Error: MySQL server has gone away - It isn't cacti issue. check mysql server log SHOW GLOBAL VARIABLES LIKE 'max_connections'; SHOW GLOBAL STATUS LIKE 'max_used%';

Its a mactrack problem, mysql isnt really going away.

MariaDB [(none)]> SHOW GLOBAL VARIABLES LIKE 'max_connections';
SHOW GLOBAL STATUS LIKE 'max_used%';
+-----------------+-------+
| Variable_name   | Value |
+-----------------+-------+
| max_connections | 1000  |
+-----------------+-------+
1 row in set (0.001 sec)

Try to change in lib/mactrack_functions.php ling 753: if ($ifOperStatus[$ifIndex] == 1) { to if (isset($ifOperStatus[$ifIndex]) && $ifOperStatus[$ifIndex] == 1) {

Do you have php 8.x?

I think we need a wrapper function to accommodate the unset variables since @ does not work like it used to. That's a fairly big project.
