Daniel, any idea? I thought at fuser, but it sucks to add psmisc to RDEPEND just for that... dragonheart@gentoo.org 2008-01-09 21:52:40 0000 inital very quick thoughts push a milter stop command down the socket? https://www.milter.org/developers/api/smfi_stop implement your own find on /proc for the socket though i'd try to look how other processes do it first. mrness@gentoo.org 2008-01-24 11:41:16 0000 Fixed in 2.4.3. I used fuser because psmisc is part of the system packages. rtpsld@ntsel.com 2008-01-24 16:40:54 0000 2.4.3 works for me and starts up cleanly now even with an old socket present. Thanks for the update.
