MX Entry is missing once a day

I have a problem with DNS and MX Entry;

DNS zone for had no problems for months in a new VPS; CENTOS 6.5 x64 and WHM 11.40.1 (build 9)

MX record is; 14400 IN MX 0
And when I look at Edit MX Entry, I saw that MX entry is there.

But once or twice a day MX Entry for is missing from the list, so e-mails cannot be received or send from the server for e-mail accounts. It's really once a day, no server restart, no change in configuration, no change in DNS; I even don't login to WHM or Cpanel. I check my mails so often, then I see that [email protected] mail account is not working, I check WHM and see that MX entry dissappeared.

Delete and create MX record doesn't solve the problem, it doesn't automatically create MX Entry for I delete DNS record of, add again, then MX entry appears in the list and mails are working without any problem.

How can this happen, how can I examine this situation and what will be the cause and the solution?
