It seems I have a hanging test in 3.15 as well

That's scanIoTest, which has had problems on various architectures and
was completely rewritten by Michael for the 3.16 branch in 2015. His
3.16 version probably won't back-port easily to 3.15 though, it uses
some 3.16-only infrastructure IIRC. If it's causing problems you might
want to just disable that test; I'm not sure what else to recommend.

Most of the time it works. In particular when I had re-run the tests

manually without even re-compiling, there were no problems. Only last

week it was hanging for 3 days once until I aborted it.

Thus I was suspecting some interference like two tests trying to use the

same port at the same time.

If I am running the tests for different EPICS versions on the same
Jenkins server, can they destructively interfere if the tests happen to
run at the same time? In that case I better change the Jenkins
configuration to use only 1 worker.

They shouldn't do, although you might want to set EPICS_CA_ADDR_LIST to
localhost and EPICS_CA_AUTO_ADDR_LIST to NO just in case. I usually run
the tests in parallel (make -j4 tapfiles) with no problems, but I'm not
running tests on multiple host-arch's on the same CPU.

I use the different workers to run 3.14, 3.15, 3.16, and 7 in parallel.

I do not use 'make -j' because that makes the output in the console log

more readable. Thus I do not suspect a problem with multiple host archs

but with multiple EPICS versions running at the same time.

I did not know about the "tapfiles" target and even now that you mention

it I cannot find documentation about it. I was running "make runtests"

but found that Jenkins cannot find failed tests this way. What should I

use instead?
