Determine Message Size in Mailet
I am having a problem with a mailet when copying the Mail mail object to a
MimeMessage.
MimeMessage message = mail.getMessage();
It only occurs when the message contains large attachments. Usually larger
than 2 MB. I receive the following error in the Mailet.log
java.lang.OutOfMemoryError
And the message is sent to the Error Processor.
Is there a way to test the size of the mail object before copying it to a
MimeMessage to access the getSize() method?
I experience the problem in both James 2.1.3 and James 2.2.0a15. Runing on
RedHat 9 or on Windows XP and 2000. The systems have 512 MB and 1.8GHz
processors, so I don't think it is resource related. I am using Sun Java
version j2re1.4.2_03
Thanks

Oh, and let me add that documentation (or perhaps I should say hints)
about that memory-increasing command line option can be found in
places like this
<http://java.sun.com/j2se/1.4.1/docs/tooldocs/windows/java.html>.

I think one way to deal with this is to give the JVM more memory to
work with than it gets by default. You can do this with a command
line option to the "java" command, an option like "-Xmx96m".
I had this working once, after experimenting some, and was thereby
able to process bigger messages through JavaMail. Unfortunately, now
I can't find specifically what option I used. You may succeed with
trial and error.
As I recall, the JVM gets 64 megs by default in my situation.

Thanks Corey,
That worked. I set the following options -Xms64m and -Xmx128m

Are you running any special start-up parameters with the JVM?
I have Phoenix (James) running with these parameters:
JVM_OPTS="-server -ms384m -mx384m -Djava.ext.dirs=$PHOENIX_HOME/lib"
The above is used in the phoenix.sh startup script. The server i am
running James on has 2GB RAM.. so you may want to lower the 384 to maybe
256m or 128m... since your server is running with 512MB RAM.
Not sure if it is related.. but you could try this and see if you still
get the OutOfMemoryError.

Re: Determine Message Size in Mailet

The service code is as follows: I have only inclued the part where the
problem occurs. From what I can tell in all logging, is that it enters the
mailet, it logs the message: 'Copying to MimeMessage', then I get the
java.lang.OutOfMemoryError and it never logs the 'Message getSize' line. As
I said previously, it only does this on messages with large attachments.
public void service(Mail mail) throws MessagingException {
try {
log("Copying to MimeMessage");
MimeMessage message = mail.getMessage();
log("Message getSize()" + message.getSize());
. . .
catch (Exception e) {
log("Exception: "
+ e.getMessage(), e);
throw new MessagingException("Exception thrown", e);
}
}

Weird problem. I am doing the same thing in a mailet.. without any
issues. But i am running on Solaris 8 for SPARC.
can you email to list the service method code for your mailet?

Increase the available heap size for James using JVM_OPTS. The default is
too small for your needs.
