Most times it runs totally okay but sometimes (not reproducable)=20 the process freezes with state "*inp" shown with "top". On no other operating system this problem occurs. (Linux 2.6.x and FreeBSD 6.2 and -Current)=20 When I googled for information I found this in the FAQ of unrealircd: http://www.unrealircd.com/faq.php#105 I assume the bug they refer to is also present in 5.5-Rls and that this is the cause of the random freezes. I asked the unreal developers if they know any more specifics but they didn't.=20 Does anyone know what "tcp socket bug" they are referring to? I'm not so familiar with the FreeBSD kernel(and debugging it etc.) The simplest solution is probably to upgrade to 6.2 but I'd prefer fixing t= he bug for 5.5.. (I forgot to mention that I formerly had 5.4-RLS installed and experienced = the same problem)=20 MfG, =09 Julian D. `alamar` Seifert -- =20 "Emacs is a nice operating system, but I prefer UNIX." - Tom Christiansen gpg fingerprint: 435D DDDA 251B 9D70 2F72 78E0 AA5F 11F4 A4ED 451E --HlL+5n6rz5pIUxbD Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFGyZMyql8R9KTtRR4RAnqGAKCVioPhY8449JHm1Trpao7V3PO2BgCfQ7H2 1DpjVnr6yOYioyzz9lnL57g= =RIvv -----END PGP SIGNATURE----- --HlL+5n6rz5pIUxbD--
