NetBSD VM crashing with 16M, NOT with 14.5M!

[Chun Tham <ctham%acs.ucalgary.ca@localhost>]

Hi there everyone...  I left a note a little while back describing a
problem with my A2000/GVP-040/16M hanging with the SCSI light continuously
on while swapping.  I've since found that using "gobsd MEMLIMIT=xxxx"
where the xxxx is setting the memory to 14.5M makes the system as stable
as rock!

Everytime I go beyond the 14.5M limit to 15->16M the system becomes very
flaky when swapping again...  I've found this a problem in 1.1 and now 1.2
of NetBSD.  Is the VM subsystem running out of table space and memory is
getting trashed or something!?  Are there any config items / #include file
changes I can play around with and recompile with that could make a
difference? 


Regards,

PS: I know it's not a RAM problem since memory tests from AmigaDOS is 
fine...
