Resource: Process Time
Exceeded: 2094 > 1800 (seconds)
Executable: /usr/bin/php
Command Line: /usr/bin/php /home/XXXX/public_html/index.

The tech said:
I apologize for the delay. It seems that MySQL was causing very high I/O wait times on the server bringing it to a crawl. Restarting the MySQL server has fix this. Please let me know if you have any further questions or concerns.

is there a way how to fix this?

Are you an a shared server or on a VPS or dedicated server?
Is you Mysql configuration file optimized for Innodb?

Xenforo uses mainly Innodb tables and if your VPS is a standard install without any optimization you will experience heavy performance problems.

Take a look at your /etc/my.cnf file and look for an entry "innodb_buffer_pool_size=2G". If there is no such entry or if it has a very low value correct it to
innodb_flush_method = O_DIRECT
innodb_buffer_pool_size = 2G
