i am running a personal server and after nearly 26 days of uptime without any major problems last night at around ten pm. central time there was what i assume is a kernel panic. im running 5.2 RELEASE on a pentium 3 877 mhz. heres the output: (hopefully this is accurate i had to write this out by hand, if someone knows how to get the orignal output that would be nice)

syncing disks, buffers remaining... 1787 1787

and then it was crashed hard. i couldnt switch virtual terminals, i couldnt shut down, all i could do is press the power button. so thats my first problem, what happened? was it a kernel panic? or was it something different, and whatever it was, what caused it?

Yup, it was a kernel panic. Some process caused your panic, which is in this case swi1:net. Any idea what it is?

ok now onto the next problem. i was running my own mail server until recently as well, but i was getting beaten into the ground by spam. my /var/spool/postfix directory was 1.8 gigabytes. it was all spam i was bouncing from dynamic ips. none of it was getting to my accounts, but my server was getting clogged, since im running this off of adsl. im just wondering what i can do to stop this. the legitimate mail was not a problem at all. also this only started being a problem after a few weeks. as a temporary solution ive stopped postfix and deleted my entire spooled mail directory. however i would like a more permenant solution to these spammers attacking my server. right now postfix is bouncing all emails where the ips dont match the domain name.

Consider installing spamassassin?
