Wow this is very concerning, this bug was a regression in 2.6.38, and it looks like it was backported to their 2.6.32-32 kernel ! It was fixed in 2.6.38.8 if my memory serves me right. It seems rather strange they'd backport a patch that is known to break some products (haproxy and amavis are at least two identified victims), but it's possible they didn't notice the later fix. It would be nice to know what exact kernel their 2.6.32 is based on, and ideally what patches were applied on top of that. Regards, Willy
