Hello again,

I found this was already a topic in this list:


Sorry, for that.

I think the explanation for my problem is that the mysql 8 hours default 
timeout exceeds. As I have only one zone configured at the moment there 
are no queries in the meantime.
I set the wait_timeout value to 86400. I guess this will solve the problem.
