Since we don't see the OOM killer in action, I guess your memory is heavily fragmented. I guess this box has a long uptime? How much free RAM does "free -m" show? > Should I be worried? Memory allocation failure will lead to application failures.

Upgrading to 1.4.24 is important, there are several issues with 1.4.22. However, it will not fix this problem, as this is not a bug in haproxy. The problem mostly depends on your kernel. A quick fix is to reboot the box, which will make the problem go away for now. I suggest upgrading OS/kernel to a more recent version.
