nit: use the OCP\Log\logger function because it includes error handling when the loggerinterface can't be resolved

learning from my own pr #45804 is to not encode the threshold in the log message as it makes grepping harder 😬
How about we log Excessive memory used or similar and put the threshold into the context object of the log?

But then we don't see it right away in lnav or any other tool. Since it's at the end you can already grep for Used memory was more than 400 MB: ?
