Hi

I've had a few replies (thanks), but the consensus is that it is not
possible to tell what my problem is without swapon -s output, so here it is
along with the other two again. Just to recap, the an application using
~240Mb of memory falls over.

> swapon -s
Swap partition /dev/disk/dsk0b (default swap):
     Allocated space: 98304 pages (768MB)
     In-use space: 23559 pages ( 23%)
     Free space: 74745 pages ( 76%)

Total swap allocation:
     Allocated space: 98304 pages (768.00MB)
     Reserved space: 32123 pages ( 32%)
     In-use space: 23559 pages ( 23%)
     Available space: 66181 pages ( 67%)
