Hi. I've been looking into why Xen VMs seem to cause problems for NYTProf tests, such as this example (from David Cantrell's system): http://www.nntp.perl.org/group/perl.cpan.testers/2009/11/msg6039168.html
I was digging through the results of
http://www.google.com/search?q=xen+clock+backwards
http://www.google.com/search?q=xen+gettimeofday+backwards
and came across this info
https://bugs.launchpad.net/xen/+bug/146924
https://bugzilla.redhat.com/show_bug.cgi?id=449346
http://rhn.redhat.com/errata/RHSA-2009-1243.html
I don't know much about Xen but the bottomline seems to be: upgrade.
Tim.
