Problem with mysql

[januszmk]

Hi.
Since 2 weeks, I am having problems with mysql. From time to time, I am receiving mysql_connect error on email, and don't know what can cause this:

It's not just cron.php script, but on every one.
Once I had error:

Those are errors you need to show to your host to fix.

Sounds like an overloaded server. When crons are running, it seems your myql server is not able to handle the load. You may want to upgrade your VPS. More RAM & CPU should do.
