If replying to an email please reply-to-all below > the original message. http://vds.kolivas.org/mailman/listinfo/ck Just out of curiosity, what's the slab? and what is the expected size of it? I just checked mine and it seems to eat some 304596 kB (2.6.14-ck4, soon 68d uptime). The only problems I've had recently is firefox crashing more than it should (but it could simply be me having a billion or so windows and tabs open, and it's the mozilla-firefox-bin-1.5-r2 from portage which is masked ~amd64, so it's probably just buggy - it dies with a segfault after beeing stuck at 100% CPU for a while, cant see any OOM-messages anywhere), other than that I've been able to both emerge stuff (nice'd though), download stuff and burn backups DVD's with out problems - simultaneously - and the system was still responsive :) - -- After all, if you are in school to study computer science, then a professor saying: "use this proprietary software to learn computer science" is the same as English professor handing you a copy of Shakespeare and saying: "use this book to learn Shakespeare without opening the book itself." -- Bradley Kuhn -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFDz9bVRbO4Br+gO6YRAoi+AJ474kaoue3QRausPgKKdYJtj1vmrwCdHcoE hqxwpAq5Hr2HUlIYmc5fXu0= =TgZJ -----END PGP SIGNATURE----- - : send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
