More than once a day is suspicious.

I would try to track down why it's changing servers so often. One
possible explanation is that network problems (or intermittent connectivity)
is causing it to lose sync, then it when it re-acquires sync it has no
special reason to prefer the server it was synched to awhile ago.
Only if you know the problem is due to something that doesn't need to be
fixed would I look to using 'prefer' to make the issue go away. Generally
all the servers available should be equally good, and the server should
stick to one of them.
