netbsd-8 crash

[6bone%6bone.informatik.uni-leipzig.de@localhost]

Hello,

With high CPU load netbsd-8 crashes from time to time. The crashinfo is 
not written correctly in every case. Eg crashinfo 8.

-rw-------  1 root  wheel  614974272 Aug  3 08:59 netbsd.8.core.gz
-rw-------  1 root  wheel          0 Aug  3 08:59 netbsd.8.gz
-rw-------  1 root  wheel  755472452 Aug  4 10:28 netbsd.9.core.gz
-rw-------  1 root  wheel     756718 Aug  4 10:28 netbsd.9.gz

netbsd.8.gz has 0 bytes, an analysis of netbsd.8.core.gz is not possible:
