Thanks to John for working on it. I got the problem to go away last week with a make world, but today's make world has brought the problem back. I am beginning to suspect that the problem is related to the way the system boots, or the order that the boot happens. The box that sig 11's has the older rc setup without the sysconfig. If I manually start things without the automatic rc I can get the system to sort of run ok. If I do the automatic startup then you can't even log in. I did the shared library ldconfig last. Hopefully I am not on another wild goose chase, but it looks like the sequence of bootstrap operations, and the kinds of things which are done have some effect on the sig 11 issue. *BTW this is a box that has the dma problem and must use bounce buffers* Could the clustering be broken on a box that needs bounce buffers? How about a wrap around condition at the boundary? (Just blue skying here) When I play with the order of starting things the sig 11's do not occur. I'm posting this in the hopes that it might give John that magic "oh yeah!!". I will play with this some more tommorrow. Regards, Mark Hittinger bugs@win.net
