[ISS Support Case] Repeating Missed detection interval messages in SMC Historian - 20.1 SP1

Last updated: October 17th, 2025

Description

Warning shown on logger about 20 times per hour for missed detection interval. There are 3 different threads listed. This has been going on for awhile and the 2017 historian has some of these errors as well, but they are much less frequent (1-2 per hour) Warnings from logger shown below: 18413823 7/19/2022 10:50:45 AM 15824 5700 Warning aahEventSvc Main EventService: Missed detection interval [VA03YWVDB0100; D:\ADOBuild2\2\s\src\Event\aahEventSvc\PoolDetectorThrd.cpp; 323] 18413824 7/19/2022 10:53:30 AM 15824 15952 Warning aahEventSvc Main EventService: Missed detection interval [VA03YWVDB0100; D:\ADOBuild2\2\s\src\Event\aahEventSvc\PoolDetectorThrd.cpp; 323] 18413825 7/19/2022 10:55:46 AM 15824 15964 Warning aahEventSvc Main EventService: Missed detection interval [VA03YWVDB0100; D:\ADOBuild2\2\s\src\Event\aahEventSvc\PoolDetectorThrd.cpp; 323] Would this be 3 of the same event tags or could it be any event tag? There are 77 event tags in the historian. I work part time from the west coast, so email replies would be the best way to get in touch.
