Dear folks,
Please let me try to get some responces about a funny symptom
about the Subject.

I am running a dual-xeon box, Iwill's DP400, with 4.6.2R.
While I was running dnetc for rc5-64 project till recently,
I observed frequent `segmentation error' when I ran compilers,
especially when I invoke `make' in /usr/src or /usr/ports/xxx/yyy.
This Signal-11 occurs when I was running dnetc on the box.
When I put kernel option CPU_ENABLE_SSE, its frequency decreased,
but still existed.

A funny thing is when I stop running dnetc, signal-11 does not
happen.
On uni-processor P4 system, this symptom has not happened.
It did not happen on Tiger-MPX, either.

My question is if anybody of you have experienced similar symptom
on their xeon dual boxes.
In advance, thank you for your attention.

best,
Yoriaki Fujimori
