Plesk controlpanel does not change Bind DNS files

[rooyevaar]

I use Plesk 7.5.3 for about a year now, without any problems.
This week, without any changes, updates or anything like that, I cannot add DNS entries in Plesk anymore.
When I do, the web interface seems to hang. When after a while I restart the Plesk Control Panel , the DNS change most of the time shows in the Plesk screen.
The BIND files haven't changed though.

Does anybody have a solution for this?
I allready tried adding a dummy record to force a rewrite of the file, but the same thing occurs.

Please help.
