For this, you need to set ulimit -c unlimited before starting haproxy and to disable user, group and chroot settings in the global section. I really understand it can be too much for you depending on your usage. If you could send me your config in private (without sensible info such as stats password), it would immensely help. BTW, if you cannot get a core but you have gdb on the machine, attaching gdb to the running process is another solution : # gdb attach haproxy_pid cont Continuing Then wait for gdb to return to prompt (indicating a crash) then please do : bt then you can send the output. Then you can exit with quit and restart the process. Thanks very much for reporting this, we'll do our best to get it fixed! Willy

I really understand it can be too much for you depending on your usage. Of course we are using it in production ;-) But I do have a fail-over situation so I think I dare running it again. It can take some time before crashing. If you could send me your config in private (without sensible info such as stats password), it would immensely help. Will do. Do you care which snapshot I run?

It can take some time before crashing. OK, so be careful anyway! If you could send me your config in private (without sensible info such as stats password), it would immensely help. Will do. Do you care which snapshot I run? Ideally the first one which exhibited the issue. BTW, do you know which most recent one you used without the issue ? Eg: do you know if 20120306 has the same issue ? Thanks a lot for your help, Willy

Eg: do you know if 20120306 has the same issue ? I'm currently running 20120207 which doesn't give me any problems. I upgraded straight to 20120310. Sander

Hey, I guess Willy would be keen to get the core dump and the haproxy binary with its configuration. You should try to reach him directly. cheers On Mon, Mar 12, 2012 at 4:03 PM, Sander Klein roe...@roedie.nl wrote: Hi, today I've experienced 3 crashes on 2 servers with haproxy. I've never had any before so I thought I would just put a note up here. 20120310 crashed with: Server 1 haproxy[3065] general protection ip:452ddf sp:7fff02906808 error:0 in haproxy[40+6e000] Server 2 haproxy[30329]: segfault at a22312e314e ip 00452db4 sp 7fff0553dbb8 error 4 in haproxy[40+6e000] 20120311 crashed with: Server 1 haproxy[30497]: segfault at a223156 ip 00452def sp 7fff343786c8 error 4 in haproxy[40+6e000] I know they are snapshots, but since none of the snapshot ever crashed on me before I thought it was worth noticing. Maybe it's already a known issue or it might be a new bug Greets, Sander
