"Test of Means" Tool fails if run in two jobs on Server

When I run a workflow twice on the Server (version 2022.3), one of the jobs fails with error at "Test of Means" Tool;

Iteration #1: Tool #36: Tool #447: Get P-Value function (15): Iteration #3: Tool #8: Test of Means: Error in gzfile(file, mode) : cannot open the connection (ToolId: 408)

Workflow was Cancelled by Properties Setting (ToolId: 408)

I searched on the web for the message "Error in gzfile(file, mode) : cannot open the connection",

and it seems to be a general message when R cannot access to a file.

As another job completes successfully, I guess there may be some resource constraints in our R environment.

Could you advice if you have any suggestions to avoide this error?

For now, I would ask the users to avoid running the workflow at the same time.

But I want to have some permanent solution...
