I am randomly getting HAProxy 502 errors when I send request to my backend via haproxy.I have put retry on 502.But still I get 502 errors.  
I have installed HAProxy on a Ubuntu 18.04 system with 4 cores.  
The following is the termination code I get from haproxy logs  
502 209 - - SH–  
0/0/0/-1/0 which correspond to %TR/%Tw/%Tc/%Tr/%Ta

The following is the configuration.
