Hi, I'm using haproxy on FreeBSD 9.1-amd64 inside a VMware VM.
I realized that when I have a situation where all servers in a backend are down, haproxy crashes: Jul 30 08:03:52 px2-bla kernel: pid 58816 (haproxy), uid 80: exited on signal 11 (core dumped) pkg info|grep haproxy haproxy-1.4.24 The Reliable, High Performance TCP/HTTP Load Balancer # ldd /usr/local/sbin/haproxy /usr/local/sbin/haproxy: libcrypt.so.5 => /lib/libcrypt.so.5 (0x8008c7000) libc.so.7 => /lib/libc.so.7 (0x800ae6000) I've got the following options: cat /usr/local/etc/poudriere.d/91amd64-options/net_haproxy/options # This file is auto-generated by 'make config'. # Options for haproxy-1.4.24 _OPTIONS_READ=haproxy-1.4.24 _FILE_COMPLETE_OPTIONS_LIST=PCRE DPCRE SPCRE OPTIONS_FILE_SET+=PCRE OPTIONS_FILE_UNSET+=DPCRE OPTIONS_FILE_SET+=SPCRE After some tinkering, I got a core-dump out of it: (px2-bla </root>) 0 # gdb /usr/local/sbin/haproxy /var/tmp/haproxy.58816 GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
