Sander, such a random behaviour cannot be caused by a config issue. So there is a bug, definitely. Maybe it's always been there and your config enlightens it, but there is no reason for a config to cause traffic pauses. Could you try to disable the splice options just to see ? And if that does not change anything, please also try to disable "option abortonclose". That will help us narrow the issue down. Anyway, I don't see anything wrong with your config. If you can easily reproduce this, I'd be interested in getting a network traffic capture on the machine running haproxy, I don't know if you can get send this. Thanks, Willy
