OK,
very interesting, but no solution so far for us. We are running a HP machine 
with smart array with battery backed write cache (FBWC) and afaik caches on the 
(Intel) network adaptors too (runned with xen and NetBSD as Linux guests on it 
- only the NetBSDs are affected by the no  buf, no mbuf,  no rx buf 
"phenomena").

Disabeling the FBWC would usually be not a real option for production as this 
could hardly bring down the machine performance. Does anyone have any idea how 
to solve or "workaround" this "effect" or "bug" in NetBSD?

Is it possible that network adaptor caches or similiar have the same "effect"?

Many thanks and best regards,


Niels.
