Dirk, 

 

What happens if you run that test manually? All EPICS unit tests can be run individually without using the test harness to see more details as the test proceeds. This is my output on RHEL-7.8, which takes about 6 seconds to run:

 

tux% cd modules/libcom/test/O.linux-x86_64/

tux% ./osiSockTest

Hello everybody,

I have problems with a test in EPICS 7 commit 8fd36d8eef3420b42e7936e949928a6b43df7e15.

osiSockTest seems to take forever. 

'make runtests' hangs here:
osiSockTest.t ................. 1/24

'make tapfiles' hangs here:
perl -CSD osiSockTest.t -tap > osiSockTest.tap

I am testing on RedHat 7 (linux-x86_64).

Any ideas?

Dirk
