 	I tried to reproduce your problem with a -current SMP kernel from
 October 26th.  I ran two processes simultaneously for about 20 minutes or
 so without problems.
 
 	Try upgrading your kernel to something current, and see if that
 makes any difference.
 
 	In case it matters, I'm running:
 
 ASUS P/I-P65UP5 w/ C-P6ND cpu card with 2 Pentium Pro 200's (256K cache)
 128MB parity RAM
