Hi,
I am trying to investigate a application hang where the communication from our app goes through haproxy to the backend database. I was hoping someone could shed some light on what the debug logging means…
During a normal request, I see this:
Aug 26 17:24:42 orion-lt-01-ibm-292 haproxy29: e[0;36;1mhaproxy.1 | e[0m0000033a:ft_postgresql.accept(0005)=0013 from [169.44.114.101:49006]
Aug 26 17:24:42 orion-lt-01-ibm-292 haproxy29: e[0;36;1mhaproxy.1 | e[0m0000033a:bk_db.srvcls[0013:0014]
Aug 26 17:24:42 orion-lt-01-ibm-292 haproxy29: e[0;36;1mhaproxy.1 | e[0m0000033a:bk_db.clicls[0013:0014]

But during the 3minute hang, I see this:
Aug 26 17:24:42 orion-lt-01-ibm-292 haproxy29: e[0;36;1mhaproxy.1 | e[0m0000033b:ft_postgresql.accept(0005)=0013 from [169.44.114.101:49060]

Can someone interpret this logging and let me know what haproxy is doing during this time?
Thanks!
