How do you know this?

The shufangkeji.com mail server have same issue before, It can not give reponse for a while, and it go back automatically. But due to I do not know how long will keep in no reponse state, I ofen restart mail server.

Make a concrete proposal.

I suggest add 4GB swap partition for mail server.

You are the guardian of the email system. If watchdog does not work, you can talk to the watchdog's guardian.

Yes, I have talk to watchdog's guardian. I will keep my responsibility on mail server.
