I have been deployed prweb.war inside tomcat on windows . after starting tomcat server. i checked in manage apps . there prweb status is showing running . but if i tried to access localhost:8080/prweb its showing 503 error. I have attached log files below

Noted Error from Logs are 

1) Unable to create DSM service DATA-DECISION-SERVICE-STREAMSERVER DEFAULT

2) Service manager failed to startup

3) om.pega.pegarules.pub.PRRuntimeException: Startup Task: [INITIALIZE_STREAM_SERVICE] has failed after retries or with error

The above error comes only if i tried to deploy prweb.xml for pega infity 23 inside tomcat.

I am not facing any error while deploying prweb.xml for pega 8.8.3 inside tomcat

This is startup Error is only coming for pega Infinity 23
