I have the exact same problem only I thought I had it because I am
_NOT_ running 3.1,

% uname -a
FreeBSD cc942873-a.ewndsr1.nj.home.com 2.2.8-STABLE FreeBSD 2.2.8-STABLE #0: Sun Feb 28 22:14:50 EST 1999     cjc@cc942873-a.ewndsr1.nj.home.com:/usr/src/sys/compile/CC942873-A  i386

And just the recent bus errors,

% grep communicator /var/log/messages | tail

I moved to Netscape4 because Java would occasionally produce floating
point exceptions in Netscape3... but this is even less stable.

My hardware is also different from yours,

CPU: Pentium II (quarter-micron) (398.27-MHz 686-class CPU)
  Origin = "GenuineIntel"  Id = 0x651  Stepping=1
  Features=0x183f9ff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,SEP,MTRR,PGE,MCA,CMOV,<b16>,<b17>,MMX,<b24>>
real memory  = 134217728 (131072K bytes)
avail memory = 129613824 (126576K bytes)
Probing for devices on PCI bus 0:
chip0 <generic PCI bridge (vendor=8086 device=7190 subclass=0)> rev 2 on pci0:0:0
chip1 <generic PCI bridge (vendor=8086 device=7191 subclass=4)> rev 2 on pci0:1:0
chip2 <Intel 82371AB PCI-ISA bridge> rev 2 on pci0:7:0
chip3 <Intel 82371AB IDE interface> rev 1 on pci0:7:1
chip4 <Intel 82371AB USB interface> rev 1 int d irq 9 on pci0:7:2
chip5 <Intel 82371AB Power management controller> rev 2 on pci0:7:3

Which makes me wonder if it is Netscape at fault or something very
basic in the kernel.
