Okay, some more questions:

- do you specify a sufficiently large value for max-cache-size? (maybe
  if you can post your named.conf that would be helpful)
- does the trouble keep happening, or is that something like a
  spike-type trouble (which then subsides)?
- if you perform 'rndc recursion' during the errors are happening, do
  you see anything strange in the corresponding named.recursing file?
  For example, are there clients that are too old, i.e., should be
  timed out but not?
