Thanks, this will be helpful to find a good load balance as the systems are
running.

I was just thinking about how useful this would be, and will submit a patch
for it.

Dynamically change server maxconn possible?

[Daren Sefcik]

I am thinking the answer is no but figured I would ask just to make
sure...basically can I change individual server maxconn numbers on-the-fly
while haproxy is running or do I need to do a full restart to have them
take effect?

TIA...

It's not possible right now but given that we support dynamic maxconn,
I see no technical problem to implement it and I actually think it would
be a good idea to support this on the CLI, as "set maxconn server XXX"
just like we have "set maxconn frontend YYY".

If you (or anyone else) is interested in trying to implement it, I'm
willing to review the patch and help if any difficulty is faced.
