Not > the underlying cause, just the "actual" cause (like a certain register > being a wrong value). Julian has, Doug Ambrisko has, I have, and, I think, Archie has. Note that the sig-11's we see occur after a lot of swap thrash not necessarily as a result of an out of memory condition. In general, when debugged, the process in question died from attempting to reference a page for which the mapping existed but for which the page itself did not (but by all rights should have). Someone kyped the page. Terry Lambert terry@lambert.org --- Any opinions in this posting are my own and not those of my present or previous employers.
