Too many posts were made to a semaphore

FreeRangeDingo — Thu, 09 Jul 2020 19:28:50 GMT

I have two workflows -- BD Data Trade and FileUpload. The BD Data Trade workflow creates a bunch of Excel files and saves them to a shared drive. The FileUpload takes those files and uploads them to a Microsoft File Share site. The workflows work fine on my desktop. I need them to run from Gallery on a schedule. To make that happen, I have added an Event to BD Data Trade to "After Run Without Errors" run the FIleUpload workflow. I keep getting the error: Too many posts were made to a semaphore.

I have tried configuring/saving FileUpload to both a) a folder in our shared drive that Alteryx server has access to, as well as the folder location specified in Alteryx server in the system settings, control, persistance.

Error running Event #2: The external program "C:\Program Files\Alteryx\bin\AlteryxEngineCmd.exe" returned an error code: 1: Too many posts were made to a semaphore. (298).

I've also considered trying to create a bat file but the community links to posts on how to do this are broken. I have also tried chaining apps, but that doesn't work with the scheduler. I just want the completion of one workflow to trigger another workflow.

Thanks in advance.

Hi @FreeRangeDingo ,

A suggestion is for you to use the runner and the conditional runner from the great @MarqueeCrew. These tools give you the ability to run workflow after another.

Download the macro package: http://www.chaosreignswithin.com/p/macros.html

More about both tools: http://www.chaosreignswithin.com/2014/09/blog-macro-pack-2014-q3-release.html

A workaround also is for you to pack your second workflow inside a batch macro and to put it last in your first workflow.

Best,

Fernando Vizcaino

I wound up using a runner to start the main workflow and then a conditional runner to kick off the second one. I was never able to get the event to run the second workflow via command line.
