I have used fw ctl pstat command.
It says about 3Mbytes have been allocaated into FW-1's kernel memory
and most of it is still available.
However looking at the way Solaris works, it appears that the size of
freelist as found from vmstat and sar -r will apear to shrink to a very
small value, determined by lotsfree. In our case we have used the
default which is 1/64 of the RAM i.e. 2Mbytyes. The problem usually
starts when the freelist attains the value of around 2Mbytes.
I was wondering whether increasing lostsfree (making it bigger that
3Mbytes)would stop the machine hang. Has it been tried?
