The messages seem to indicate that some process connects to nslcd but
closes the connection before the request can be read by nslcd.

This could be due to a timeout in the NSS or PAM module. The timeout
here is 10 seconds.

You should probably be able to solve this issue by increasing the
number of threads that nslcd uses and/or using (u)nscd to reduce the
number of lookups that nslcd has to perform.

If your LDAP searches are slow you could also see if adding indexes
server-side improves performance or perhaps tune your search filters to
return less entries (if your LDAP database is big).

Hope this helps,
