Dean From: Dean Gaudet To: Mont Erickson Cc: apbugs@hyperreal.org Subject: Re: os-sunos/1840: Kernel data access exception / Server Resets Date: Thu, 19 Feb 1998 17:32:56 -0800 (PST) There's a patch from sun which fixes this I believe. It's definately a kernel thing, not an apache thing. If you search the bugdb for the other reports in the os-sunos category you'll find a bunch of other suggestions and maybe even the patchid.
