The ITS doesn't really handle MIME messages very well.

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.

Alternatively, just skip the check entirely when id != 0. Which would mean that only closing a session on the first listener would ever trigger the other listeners to be unmuted. Doesn't seem so terrible; if slapd is actually out of descriptors one or two connections either way won't make a huge difference in service. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/
