Hi , We have very similiar problem. Try to set-up mysql timeout per connection like this :
wait_timeout=100 ( or other suitble time for you ) interactive_timeout=100 ( or other suitble time for you ) in my.cnfIf a connection is idle more than 100 seconds mysql will kill a connection. Next time apache will connect again do the job .. after 100 seconds idle ... realize a connection.
