PHP Fatal error: Uncaught Exception: Error: Too many active concurrent transactions

[isscbta]

The error message you're seeing indicates that MySQL is currently handling the maximum number of concurrent transactions that it can support. This can happen when too many database operations (like INSERT, UPDATE, DELETE, etc.) are taking place at the same time.

But this could also be just a temporary bug that can be resolved by restarting the database.

In your SSH, as root, run:

Code: Select all

systemctl restart mysql
