[JENKINS-27263] Checkout of svn:externals fails silently and intermittently

We have configurations based on svn:externals for our product. Sometimes (apparently at random) checkouts fail silently leading to files missing in the build tree.

Example of output during checkout (somewhat sanitized):

From what I can see the abnormalities are:

• after the first checkout of module5/dir_4/file_100.xml there is a slight delay (approx 3 seconds)


• At the end of the first checkout the line reporting at what revision we have reached is missing


• the files checked out into module5/dir4 in the first checkout seems to be removed again.

Without looking at the code or knowing anything I would guess that the subtask of checking out module-4 fails due to a network error or something but the main checkout task loses the error signal.

From what I can see the abnormalities are:




	
after the first checkout of module5/dir_4/file_100.xml there is a slight delay (approx 3 seconds)

	
At the end of the first checkout the line reporting at what revision we have reached is missing

	
the files checked out into module5/dir4 in the first checkout seems to be removed again.



Without looking at the code or knowing anything I would guess that the subtask of checking out module-4 fails due to a network error or something but the main checkout task loses the error signal.
