Hi.  I'm running 4.0_BETA2 on a SPARCserver 20, and while bzcat| 
tar xf'ing a large archive (pkgsrc-2007Q1 sources), saw:

sd0(esp0:0:1:0): unable to allocate ecb
sd0(esp0:0:1:0): adapter resource shortage

   On the console.  As I'm not doing much with the machine, other  
than the single heavy batch of disk I/O, it concerns me that I see an  
error like this.

   Is there anything I can tune to make this less likely?  Anything I  
can do to better understand the problem?  Thanks.

   I'm running GENERIC.MP (but on a single-processor system) build  
from netbsd-4 sources April 23, 2007.
