winbind crashes every sunday

[warriorelric]

Hi

I have a problem with a ubuntu 8.04 box and wondering if anyone can help.

Basically the box is configured with ubuntu server and has shorewall, webmin and winbind running on it. This also doubles up as router between different subnets in our environment and every sunday completly falls over. After disabling any weekly cron jobs this is still happening and the only thing I can find in the logs is with reference to samba and winbind:
