Error while calling OnBeginRequest on WorkflowTransactionContext.

Hello Guys,

I have a few workflows which sends emails to users if certain conditions are met. However, many of the workflows are failing with the following error:

Would this be related to the CRM Async server? I checked the source code and there is no OnBeginRequest methods. 


Error Message:

    The issue was resolved by restarting the async server.

    Did you ever solve this problem?

    I am not a CRM developer myself, but we get this error a lot in the company I am working.

    We do not have email set up in our solution, but we use the async services a lot.

    Same Issue only with the build-in SLA workflow
