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:

'SIGHUP'
     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

'SIGTERM'
     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

'SIGINT'
     Shuts down the process immediately.

'SIGUSR1'
     This prints some caching statistics to the log file.
