Hi all,
we encounter problems from time to time while starting vbox instances
or running virtual boxes simply die for know obvious reason. For quite
a while I had no idea why, until other processes on this Solaris box
send out a "Virtual Memory exhausted" messages. This made be checking
swap space. I am used to the following:
-bash-3.00# swap -s
total: 177032k bytes allocated + 29072k reserved = 206104k used,
2195552k available
meaning almost nothing used and almost everything available. However,
on all machines that are running vbox sessions it's the opposite!?
bash-3.00$ swap -s
total: 19745968k bytes allocated + 2594724k reserved = 22340692k used,
727592k available
19GB allocated??

This prstat output shows that approximately 16GB of memory are in use.
But this machine has 64GB RAM. How can it be that this machine uses
22GB swap??
I did
zfs create -V 10gb rpool/swap2
/usr/sbin/swap -a /dev/zvol/dsk/rpool/swap2
and this seems to help for now, but I don't want a machine with 64GB
RAM to swap.
-bash-3.00# prtconf -v | grep Memory
Memory size: 65536 Megabytes
Any idea? What am I missing?
Thanks a lot,
Andreas
