I have a user who when he closes the tab on an interactive desktop and deletes the session gets a long list of errors starting with:

#\<ActionView::Template::Error: No such file or directory - /var/www/ood/apps/sys/7cfd9a6d-afcc-4145-bcc4-e373d42d2a95\>

As you can see that it is looking for the users session directory not in his home directory but in the /var/www/ood/apps/sys application directory. This doesn’t always happen to them and they seem to be the only one it happens to. There is nothing unusual in the /var/log/ondemand\_nginx/user/error.log file and only some missing font errors in the vnc.log file for the session. Is there something else I should look at to see why this is happening?

It’s a transitory error - meaning it just happens sometimes. Could happen to anyone. It can be safely ignored and the user should just try to delete the session again.
