I want to know How to debug Odoo v11 server hangs when I click on an account from Chart of Accounts.  I can navigate everywhere in Odoo just fine, but when I click on Accounting > Chart of Accounts and pick an account, it spins endlessly.

Well sometimes (i just noticed) it does load, but it takes well over 5 minutes to do so.

How can I find out what is going on behind the scenes on my ubuntu server that is causing this issue?
