The systemd System and Service Manager
6a461d1f59
I had a test machine with ulimit -n set to 1073741816 through pam ("session required pam_limits.so set_all", which copies the limits from PID 1, left over from testing of #10921). test-execute would "hang" and then fail with a timeout when running exec-inaccessiblepaths-proc.service. It turns out that the problem was in close_all_fds(), which would go to the fallback path of doing close() 1073741813 times. Let's just fail if we hit this case. This only matters for cases where both /proc is inaccessible, and the *soft* limit has been raised.
