This solution is now in 4.25 patches and available with patch packages.

What now happens is that when CheckTimerInterval is set to 0, API 
failure sets the API status to failed as usually. When 
FailureBackoffTime, a new parameter, seconds have elapsed since the 
failure was detected, the API is considered to be working again.

In other words, this matches the behaviour quoted above with 
FailureBackoffTime being the configurable parameter for the number of 
seconds.

The default value of FailureBackoffTime is 60. If set to 0, then the API 
never remains in the failed state. Longer values avoid using the API, 
for example, when there's a need to access many different devices to 
troubleshoot timeout causes.

As always, feedback is welcome.

Thanks,
Heikki
