You might try a list more focused on the LDAP applications and
other utilities you are using.   In particular, the nssldap@padl.com
list may be of assistance.

Not being familiar with Linux system admin tools (I don't use
Linux), I can only guess.  I'd guess the tools are protecting
the large number of applications which use the first character
to distinguish between a user name and user id.

I don't see such would have any significant impact on the
operation of slapd.   It's more likely you are running into
other problem(s) such as a file descriptor limit busy loop.
If that's your problem, then this experimental patch might
help:
