Hi,

The problem i mentioned is not about the OpenERP server for Q/A. It is about our own OpenERP production server. But as Sven Boudesseul said, even OpenERP SA is experiencing the same problem.

I have guessed a few reasons for this 502 problem. They are:

1) The OpenERP server stops working, when it encounters a critical issue during the runtime.

2) The OpenERP server stops working, when python workload is very high to extend of not being able to process it further.

The solution that I have found is :

1) To write a cron job in linux / a scheduler in windows that keeps checking whether the python/openerp process is running or not. It can be once in 30 sec or a min. once it finds that the openerp server is not running or python process is not running, the responsive action of the cron job/scheduler is to start the process.

I have been using this solution for many months without any problem. My client is also happy that OpenERP server is up all the time except the few minutes when it stops working.

Thanks
