Hello, I have a similar problem using joomsef 3.9.8, occasionally the website go down with this error message: "JoomSEF Error - Could not save the SEF URL to database" and launching the crawler doesn't work. Leaving pass a few of time and restarting the crawler then the process start correctly.

thanks
