![]() When "systemctl daemon-reload" is run at the same time as "systemctl start foo", the latter might hang. That's because commands like start wait for JobRemoved signal to know when the job is finished. But if the job is finished during reloading, the signal is never sent. The hang can be easily reproduced by running # for ((N=1; N>0; N++)) ; do echo $N ; systemctl daemon-reload ; done # for ((N=1; N>0; N++)) ; do echo $N ; systemctl start systemd-coredump.socket ; done in two different terminals. The start command will hang after 1-2 iterations. This keeps track of jobs that were started before reload and finished during it and sends JobRemoved after the reload has finished. |
