Surely not. There are at least kernel level limits, if memory serves me
right they aren't reported through ulimit on linux. I don't use linux so
expect not to much help here.

FUD. You are using qmail-ldap I might guess. It closes the connections fine.
Works fine with OpenLDAP and iPlanet Directory server. Looks more like IBM's
LDAP server does something wrong here. You might have more look using the
OpenLDAP client libraries instead of IBM ones (or vice versa, try it).

Use a working LDAP server.
Really looks like you are hitting ressource limits. Check ulimit -a for the
user qmails. And check the kernel ressource limits, defaults to 512
processes and file descriptors if memory serves me right.

Unix is very simple, but it takes a genius to understand the simplicity.
