The machine I'using is running fbsd 2.1.
And here's my config setup.
The machine that is crashing is machine A on this diagram.
Machine A is a 486DX 33 with 8 meg of ram. An SMC elite card using the ed 
driver.

  sun       fbsd2.1   fbsd2.1   IPX
network <---> A <-----> B <-----> C

I have a network, and machine A connected via ethernet to a network of sun.
Manchine A is connected to machine B via a ppp link.
Machine B is connected to machine C via ethernet.
Machine A and B are FBSD 2.1, machine C is an IPX with solaris 2.5.
Machine A uses proxyarp  with machine B.
Machine B and C has a different set of IP addresses.

If I display an X application from the network to be displayed on machine 
B it works just fine.
If I display the same X application on machine C it will work for a 
couple of minutes before A reboots.
This behaviour is happening independantly from the application.
I sometimes get this message:
panic: free: too many frees
and a reboot

And I also got this message:

Fatal trap 12: page fault while in kernel mode
fault virtual address   = 0xf03b44e3
fault code              = supervisor read, page not present
instruction pointer     = 0x8:0xf019a2ec
code segment            = base 0x0, limit 0xfffff, type 0x1b
                        = DPL 0, pres 1, def32 1, gran 1
processor eflags        = interrupt enabled, resume, IOPL = 0
current process         = Idle
interrupt mask          = net tty 
panic: page fault
 


Any help will be really appreciated.
