This is a problem I have seen for a long long time and have actually brought it up on the list before. Xymon 4.3.21 Ubuntu 14.04LTS
The problem I have (in this instance) a warning which is to be repeated daily suddenly goes red and triggers a single alert but doesn't repeat again until the repeat time of the warning has passed.
From the notification.log: Tue Mar 28 05:31:28 2017 ServerA.disk (IP) disk_warn 1490697082 100 <- warning sets a repeat time of 1 day Tue Mar 28 05:53:32 2017 ServerA.disk (IP) disk_alert 1490698405 100 <- minutes later it goes red (red repeat time is 15 minutes but no further alerts are generated) Next alert comes out 1 day after the above warning: Wed Mar 29 05:31:31 2017 ServerA.disk (IP) disk_alert 1490783486 100 <- 1 day after previous warning. This should have been repeated every 15 minutes. Wed Mar 29 05:46:40 2017 ServerA.disk (IP) disk_alert 1490784394 100 <- now, the repeat time is 15 minutes ... <- and continues every 15 minutes.
This alert went a full 24 hours with only a single notification. :( I have seen this before (not always) where the repeat time in a warning overrides a follow up alert until the warning repeat time has expired.
