bdes: fwrite error at 8

[Lars Eggert]

Hi,

I'm doing encrypted nightly dumps over the network to an NFS file  
system, i.e., dump | bzip2 | bdes > nfs.

Since about a week ago, I see occasional errors from bdes ("bdes:  
fwrite error at 8"). Anyone have a hunch what's going on here? I'm  
wondering if this is something that started when I upgraded to 7.2- 
PRERELEASE...

Thanks,
Lars
