Subject: Re: Tomcat Not Releasing URL Connection
The IBM JVM 1.5 and Tomcat 5.0.x are all that is available on the
(official) Suse SLES 10 CD/DVD.
I'm not suggesting that the OP replace the IBM JRE as the default one, just to
use the Sun JRE in an attempt to narrow down the scope of the problem. If
using the Sun JRE cures the problem, then the OP can take up the issue with
IBM; if it doesn't, then at least one variable is eliminated and the other
possibilities can be looked at.
Doing a little Googling, I found a couple of system properties that affect the
DNS cache in a JVM instance:
sun.net.inetaddr.ttl
networkaddress.cache.ttl
Setting either or both of these to 0 via command line parameters might help.
(Setting them programmatically seems to have problems; see:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6247501
for more info.)
... and some more complete info for Sun JVM 6 is available at
http://java.sun.com/javase/6/docs/technotes/guides/net/properties.html

Rainer
