Hello,

My Fecthmail scheduler runs in background but does not update next execution date. When I try to change date manually, It gives me error.

This cron task is currently being executed and may not be modified, please try again in a few minutes Traceback (most recent call last):

I tried to change Next Execution date by restarting OpenERP server, but it didn't work.

It works when I restart Postgres service.

Scheduler gets stuck after few days and I have to restart Postgres service. Its interval is 10 minutes. Other schedulers work fine except this and I am not using gunicorn.

I am not able to figure out the problem whether it is OpenERP side or at Postgres side.

Any solution?
