Hello, I had the same problem after upgrading from 2.0.5 to 2.0.6. I ignored the mistake and rolled back. I thought the mistake was mine. I use the self compiled versions only privately.
The logs, config and build-script are in the attachment. HAProxy runs on a debian 9 VM cheers Michael Am 14.09.19 um 13:08 schrieb GARDAIS Ionel: > Hi, > > I've just upgraded to 2.0.6 and all server checks went erratic. > I had to disable checks for the servers to be reachable. > > The observed behavior was a flip-flap (but mostly down) of server > availability with L4TOUT when the server was considered unresponsive. > > Ionel > > >
