I am trying to build some workflows, but regardless of its complexity the workflow hangs with Status Reason: Waiting for Resources. Tried already to restart CRM services. Anyone has an ideea on how to fix this behavior?
Restart your ASYNC services.
The asynchronous services are on the CRM server, in the control panel - services.
Microsoft Dynamics CRM Asynchronous Processing Service
Sometimes the Asynchronous service can get stuck or consume lots of memory and then become very slow.
Hope this helps.

I did that and and it did not affect the workflow's status.
It is waiting for all records or only with some/particular record.
You can check details of Workflow (top left side).
What is your workflow doing?
So far I’ve discovered that Real-Time Workflows are working. Once i convert it to background workflow it's not working anymore (it is not called by the system).
So, this raises a question. I need to send 1 email notification once I activate a contract and I need to send 3 notifications before the contract expires. I plan to do 2 workflows: Activation Notification and Expiring Notification (90 days, 60 days, 30 days). These workflows should be Real-Time Workflows or Run in Background Workflows? What is recommended?
It should be background workflow.
1-Background workflows are generally recommended because:
2-They allow the system to apply them as resources on the server are available
3-Help maintain the best performance for everyone using the system
4-They are fine for most automation of business processes because the people using the system don’t need to be consciously aware that the process is running.
Use real-time workflow:
1-When a business process requires someone to immediately see the results of the process
For example, you want to set certain default values for a record the first time it is saved
Or you want to make sure that some records are not deleted
2-If you want the abilityto cancel an operation
When you have the message waiting for resources it tries to process all tasks and workflows. I don't know your environment looks like, but you can try to tweak the table "DeploymentProperties" in the MSCRM_Config table.
Update the fields:
AsyncItemsInMemoryHigh from the current value (most likely 20) to for example 200
AsyncItemsInMemoryLow from the current value (most likely 10) to for example 100
It enables the AsyncService to process more items in memory.
please do explain how to do that, facing same problem
Hi Marius, you have any update about it ?. I have the same problem, the only difference I using a workflow custom activity attach to workflow, is run perfect on sync mode, but hangs "Waiting for resources" in async
The workflows hangs with status reason waiting for resources/ InProgress/ Waiting /Pausing due to different issues like-
1. Many jobs are in waiting status.
2. AsyncOperationBase table become full due to many succeeded/canceled jobs occupied space.
3. Asynchronous processes settings are not proper.
4. The asynchronous workflows are not configured properly.
Very first step is to restart the Microsoft Dynamics CRM Asynchronous Processing Service. This might work in many cases.
