Internal Error(Check logs) - Play 1.2.x

I am working on PlayFramework 1.2.x version; everything works fine if I deploy my application on a single server, there are several web pages developed using the framework.

Working on a scalability perspective, I have created two instances and put it under a Server Load Balancer (SLB). But I am not able to access the underlying web pages due to the below error. both on https:// and http://


I have tried clearing the /tmp folder from the Linux VM’s.
Any help is appreciated, Thanks…
