Big thank you to Ralph for tracking that down and for teaching me about strace. Also thanks to those who reproduced the problem, which was not after all as general my message subject had advertised. I recall noticing years ago that Screen tends to start somewhat slowly as a result of closing 4000 file descriptors. I never bothered to figure out why it did this. I guess it's good that Systemd exercised this a bit, since now we can fix a decades-old bug. Frederick On Fri, Mar 08, 2019 at 11:49:29AM +0000, Ralph Corderoy wrote:
