No, because the amount of memory per cached domain is not constant, so=20
limiting the cache based on the number of domains won't work as you'd=20
expect.

The ultimate correct solution is to make the cache cleaner more=20
aggressive, and more likely to successfully clean the entire cache withou=
t=20
getting an exception.  This means that the cache would need a new data=20
structure.

A good temporary solution would be to add a setMaxCache() function to the=
=20
Cache object, like the setMaxNCache() function.  Then you could set all=20
data to be cached for no more than, say, an hour, and the cache cleaner=20
would hopefully be able to remove more of it.

In any case, I won't have time to touch dnsjava code at all for the next=20
few weeks.

OK.
