Missed scheduled trigger invocation

Hi Folks,

I’m seeing pretty wide-spread missed invocations for hourly scheduled trigger, as shown below for one of the installations in production for the past two weeks. Each data point is a 6-hour span, so I’d expect that they should all have 6 invocations. But only a handful are actually 6 and many are down to 2 invocations per 6 hours!

Any clue what’s happening? Any advice on anything we can do on the Forge app side?

Thanks!
