The port security/i2pd installs a configuration file for newsyslog to rotate /var/log/i2pd/i2pd.log and compress old copy and then send signal 1 to i2pd.
i2pd ignores the signal and does not close/reopen the log so newly created by the newsysod i2pd.log remains unused and i2pd continues writing to now unlinked old file filling /var indefinitely.
