Emmanuel Lecharny commented on DIRSERVER-926:
---------------------------------------------

The problem with this issue is that nobody knows how to fix it !!!

I have set mly TCP stack to shutdwon connexions after 5 seconds to limit the impact (because I'm launching the server several times a day, this is really a burden for me).

If anyone has a better idea...

> Shutting down ADS leaves all existing connections in FIN_WAIT1. This isn't a problem.
> However, when starting up ADS again any previous connection still in FIN_WAIT1 will prevent ADS from starting.
> The only workaround is to wait until all FIN_WAIT1 connections timeout and get closed by the OS.
