[OpenIndiana-discuss] system hangs after upgrade

[Jacek Kotlarski]

Hi.

I installed OpenSolaris snv_134 on my old laptop Fujitsu-Siemens Amilo 
L7300 (single-core Celeron processor, 768 MB RAM). Only the text 
environment for testing pkgsrc.
After upgrading to the current OpenIndiana, the system hangs during 
intensive use disk, for example:

$ pfexec pkg unset-publisher opensolaris.org

or

$ dd if=/dev/zero of=file.out bs=1M count=1000


I think that perhaps the default settings ZFS require more memory ... 
How can I check this error? And how do I tune it?
