It is fairly easy to reproduce by doing a "ctlinnd newgroup". After that, a bunch of zeroes appears in the active file. I haven't bothered investigating the problem for lack of time because configuring INN to use read() just works and because I wasn't sure it was a FreeBSD problem, but I'm ready to do any testing I can to help fix this. -- Pierre.Beyssac@hsc.fr To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
