Hi list, I'm having a strange problem with haproxy 1.3.24, when the server gets more connections. Load is still ok by then (about 0.5), througput is about 50-100MBit.
Right now, everything is fine, I'm seeing: Server connection states (it also runs a squid, which is not used for this domain): 92 CLOSE_WAIT 21 CLOSING 3315 ESTABLISHED 86 FIN_WAIT1 171 FIN_WAIT2 60 LAST_ACK 34 LISTEN 99 SYN_RECV 1 SYN_SENT 9532 TIME_WAIT Port 8085 (haproxy-frontend) only: ESTABLISHED 1544 FIN_WAIT1 16 FIN_WAIT2 141 LAST_ACK 59 SYN_RECV 44 SYN_SENT 0 TIME_WAIT 1101 CLOSE_WAIT 1 CLOSING 0 It seems that somewhere over 2000 and between 4500 established connections, the problems start; I've not been able to determine the exact number, as I've changed the NAT to the server directly - it could handle the ~6600 connections without problems. When I was querying a server through haproxy (on the haproxy itself), I saw this huge lag: 1.) time printf "GET / HTTP/1.1\r\nhost: www.foo.de\r\nConnection: close\r\nCookie: -\r\n\r\n" | nc -v 192.168.92.11 8085 &>/dev/null real 0m19.976s user 0m0.000s sys 0m0.008s And at the same time, I queried the server directly, from the server running haproxy again: 2.) time printf "GET / HTTP/1.1\r\nhost: www.foo.de\r\nConnection: close\r\nCookie: -\r\n\r\n" | nc -v 192.168.70.43 80 &>/dev/null real 0m0.049s user 0m0.000s sys 0m0.004s Nr. 1.) always had the lag, Nr. 2.) was always slow, but it seemed to get slower, the more connections were open.. After switching the NAT from haproxy to the host directly, the query times are in the range of #2 again. It seems, that after a specific limit is reached by haproxy, the connections get slower and slower. It might also be a linux kernel setting but, any hint would be much appreciated...
