Hello,
I would like to report a segfault on HAProxy 2.0.11 ; this version has been
running fine for two months, and this morning starting segfaulting over and over.
Mitigation was performed by adding "no option http-use-htx" on 'defaults' block.
I know it's not the latest version :) I'll update to 2.0.13 this evening.
Program terminated with signal 11, Segmentation fault.

Config file is very long ... If needed, a coredump + binary can be sent on
private.
Hi,
A bug was fixed in 2.0.12 that could explain such of crashes. The upstream
commit id is eec7f8ac0 (or 0ed1e8963 in the 2.0 tree). It is related to the
GitHub issue #420.
But I don't know if it is the same bug because I don't know how it is possible
to apply an HTTP load-balancing algo on a TCP backend. I must take a look at
your configuration. You can send it to me in private. Maybe I'll found something
explaining your crashes.
Did you make any recent changes on HAproxy or your servers ? I'm surprised the
segaults appear spontaneously after 2 months without any problem.
