Vinum and SoftUpdates

[bsd at perimeter.co.za]

Hi folks. 

I have a few boxes which have recently begun to behave rather badly - 
frequent panics and lots of errors being spewed out during fsck on reboot.  
I note that these particular boxes have one thing in common - they have 
vinum devices which are also mounted with softupdates enabled. 

Is this OK?  I have not been able to find any mention of softupdates in the 
vinum man pages. 

Thanks for any pointers. 

Regards,
Patrick.
