What kind of system is that? How much memory is installed? I'm able to hang an Ultra 60 with 256 MByte of main memory, simply by writing big files to a ZFS filesystem. The problem happens with both Solaris 10 6/2006 and Solaris Express snv_48. In my case there seems to be a problem with ZFS' ARC cache, which is not returning memory to the kernel, when free memory gets low. Instead, ZFS' ARC cache data structures keeps growing until the machine is running out of kernel memory. At this point the machine hangs, lots of kernel threads are waiting for free memory, and the box must be power cycled (Well, unpluging and re-connecting the type 5 keyboard works and gets me to the OBP, where I can force a system crashdump and reboot).
