I'm running w3tc version 0.9.2.11 on a WordPress install, and my host NearlyFreeSpeech. Most things are running fine, but I've noticed that my wp-content/cache/tmp folder is filling up with files that don't seem to be getting removed.
Right now the only features that are active are the page cache, the DB cache, the browser cache, and I've got a CDN.
I read a couple of other forum threads that noted similar behavior in version 0.9.2.7, but I've confirmed that I'm up to date and that the issue is still present.
My host is a bit unusual in the level of security they have on every site's files and directories. Thus, there might be something somewhat unique about my situation that will require some additional debug.
How do I go about debugging this issue? Where are these files written? Is there a log file or something similar I should be checking for errors?
