I have just been dealing with a problem whereby http requests are being aborted, seemingly at random.

On any particular page in the website, when you opened a page, a number of the assets (img, css, etc) failed to load. If you refreshed, the page may work fine, the same set of assets may fail to load or different assets may fail to load.

The net tab in firefox was returning 'Aborted' in the HTTP status code column for the failed assets, even tho in the case of images, the image previews were still working.

There was nothing in any of the apache logs about the requests that failed, however since it seemed to point to an apache issue, we restarted apache. The first time we tried, it made no difference but about 10 minutes later, in the absence of a better solution we tried again. Bizarrely, the problem disappeared immeadiately.

So now the site seems to be running fine again but its rather unsettling, both the intermittent nature of the problem and the lack of an explanation for its resolution.

Has anyone seen anything like this before and if so did you find out the reason behind it?

Many Thanks
