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.

On 2nd thought - I don't see how the outcome you describe can occur. If emfile is non-zero, the list of listeners will be checked for a listener with non-zero mute status. If any are found, one is guaranteed to be unmuted. If none are found, emfile will be zeroed.

In no case will slapd fail to unmute a listener.
