Installations that are based on the DEB distribution (Debian, Ubuntu and derivatives) can be configured with a workaround as follows (note that upgrading to Openfire 4.6.5 remains the preferred solution).

These installs typically have a configuration file in /etc/default/openfire that can be used to apply additional configuration to Openfire. The default file looks something like this:

# Defaults for openfire initscript
# sourced by /etc/init.d/openfire
# installed at /etc/default/openfire by the maintainer scripts

#
# This is a POSIX shell fragment
#

# If you wish to override the auto-detected JAVA_HOME variable, uncomment
# and change the following line.
#JAVA_HOME=/usr/java/default

# Additional options that are passed to the Daemon.
DAEMON_OPTS=""

Modify the value of the DAEMON_OPTS property to include the -Dlog4j2.formatMsgNoLookups=true directive. Make sure that the line does not start with a # character. If your instance was already using the DAEMON_OPTS line, then add the new option to the existing values, separating them with a whitespace character (ensure to include everything within the quote " characters).

The new file content could look something like this:

# Defaults for openfire initscript
# sourced by /etc/init.d/openfire
# installed at /etc/default/openfire by the maintainer scripts

#
# This is a POSIX shell fragment
#

# If you wish to override the auto-detected JAVA_HOME variable, uncomment
# and change the following line.
#JAVA_HOME=/usr/java/default

# Additional options that are passed to the Daemon.
DAEMON_OPTS="-Dlog4j2.formatMsgNoLookups=true"

After saving the file, restart Openfire (note this will briefly interrupt service).

# systemctl restart openfire

To check if your changes were successful issue the following command:

# ps ax | grep openfire

The output should include the formatMsgNoLookups option, like in the example below:

   3173 ?        Sl     0:02 /bin/java -Dlog4j2.formatMsgNoLookups=true -server -DopenfireHome=/usr/share/openfire -Dlog4j.configurationFile=/usr/share/openfire/lib/log4j2.xml -Dopenfire.lib.dir=/usr/share/openfire/lib -classpath /usr/share/openfire/lib/startup.jar -jar /usr/share/openfire/lib/startup.jar
