Stefano Bagnara resolved JAMES-592.
-----------------------------------
Resolution: Fixed
Fix Version/s: (was: Next Minor)
(was: Next Major)
Assignee: Stefano Bagnara (was: Noel J. Bergman)
Now james uses a default 300 seconds expiration for the positive dns results
cache.
The expiration is tunable via system property -Dnetworkaddress.cache.ttl
Setting it to -1 will revert to the default "cache forever" JVM behaviour.
Setting it to 0 will remove caching at all.
Applied to trunk 4 days ago and backported to v2.3 (for 2.3.1) now.
> OOM caused by unbounded cache in InetAddress (was James leaks memory slowly)
