[ http://issues.apache.org/jira/browse/JAMES-134?page=comments#action_12434107 ] Marco Trevisan commented on JAMES-134: --------------------------------------
Hello all, My 2 cents about the problem: First. JVM >= 1.5.0 have dynamic heap resizing: the problem about "memory releasing" can be solved by simply switching to JDK 1.5.0 or higher. It is still important to ensure the correct objects finalization in order for gc to do its work. Second. About OG's early comment "A) A mail server shouldn't take so much RAM. It doesn't have to take RAM of the size of the messages that it delivers.": let's look at the situation at a little higher level. In order to process a mail message a mail server (which should be capable of processing it in complex ways) may need to have the whole message in RAM, i.e. when processing algorythms are not sequential and performance is welcome. In my opinion the message body should be kept in a file (as Rich said) only if there is no need to process it here.
