Open Stack

Hello,


I have got a nodejs application which is deployed on openstack provisioned resources. Somehow whenever my response has a large payload I am unable to receive the response to my web browser however I am able to print the response at the nodejs server end which is running in openstack. I am using LBAAS from neutron and use the IP of LBAAS to hit nodejs.


Scenario1: I send a request for an id which exist in DB. DB returns json data which is delivered to nodejs. However unable to send it to browser running on my host. I get a 504 error


Scenario2: I send a request for an id which DOES NOT exist in DB. This time I get back the json response all the way till browser.


To summarize all the communications are working fine, only difference between the 2 scenarios is payload size. I have been playing around with MTU on network as well as the compute node for br-tun and eth1 but till now have not succeeded . I am also trying out few things with tcpdump but nothing substantial I have found till now.


Need some help on how to debug this out.


Regards
Ashish
