Error shutting down Calcite server: No more data to read


#1

Hi, currently my mapd is taking a long time to stop it’s services after doing some load testing using jmeter. I tried reinstalling the application without formatting the server. But i’m still encountering the same problem and i found something weird when check mapd_server’s status. Please advise
