Yes, it is still a problem under the most recent 6 and 5 and CVS (what I presume is to be 7). The problem has never (to my knowledge) occurred under 4. While we can build and run our app on FreeBSD, every time (and yes every time) we put it under a real production load we get a kernel panic. Sadly, I can't produce a small or simple test case. After much effort, I still cannot get a kernel core. > Responsible-Changed-From-To: freebsd-bugs->remko > Responsible-Changed-By: remko > Responsible-Changed-When: Mon Dec 25 12:13:44 UTC 2006 > Responsible-Changed-Why: > grab the pr for feedback tracing. > > http://www.freebsd.org/cgi/query-pr.cgi?pr=76937 // Theo Schlossnagle // CTO -- http://www.omniti.com/~jesus/ // OmniTI Computer Consulting, Inc. -- http://www.omniti.com/
