Hi All,
I recently upgraded to HAProxy dev-14 (and since this morning dev-15)
from dev11-ss-20120604. But, now we are experiencing uploads that are
'hanging'.
When uploading a file over HTTP the upload suddenly stalls. I cant get
my finger on it why. Sometimes it is right after the upload starts,
sometimes somewhere in the middle and (surprise, surprise!) sometimes
almost at the end. After a while the upload continues again and finishes
or stalls again. Uploads usually go with higher speeds 200-300mbit/s so
HAProxy CPU usage goes up a bit (10-15% cpu usage).
Is this a bug in HAProxy or is it my config? Downgrading to
dev11-ss-20120604 fixes the issue.
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
