I switched to a 3.1-stable-990328 because of "Out of mbuf clusters -
adjust NMBCLUSTERS or increase maxusers!" messages with 3.1-stable-990311
that seemed to freeze the workstation. The 3.1-stable-990311 kernel was 
already configured with maxusers==128. So I increased it to 512 in the
3.1-stable-990328 version (my bi Pentium II has 512 Mo ram). And
instead of a stable kernel, I got something crashing every 5 minutes
or less.

I went back to maxusers==128 with 3.1-stable-990311 but given I got
"Out of mbuf clusters - adjust NMBCLUSTERS or increase maxusers!"
messages two or three times with that snapshot, I fear getting new
ones... 


What's the rationale between RAM and maxusers and SMP (if concerned) ?
