Action Impersonating user - Sleep, Null and/or Connection timed out Exceptions

Issue/Introduction:

Running the "Get File Or Folder From Remote Agent" action while trying to impersonate another user returns the following error:

There are other messages after this Interrupt Exception. In particular it might be worth noting the following NullPointerException:

And finally it follows with some Exceptions we have seen before (covered here: https://ca-broadcom.wolkenservicedesk.com/external/article?articleId=37292), such as:

Cause:

The cause is still not clear at this time. But it may have something to do with the specific action (Get File Or Folder From Remote Agent).

Environment:

Release : 6.5

Component : CA RELEASE AUTOMATION RELEASE OPERATIONS CENTER

Resolution:

Recommendation is to open an issue if you're experiencing this problem. This might involve understanding the use case better and what the intended goal is, of using that action while impersonating another user, vs using a different action (like "Get File (SSH)").
