nslcd does not cache DNS lookups, except if you use the DNS value for
the uri option. The hostname lookups are done by the OpenLDAP library
and libc, completely outside the scope of nslcd. If could be that the
information is cached there somehow.

In general, it is recommended to use an IP address to specify the LDAP
server if possible to avoid these kind of issues. The "No such process"
error is a bit weird though.
