Sheduler stop working; can't turn off
have problem with Scheduled Action in OpenERP.
Once a few days my schedulers responsible for getting and sending emails (Email Queue Manager, Fetchmail Service) stop working, 'Next Execution Date' is set to past date and I can't inactivate it (Message: This cron task is currently being executed and may not be modified, please try again in a few minutes).
I found solution (login to PostgreSQL console and manually change active to false) but it is inconvenient and I have to keep an eye on it all time.
How to find reason why the services stop working?
I don't see nothing suspicious in openerp logs.
I am not sure if it is reason but problem probably appeared when client moved emails to office365.
