inotifywait times out immediately

Describe the bug

I’ve been using inotifywait to watch directories on SLES15 SP3. When I launch inotifywait (even with the -r flag), it says “Watches established” and then exits with exit code 2 without reporting an event.

To Reproduce
Steps to reproduce the behavior:

From command line, run inotifywait -r -e close_write /home/suhas/testdir
Observe that after setting up watches, the process immediately exits:
Setting up watches. Beware: since -r was given, this may take a while! Watches established.
Check the exit code with echo $?
Observe response of 2.
Expected behavior
Inotifywait should wait indefinitely for an event.

Desktop (please complete the following information):

Version: 3.14 (via suse repository)
Additional context
This behavior was not happening until today. I just tried restarting the service but that didn’t make a difference.
