Gatling Runtime Exception from Jenkins :java.io.IOException .. An existing connection was forcibly closed by the remote host

Gatling (Open-Source)
1

I Get the below exception while I run the Gatling(version 2.2.5) Test through a Jenkins Job at 5 TPS - rampUsersPerSec(0.1) to 5 during(5 minutes),constantUsersPerSec(5) during(15 minutes), the exception starts after 15 mins of test run.

However, I do not see this exception while the test runs at 0.2 TPS - rampUsersPerSec(0.1) to 0.2 during(5 minutes),constantUsersPerSec(0.2) during(15 minutes)

The Jenkins( version 2.66 ) runs on Windows 7(64-bit OS), with 4 GB RAM on Tomcat.

Will this be the limitation and cause for this exception? what’s triggering this, how do I get this resolved ? Is there any Gatling Jenkins Host(Load Generator) specification that I have to look for ?

Appreciate your inputs !

Thanks
