Hello,
See if you have enough swap allocated. Increase them to at least 2 times 
the size of RAM.
(swap -l , swap -d , swap -a ; zfs create -V 16G /dev/zvol/dsk/rpool/swap)
Yes, it sounds so antiquate but I witnessed that not having enough swap 
can hinder normal functioning of the system and if applications are run 
outside of the zones without constrained resources , they can hog the 
whole system down. (Solaris/illumos does not over-commit RAM)

Then again, if your system wasn't behaving like that, you can try report 
your hardware, last osnet-incorporation and usenet-incorporation 
versions , where you can not see the bug happening and what 
BE/osnet/userland were first when it started to happen and report a bug 
report on bugs.openindiana.org .

If it just happened recently, you can quickly report osnet and userland 
versions from BE where it behaved right the last time (beadm mount 
bename /mnt ; pkg -R /mnt info) and your surrent osnet- and userland 
where it does not behave right.

If you haven't been updating for some time, to test, one can go through 
various osnet-incorporation and userland incorporation versions, by 
creating new BE with beadm create, select into it with beadm activate, 
reboot, pkg uninstall 'entire' incorporation, and then, by looking at 
the dates at: http://pkg.openindiana.org/hipster/ with Advanced search 
and install corresponding osnet and userland (and install-incorporation 
if needed) to see when was the first time bug appears and add that info 
in a bug report.
