> OutOfMemoryError -- object not released.
> ----------------------------------------
>
> Key: JAMES-512
> URL: http://issues.apache.org/jira/browse/JAMES-512
> Project: James
> Type: Bug
> Components: MailStore & MailRepository
> Versions: 2.2.0
> Environment: windows XP,
> Java 1.5.0_06
> Reporter: Quande Ren
> Priority: Critical
> Fix For: 2.3.0a4
> Attachments: picture.GIF
>
> I use the file system to store the emails.
> When I run the James for a long time, the james server used more and more
> heap memory, eventually it runs out of memory and refuse to receive email.
> only restart the james will work.
> I used JProfile Memory Debugger(you can get the trial version from
> www.quest.com) and found a clue. the object allocated from following code at
> line 92 does not always get released, cause the memory been used up
> eventually. I will attach a picture file showing the call stack.
> 91, final OutputStream outputStream = getOutputStream( key );
> 92, final BufferedOutputStream stream = new BufferedOutputStream(
> outputStream );
> 93
> 94, final Object o = m_outputs.get( key );
> 95, if( null == o )
> 96, {
> 97, m_outputs.put( key; stream );
> 98, }
> 99, else if( o instanceof ArrayList )
> 100, {
> 101, ( (ArrayList)o ).add( stream );
> 102, }
> 103, else
> 104, {
> 105, final ArrayList list = new ArrayList();
> 106, list.add( o );
> 107, list.add( stream );
> 108, m_outputs.put( key; list );
> 109, }
