Re: kernel panic and postfix problems
ok, sorry for the late response. it (the kernel panic) happened again twice! i was backing up my friends laptop with rsync all three times the kernel panic occured. this leads me to believe that rsync is the cause of this panic. everytime swi1:net is the cause of the problem, only the stack pointer and some other pointers are different for the output. so someone who know more about kernel panics than me, why would rsync cause one? ok now back to postfix and spam. Jorn, how would spamassassin help my problem, the spam is not getting to any of my accounts, since postfix is bouncing the mail back before it ever reaches a user mailbox. although maybe spam assassin does something i was unaware of. if it does have some sort of black list feature or something else that can help me great. please enlighten me. and Bill, ill look into the greylist you talked about, it looks really helpful. my only question is will it significantly reduce the network traffic? right now my problem is not accepting the mail, its just that my personal server on dsl doesnt have the bandwidth to bounce all of these messages back. also does the grey listing have any advandtages to using a black list provided by spamhaus.org or something similar. thank you both for your help anthony philipp On Wed, 2 Jun 2004, Jorn Argelo wrote: Anthony Philipp wrote: hello, 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) Fatal trap 12: page fault while in kernel mode cpuid =0; apic id = 00 fault virtual address = 0x38 fault code = supervisor read, page not present instruction pointer = 0x8:0xc06bc08a stack pointer= 0x10:0xcb57098c frame pointer= 0x10:0xcb570a68 code segment = base 0x0, limit 0xf, type 0x1b = DPL 0, pres1, dres321, gran1 processor eflags = interrupt enabled, resume, 10pl=0 current process = 27 (swi1:net) trap number = 12 panic page fault cpuid=0; 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?
