This is odd. When I start another VM, then the error changes to:
"There are insufficient CPU resources to complete the operation. Please contact the System Administrator.; majorErrorCode=500; minorErrorCode=INTERNAL_SERVER_ERROR; vendorSpecificErrorCode=null; (Workflow:Wait for a task / Throw exception (item5)#1)"
Of course there are CPU resources. If I power_off the VMs, then the workflow runs correctly.
Please I need your help.
Thanks,
Damián
