Give a try to, module numa_exceptions

It will store in database any exception including stack frame AND local variable values at exception time. You will find a new menu entry Exceptions in settings menu, in technicall view

It helps a lot with non easy to reproduce faults, and most of the times you don't even should ask your customer to reproduce the steps to get the exception because all the needed info is in the recorded log

Be careful: it uses monkey patching to be installed, so once is copied into the addons path will intercept exceptions. Install it as soon you copy the module and if you want to remove it, remove the module from the addons path

I will appreciate any comments

Hello everyone,

On the production instance of a customer, I'm facing a hard to reproduce
bug, and I don't understand what is happening.

Context: Odoo v8, and there is an external application which uses the
Odoo XMLRPC API to create / write things in the Odoo database.

Most of the time, everything goes very well. But sometimes, an XMLRPC
call will raise OperationalError: Unable to use a closed cursor.

A sample stack trace for this is attached. Rerunning the same XMLRPC
call succeeds.

I'm unable to imagine a scenario explaining this, and your feedback is
