All the issues can only happen in out of memory situation. This can typically happen on some under-sized VMs or situations like that. If you know you're running at moderate loads with large amounts of free memory, you don't need to worry. By the way, these issues have been there for more than 5 years and were encountered for the first time now. They are not regressions, so there is no reason to hurry. That said, if you are used to build your own packages, it would obviously be better to include the latest fixes. The point about libpcre is that the libc's regex lib hangs on low memory conditions while libpcre handles the situation fine. This is the third issue of the list, for which there it no patch since the bug is outside haproxy. It is possible that recent a libc would handle the situation better though. Cheers, Willy
