I found that the user limits were by default 1024 and I could not set the
nsslapd-maxdescriptors higher than that, so I upped the default limits and changed
nsslapd-maxdescriptors to 2048. We'll see how that works out. Thanks Richard and
George!

The server sets this itself. So you have to set the value yourself.
See
http://www.redhat.com/docs/manuals/dir-server/pdf/ds71cli.pdf -
search for nsslapd-conntablesize and nsslapd-maxdescriptors

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.
