/Library/Developer/CommandLineTools/usr/bin/make stopped working with latest OSX update

                            2596 read  (in libsystem_kernel.dylib) + 10  [0x7ff813f8afee]

This suggests it’s hung trying to read from a file descriptor. Does this reproduce with a trivial makefile? For example:

% ls -l
total 8
-rw-r--r--@ 1 quinn  staff  27 29 Aug 09:39 Makefile
% cat Makefile 
test.txt:
	date > test.txt
% make 
date > test.txt
% ls -l
total 16
-rw-r--r--@ 1 quinn  staff  27 29 Aug 09:39 Makefile
-rw-r--r--  1 quinn  staff  29 29 Aug 09:40 test.txt

The example above appears to work fine. It could be related to the specific file descriptor as you mentioned above.

Additional information:

• It works correctly for some period of time after reboot.
• Once it gets in to this situation, the only way to clear it is to reboot.
• Appears to also occur with Homebrew gmake.
• I'm also see an issue where a service I have created to write output to a file on a regular interval also timeout.

Here is the service definition and the script to reproduce:

OK, so make is working fine, but this specific make job is causing the failure.

As a next step I recommend that you try to track down what sort of file descriptor is causing the problem. If you run lsof against make when it’s hung this way, that might offer a clue.

Another note: It looks like both the script failure above and the make failures occur at the same time although not sure how they would be connected.

That shows that make has 5 file descriptors open:

• 0 through 2 are stdin, stdout, and stderr.

• 3 is the Makefile itself.

• 4 is a pipe.

Of these, the obvious candidate for causing problems is 4. Note the ->0x113baff81831caff marker. If you do a full lsof and search for 0x113baff81831caff, that should show you the other end of the pipe.

Interesting. Looks like there is a shell entry in the Makefile and Docker Desktop is hung. Restarting docker engine frees the pipe. Mystery solved.
