R: java.lang.outOfMemoryError

[Enrico F. <enr...@re...>]

Thank you for your response.
I=92m using 1.3.0 version.=20
I think that the problem is due to the high number of different domain
in a very short time. So, the rate of new domain is greater than the
rate of domain removed from the cache.
I haven=92t seen all the dnsJava code jet, but I think that probably, a
max number of domain to be cached need to be introduced so that the max
amount of memory used by the application can be predetermined. Do you
think I=92m right?

In the next day, in my spare time, I=92ll try to better investigate the
problem. =20

What version of dnsjava?  1.3.0 uses a lot less memory than 1.2.4, and
is=20
better about removing expired data.

If you're using 1.2.4, upgrade.  If you're using 1.3.0, I'm not really=20
sure.
