I have an FME workbench that performs change detection logic and outputs features using the Automations Writer. This workbench is triggered within an automation, and downstream workbenches receive their input from the Automation Writer output.

Most of the time, everything works as expected. However, on rare occasions, the workbench fails with the following error:

AUTOMATIONS Writer: FME Flow error: 'Blocking request exceeded 10s'
 

I would appreciate any suggestions or possible workarounds to prevent or handle this issue.

That's a new one for me. Is there anything else in the automation log?

Looking at the log snippet there my first guess is that features may be getting to the automation writer too far apart in time (more than 10 seconds). 

If that is the problem you could try and combat this by putting a FeatureHolder directly before the Automation Writer. This will collect all the features and then release them once there are no more features to process. All your features should hit the Automation Writer at the same time.

If this doesn't solve it then we'll need a bit more info.

How long does the workspace usually take to run?

Which version if FME is this?

Seconding Matts suggestion of a FeatureHolder.

My (limited) understanding of the Automation Writer is that it is asynchronous and as soon as a feature hits it, it triggers the next step of the Automation, so it would be expected that features could be a significant time apart - maybe that’s not the case?
