I'm experiencing the problem too:
http://forums.modx.com/thread/79847/revo-2-2-5-adv-file-media-source-errors#dis-post-441212
No static elements, but I have 7 image TVs all under the same category. Each has Input Type set to Image and Output set to Default. Only Media Source is the default web context with Filesystem source.
All that said, I think I may have been getting the error before creating any of the image TVs, but I'm not 100% on that.
Looking at the log, it appears that the error started around the time I added some components. For about 10 days after a fresh install of 2.2.5-pl trad. there were no errors and during that time I installed Wayfinder and getResources. A few days later I then installed QuickCrumbs, TinyMCE and FormIt. The errors started around the time I installed QuickCrumbs, but it doesn't appear to be the cause as I have uninstalled it and the errors continue at a voluminous rate.
Don't know where else to look. Open to suggestions...
