haproxy tcp check results into a lot of error_transaction_end_before_headers

It might be possible to adjust haproxy checks by using special HEAD request check as explained on https://www.serverlab.ca/tutorials/linux/network-services/how-to-configure-haproxy-health-checks/

listen myapp2 0.0.0.0:8080
    mode http
    option httpchk HEAD /health_check.php HTTP/1.1\r\nHost:\ serverlab.com
    server node1 10.0.0.1:80 check fall 3 rise 2
    server node2 10.0.0.2:80 check fall 3 rise 2

Or we could replace the default squid logging daemon - to ignore such records and not to put them into access log at all.

For now we added the "apply ignore settings" in the realtime activity table too. Lets see if this is enough.

It seems this works good in 8.1 - if admin needs to only exclude haproxy checks - then this workaround might still be useful. Adding to known issues.
