Willy, I looked at the previous bug report here http://comments.gmane.org/gmane.comp.web.haproxy/5439 based on 2.6.38 and checked the ubuntu 2.6.32 kernel for the offending patch <http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=c191a836a908d1dd6b40c503741f91b914de3348> and I didn't see it applied to the kernel I'm using. Is there any other explanation, or some information I can find for you? Thanks, Jonathan
