[rules-dev] Guvnor-5.5.0.Final : Continuously Throws "Connection reset" exception

Hi, We have an application running on Drools-5.5.0.Final. We are unexpectedly getting the following exception continuously. After the occurrence of this exception there is no impact on the application but sometimes application complains for "Unexpected Process Definition Exception" but that is rear. We need to resolve this issue before going live, still if the below exception has no harm. Can anyone help in this regard as what might be the issue. 07:06:46,745 INFO [org.drools.guvnor.server.security.SecurityServiceImpl] (http--0.0.0.0-8080-8) Logging in user [admin] 07:06:46,748 INFO
