I occasionally get reports from people saying that they find the wiki locked. The usual effect is that you edit a page and try to save, it waits for a while and finally you get a message saying that the “main lock exists” and a time period.
If the time window is large, twenty minutes or more, for example, chances are that the lock was left behind after a crash. You can click on Administration → Unlock Wiki and that should solve the problem.
I’d still like to know what keeps crashing the site. A few days ago I changed the way the maintenance job cleans up our git directory (Git repository). The log files indicated that this was where it crashed. I was able to reproduce it and changed how git is called from Perl. I recently started posting the result of the maintenance job, just in case there’s a similar problem in the future.
Sometimes it takes a really long time to save an edit. I suspect this happens when github is slow. I push all changes immediately. Maybe I should change that. Git is still on my mind.
Thanks for your efforts looking into this, Alex. – DrewAdams
