What is the value of the "nsslapd-maxdescriptors" attribute on cn=config?

When this happens, the users cannot log in for long periods and get angry. Imagine that.
I do have this in a multi-master configuration with a second master, which is different
hardware and does not show this error.
I read the tuning page http://directory.fedora.redhat.com/wiki/Performance_Tuning#Linux
which recommends updating the filedescriptors limit like so:
echo "64000" > /proc/sys/fs/file-max
However mine is already well above that:
# cat /proc/sys/fs/file-max
How much higher should I be setting it? I am running RHEL 4 update 4, single Pentium III
1.4GHz processor, 1280MB of memory.
I don't have any settinsg in sysctl.conf or /etc/security/limites for soft/hard
limits, how do I tell what the defaults on soft/hard limits are?
