A process in D state means the process is waiting in the kernel for something. The only thing I can see is that your kernel is very ill, because haproxy only does non-blocking accesses, so I think that if you run "dmesg", you'd see some odd messages. Most likely you're on a deadlock inside the kernel. Check your version and try to update it from your distro's repository. And from your description, I think you'll have to reboot anyway to get rid of that. Willy
