This site has been running fine for over a year. Upgraded to 2.4.0 the day it was released and no problems reported at the time, but this problem is in an area that wasn't used all that often.
This last few days, in the CMS, client has been noticing that the iFrame boxes that usually hold the images and files for thier pages have be sporadically displaying "too many connections" errors. Sometimes, and I have seen this myself, they simply dislplay a blank grey box. No image, no "Attach Files" dialog.
The custom page type is fairly complex i guess. 6 Additional tabs. One has 3 FileIFrameField's, another tab has 10 ImageField's. In addition, the site's traffic has doubled since launch, but still very low by most standards.
Has anyone every had a problem like this, or noticed areas where Silverstripe was not closing connections?
