I am running HAProxy version 1.5.2.
Using the stats GUI when I try to put a server in to MAINT mode it immediately reverts to being in service.
Message in the haproxy log looks like this:
Jan 23 10:01:07 Server blahblah is going DOWN for maintenance. 8 active and 1 backup servers left. 0 sessions active, 0 requeued, 0 remaining in queue.
Jan 23 10:01:07 Server blahblah is UP/READY (leaving forced maintenance).
Same procedure on HAProxy 1.6.2 works as expected. haproxy.conf looks the same on both versions so I suspect perhaps a problem with the version but I can’t find any specific notice about this. Anyone else run into this?
