hastctl hang

[Daisuke Aoyama]

Hello,

I'm trying to integrate HAST to NAS4Free (FreeBSD 9.1-RC3).
Now I have created version 9.1.0.1.531.
http://sourceforge.net/projects/nas4free/files/NAS4Free-9.1.0.1/9.1.0.1.531/

Basic CARP + HAST + iSCSI target setup can be done, but very frequently I 
get hastctl hang when called:

/sbin/hastctl status
/sbin/hastctl dump

Is it better for this method not to call from a script?
or somthing wrong to use it?
Also, I don't know how to detect an error of writing to local device from 
hastd.
Does anyone know about it?

Thanks,
Daisuke Aoyama
