I've noticed that when I approve SOs or POs sometimes odoo hangs.  I get the cute messages about it still doing work and get a cup of coffee etc.  But it doesn't ever finish, at least for the 30 minutes that I've managed to wait for.

We end up stopping and starting g the odoo server from terminal.  Does anyone else get this behavior?  How can I debug this and find out what is causing the hang up?

Thanks
