3.4 Use of signals
A running dirmngr may be controlled by signals, i.e. using
the kill command to send a signal to the process.
Here is a list of supported signals:
- This signal flushes all internally cached CRLs as well as any cached
certificates. Then the certificate cache is reinitialized as on
startup. Options are re-read from the configuration file. Instead of
sending this signal it is better to use
gpgconf --reload dirmngr
- Shuts down the process but waits until all current requests are
fulfilled. If the process has received 3 of these signals and requests
are still pending, a shutdown is forced. You may also use
gpgconf --kill dirmngr
instead of this signal
- Shuts down the process immediately.
- This prints some caching statistics to the log file.
