Error ZFS-8000-8A on 9.1 under VMware

hi,

I face weird situation ... may somebody advice, please?

Under VMware ESX 4.1.2 two FreeBSD-9.1-amd64-on-ZFS boxes were set.
on both of them open-vm-tools are installed

after some time of correct functionality, I'm getting error ZFS-8000-8A
on both of the boxes ...

after corrupted files removal and `zpool clean' no errors reported by
`zpool scrub'

than I was trying to svn stable and re-build/install world to be sure
all OS stuff is not corrupted, but while buildworld, build/installkernel
went well, installworld fails with different for both boxes errors 
"install: ...: Input/output error"

and in dmesg output is nothing related to the issue

the same was happening when I was installing FreeBSD on UFS before ...

is there some special configuration issues for FreeBSD on ZFS under VM?
