Error 503 : Service Unavailable

Thanks for these pointers. I noticed that SIGTERM is generated when i restart all the services (after the APIs stop responding) .

About ssl issue - can that cause APIs to not respond. I am using http in my API calls…

Did anyone not have this issue at all ??

Really need some help as the DF APIs have just started behaving very randomly and stop responding almost everyday . I am having to restart all service to regain the resposnes (ctlscript restart)
