JR63191: DMTS64 CPU USAGE GOES TO NEAR 100% WHEN LAST SUB USING SHARED SCRAPE STOPS AND BEFORE ITS LOG PARSER AND READER STOP

APAR status

• Closed as program error.

Error description

• dmts64 CPU usage goes to near 100% when last subscription using
  Shared Scrape (SS) stops and before the SS log parser and SS
  log reader stop. Shared scrape keeps its log parser/reader
  running for a period of time after the last sub stops so if a
  subscription using SS immediately starts again we won't have to
  restart the log parser and reader. The length of time that SS
  waits to stop the log parser/reader is controlled by the system
  property sharedscrape_log_reader_parser_stopping_delay_seconds.
  By default, this is 600 seconds (10 minutes).
  

Local fix

• Set sharedscrape_log_reader_parser_stopping_delay_seconds to 0.
  If this is 0, SS stops its log reader and parser as soon as the
  last subscription using SS stops.

  * PROBLEM DESCRIPTION:                                         *
  * The log parser and log reader continue to run for several    *
  * minutes after the last subscription stops, as it is often    *
  * the case that subscriptions will start back up again within  *
  * several minutes.                                             *
