问题 I have a server hosting a website of mine that has almost zero-traffic. A few people (< 20) enter the site every day, and a few RSS readers are subscribed to some feeds we put out. Almost every night, an RSS reader will hit us in the middle of the night and get an exception that the website can't connect to the SQL Server because of a Timeout in the connection. The details are extremely weird, so I'm looking for some help on what could be the issue, since I don't know where to start looking

The only workaround is to turn off safe mode or by changing the time limit in the php.ini. -- PHP manual, Runtime Configuration, description of max_execution_time Many

But I want the server to shutdown immediately - even if this means breaking up with currently handled requests. What I can not do
