The thing is i'm not sure if it's vinum, I could also duplicate this on
another machine without vinum.. except I duplicated it differently..
Consider the following perl script:
#!/usr/bin/perl
for ( ; ; ) {
system("fetch http://www.web.site/index.html");
}
Of course, replacing the site with something else, but on this one box
(and the raid), it panic'd the box.. See if you can duplicate this on any
4.0/5.0 boxes you have, I have tried on both and it worked, however it
does not crash 3.x boxes..
Try your luck,
Jason DiCioccio
