Edit Settings page for quiz is not working

Edit Settings page for quiz is not working

Hi,

I'm posting here,rather than in the quiz module forum, because my problem is a bit weired.

I'm using moodle 3.1. i do some patchwork in the code here and there. Everything was well until last day I found that the edit Settings page is not working for quiz. The real problem is that I'm getting a browser's error page-couldnt complete request. So I don't know what to do. 

Quiz edit (adding questions) is working. Edit Settings is working for Other modules. I haven't done any changes to quiz module. The problem seems to be in modest.php or any included files. But how can I debug this situation? Plz help.

I tried in both Chrome and Firefox. My server is Linux. It's available only over intranet. Debug is enabled for my user ID in config.php

We have the same problem with one quiz and also with an image that is being imported in a label. We get this error:


Warning: session_start(): Unable to clear session lock record in /moodle/application-3.0.5.4/lib/classes/session/handler.php on line 42
error/An error occurred whilst communicating with the server
Debug info:

    line 3 of /admin/user.php: call to require_once()


We are using file sessions with memcache. The error logs show a lot of memcache errors:

We have still not resolved it. But it seems similar to this:
