Unresponsive child for request

[Mark Jones]

I am getting this error in my logs and I understand it is do to likley an 
issue with sql but was wondering what the criteria for this error to be 
generrated is.

Error: WARNING: Unresponsive child for request 271737, in module sqlzuul 
component accounting

Basically I assume and sql query is sent and if there is no response in x 
seconds this error is generated.

Or am I completly wrong here?
