This of course was a problem of processes still running and thus not 
relasing the file space. It took me a while to realize that.I removed


and did

	/usr/sbin/svcadm disable system-log
	/usr/sbin/svcadm enable system-log
	/usr/sbin/svcadm restart system-log

but saw no increase of available space in "df -h" for /var!? I finally 
discovered 15 or so processes like

     root 26263     1   0   Aug 17 ?           0:59 tail -f 

After killing all of them the space was available again.

Thanks a lot,
