In HEAD slapd/daemon.c, thanks to HEAD's multiple listener support:

slap_listener() protects emfile with slap_daemon[0 ].sd_mutex, but slapd_remove() protects it with slap_daemon[id].sd_mutex.

Maybe to compensate, slapd_remove() has code which checks if emfile is too big, but nothing checks if it is too small - which looks like slapd might never start listening again.

Simplest fix: add this to slapd_remove():

if (id) ldap_pvt_thread_mutex_<lock,unlock>( &slap_daemon[0].sd_mutex );

slap_daemon[0].sd_mutex looks quite contended that way, though. Maybe a separate emfile_mutex is better.
