Sorry, no bonus here.

tail /var/log/messages:
Dec 8 22:58:27 SERVER haproxy[25582]: Connect() failed for server XXX/YYY: local address already in use.

I have a few source config parameters set in a backend section. Let's say I have a 3 backends with source and 5 backends with source
There is no rule in which backend(source) this issue is triggered.

I've updated pf config to enable adaptive state timeout. I've raised mbuf clusters to a high value.

I believe i have no out-ot-mbuf issue here.

Some commands:

# netstat -m

# sysctl net.inet.ip.portrange

net.inet.ip.portrange.first: 1024
net.inet.ip.portrange.lowlast: 600
net.inet.ip.portrange.lowfirst: 1023

Not sure if this gives some clue here.

How can I help to track down this issue?

Best regards
