Bernd Fondermann commented on JAMES-512: ---------------------------------------- a db configuration runs into memory problems (Xmx=64m) after less than two hours, too. (this is a setup where 500 mails are created per minute, which is quite a load: 30 000 mails/hr!) > 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 > Assignee: Noel J. Bergman > Priority: Critical > Fix For: 2.3.0a4 > Attachments: james-512.patch, 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, } > 110 > 111, return stream; -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
