Hi,
|
|
|
|
We have just tried to update your installation but it looks like the InnoDB buffer size is too low.
|
|
|
|
Because of this we have stopped the auto-update running to ensure your system is ok.
|
|
|
|
You currently have a configured innodb_buffer_pool_size of ' . $pool_size / 1024 / 1024 . ' MiB but is currently using ' . $pool_used / 1024 / 1024 . ' MiB
|
|
|
|
Take a look at https://dev.mysql.com/doc/refman/5.6/en/innodb-buffer-pool.html for further details.

|
|
|
The ' . $config['project_name'] . ' team.';
