Description Alexandr Shutko 2000-11-25 11:10:01 UTC 
Fatal trap 12: page fault while in kernel mode

Fault virtual address       = 0x20
Fault code                  = supervisor read, page not present
Instruction pointer         = 0x8:0xc01b027d
Stack pointer               = 0x10:0xccd27f6c
Frame pointer               = 0x10:0xccd27f78
Code segment                = base rx0, limit 0xffff, type 0x1b
                            = DP10, pres 1, def 32 1, gran 1

Processor flags             = interrupt enabled, resume, IOPL=0
Current process             = 328 (dnetc)
Interrupt mask
kernel: type 12 trap, code = 0

Stopped at tcp_timer_persist+0xad : movl 0x20(%ebx), %eax

Fix: 

unknown
How-To-Repeat: I can't said.. :(
We have socks5, squid, apache, inn, samba, postgres, icq-server, dnetc
on this machine - there are many open sockets (but number of mbufs is enought)

There have been numerous improvements in the code since 
4.0-Release. Can you try upgrading to 4.2-Release, or 
4.2-Stable and let us know how it goes? There is upgrading
