OSF binary emulation problem

[Paul Gardner-Stephen]

Hi,

I am having problems running OSF 4.0 binaries under FreeBSD 5.0-RELEASE on an 
alpha personal workstation 500au:

~ {16:49} [70] :uname -a
FreeBSD cluebat 5.0-RELEASE-p6 FreeBSD 5.0-RELEASE-p6 #0: Mon Mar 24 18:11:18
 GMT 2003     root at cluebat:/usr/src/sys/alpha/compile/CLUEBAT  alpha

If I run almost anything I get:

~ {16:47} [65] :~/trace
exception system: exiting due to internal error: out of memory trying to allocate exception system resources
Abort (core dumped)

I am led to believe that this might be related to a problem with limits.  I 
however, using 'unlimit' has been in vain to date, eg:

~ {16:47} [67] :limits
Resource limits (current):
  cputime          infinity secs
  filesize         infinity kb
  datasize          1048576 kb
  stacksize           32768 kb
  coredumpsize-cur        0 kb
  memoryuse        infinity kb
  memorylocked     infinity kb
  maxprocesses         5547
  openfiles           11095
  sbsize           infinity bytes
  vmemoryuse       infinity kb
~ {16:49} [68] :unlimit
~ {16:49} [69] :~/trace
exception system: exiting due to internal error: out of memory trying to allocate exception system resources
Abort

Any suggestions would be greatly appreciated.

Paul.
