delay(due duration in milliseconds) when resources are low

[Hummelbeine]

Hi everyone,

how does delay with a duration in milliseconds behave, when the system resources are low?

I'm asking, because I'm supporting an application that uses a library for OIDC and this library has an automatic token refresh and this refresh - from time to time - is triggered too late. The consequences are REST calls resulting in a 401.

"Too late" in the worst case I have seen means, that a delay of 4m30s did not result in a token refresh after more than 7 minutes.

The library has a calculation for the delay, but it is quite simple. So I have no explanation for this behavior, also because it seems to be more like random.

I would be grateful for any ideas.
