for a sun3 I could think of the kva being very limited to be a problem,

  could be anything most likely something port specific.
  can you get some back traces and a dmesg?

Sure thing. At the point of the 'ps' in the previous email, the system is completely wedged (even the screen session isn't responding), which is a bit worse than usual. bt and dmesg are below:

db> bt
zs_abort(0) + 6
zstty_stint(e32fdcc,0) + 8a
zsc_intr_hard(e32fdc0) + a8
zshard(e32fdc0) + c
isr_autovec(0,1,e00457a,e303800,20000e00) + 6e
m68k_compat_13_sigreturn13_stub(e305b80) + 68
lwp_trampoline() + e

db> dmesg
