MDL-51111-muc-reset -
Now and then the file-based MUC settings seems to be reset.
We have added an external memcached store and sometimes the config.php is reset to default settings. That means we have to reconfigure the memcached instance everytime and edit the store mappings when this happens.
This MUC config file resides in our NFS shared moodledata: /moodledata/moodle/muc/config.php
I have not yet figured out how to trigger this behaviour and currently it occurs randomly like once a week or once per two or three weeks. We have also had times when it occured more often.
There are also others experiencing this:
