6.5GB in mmr directory

wowzers, thats crazy. It certainly should be. What happens to that directory when you purge all files?

When we purge manually, it does clear the files, but I was expecting it to purge itself and only keep recent files (which it isn’t).

How quickly does it get to 6.5GB?

MMR creates a hash of the filenames that it merges. It deletes old files based on this. If you are adding new CSS/JS files or renaming the old ones the hash will change. Its possible these files aren’t being cleared due to this.

It took about a week to get to that size.

And not adding any new files or content.

I’d say there is a plugin conflict here.. maybe the hash is changing on every reload causing new files to be created every time. Are you able to check if you get the same hash after a normal reload?

Could well be a plugin conflict but I’ve no idea which one and why tho.

It’s most likely something to do with the plugins WP Super Cache, and Minify HTML, so I’ll disable those and see how it runs without them for a while.

Is there a way here I can send you some screenshots privately and/or login details … the log files are a bit weird, it looks like it’s compressing the css once, and then doing it once more, and then again, and then again and not clearing any of the old files. Same with javascript.

Yep, if you can email me the login I’ll take a look. Click on our username and then click on the email link on our website or use the contact form.

Thank you, I’ve sent you an email thru the website ??

This is now resolved. The error was with the gantry 4 theme plugin. It was adding a random int to the css handle on every page load.

Thank you for looking into this for us, very helpful and responsive, much appreciated.

The same happen to me, but during several months it creates 50+ GB mmr/ directory. Now I am trying to manually delete it.

I am also using Minify HTML plugin together.

Currently a lot of files is created there and I am unable to list anything in that directory. I try to keep an eye on this folder to find some rules why new files are always created.

OK thanks for help from other comments – it was also by generated css internal WP name in theme/plugin. May be some detection than more than several thousand files exists -> and display some warning on every admin page will help.

Thats a good idea, I’ll see if I can add it in the next update.
