kernel's out of file handles. Go to /proc/sys/kernel and look at
"file-max" as compared to "file-nr" as well as "inode-max" compared to
"inode-nr". I think "nr" is the number currently in use... but I could
swear I've seen it go higher than "max".
Anyway, the solution is just to put larger numbers in the "max" files. In
my /etc/init.d, I've got a file called "setmaxfiles.sh" that contains:
echo "4096" > /proc/sys/kernel/file-max
echo "12288" > /proc/sys/kernel/inode-max
Then, I made a symlink to it from /etc/rcS.d/S37setmaxfiles.sh so that it
will update the kernel structures every time it boots (as it goes through
single-user mode).
