On a release of cacti 1.2.29 (not the latest) I have a bunch of error with boost.
I still see the poller_output_boost_arch (152 of them).

and in the log I got those errors:
13/03/2025 08:16:05 - CMDPHP PHP ERROR Backtrace: (CactiShutdownHandler()) 13/03/2025 08:16:05 - ERROR PHP ERROR: Uncaught TypeError: numfmt_format(): Argument #2 ($num) must be of type int|float, string given in /usr/share/cacti/include/global_languages.php:881 Stack trace: #0 /usr/share/cacti/include/global_languages.php(881): numfmt_format() #1 /usr/share/cacti/utilities.php(2835): number_format_i18n() #2 /usr/share/cacti/utilities.php(84): boost_display_run_status() #3 {main} thrown in file: /usr/share/cacti/include/global_languages.php on line: 881

And this one too:
13/03/2025 00:56:36 - CMDPHP PHP ERROR WARNING Backtrace: (/poller_boost.php[216]:boost_log_statistics(), /poller_boost.php[1274]:CactiErrorHandler()) 13/03/2025 00:56:36 - ERROR PHP WARNING: Undefined array key "rrdupdate" in file: /usr/share/cacti/poller_boost.php on line: 1274

Any clue ?
