I'm having the same problem, same thing in my logs. A customer makes a change to their hosting account, Plesk initiates a graceful restart of apache and it doesn't come back.. I have to scramble onto SSH and type "service httpd restart" and everything is immediately fixed.

Tested setting my restart interval to 0, didn't help. It actually crashed more, which makes sense.

It's sort of an intermittent problem because you have to let apache work a bit before it'll have some connections to hang on.
