Re: OperatingLimit and MaxRuns in Taverna

[Simone Bnà <s....@cineca.it>]

Dear Taverna staff,

I've been told that Taverna queues the workflows that are triggered after reaching the maximum number of "operating" workflows (aka OperatingLimit) but not the runLimit.

What I noticed is instead that Taverna complains and return the following error:

http error status code 503; server too busy; try later please

Are there some configuration parameters that need to be changed in order to activate the workflow queue?

Best regards,

Simone.

There is a configuration file - see

Then it is queued.

It will run.
