title: KSqlDB : TopicAuthorizationException : Not Authorized to access topic [default_ksql_processing_log]
body: <p>Getting Unhandled exception caught in kstreams thread (CTAS_ query) with TopicAuthorizationException&quot; Not authorized to access topics : [default_ksql_processing_log]</p>
  <p>I am unable to understand what's causing on the same Kstream thread with topicauthorization, as
  default_ksql_processing_log is internal topic to KsqlDb.</p>
  <p>Please let us know if anyone facing this issue.</p>
  <p>I noticed when exception was caught the query attempted to restart, however data did not flow through. It worked only upon KsqlServer restart. Its happening frequently now.</p>
