I'm using phpthumb to generate thumbnails from Flickr photos for a site hosted on AWS (free tier). The thumbnails-cache are generated and stored into directories in the following folders:
The problem is that at any given time, the number of thumbnails generated maxes out at 92. A cron job deletes the cache files at regular intervals, and every time only 92 files are deleted. I looked into each individual folder manutally and there always seems to be 92 thumbnails only.
I had hosted the site on another server (non-AWS) and this was not an issue. The cron job used to delete 50k+ files then. So could this be some kind of AWS restriction, or I am missing something else?
