pg.delayedRefresher.
CloudStreams cannot query for updates or receive deployed services until Integration Server is running. If Integration Server is not yet fully operational when CloudStreams starts, a delayed refresh helper is used to wait for Integration Server. This helper will periodically check on Integration Server's status.
pg.delayedRefresher.napMillis
Specifies the amount of time (in milliseconds) the delayed refresher helper waits before checking to see whether Integration Server is running. The default is 500.
