Intermittent AJAX errors

  1. I am getting the same AJAX errors being reported by others, either when adding a field or saving the form. I just spent several hours to see which version of wordpress or which plugin is causing the problem but I kept running in circles. I went back to my original installation of everything and I now see that if I click an action multiple times, it works once after perhaps several failures. So I guess I have a poor workaround for now.

    Any suggest on how to track down the problem?

    I have already: increased memory to 128M, uninstalled everything and re-installed, and activated plugins one at a time. The minimal config to get an error seems to be wordpress 3.4.2 and nextgen-gallery which was the first plugin I activated. Once I see an error, the problem seems to be "sticky". I can deactivate, and delete the other plugins, and reboot the server, and the problem continues. While the errors are happening, I can install a second website instance on the same server and it works ok. I have debug logs etc, and I don't see an error message logged. When it happens, the access log does not record a post to admin-ajax.php.

  2. Correction, the POST is being logged w/200 response sometime after AJAX gives up after 19 seconds. When it works, the POST returns quickly. I'll keep looking for the cause. Is anyone else working on this? I'd like to exchange notes. Thanks.
