1. can you share a bit more details on how you are using activemq (or intending to use activemq) with james? is your app downloading a bunch of data and storing/caching-all-those-emails in memory? are you aware that MDBs may be pooled via activemq and your MDBs may never reinitialize memory, and you are just continuously storing new emails or same emails in memory without dumping memory at entry or exit points of your consumer?
for example, in my app, i use @Schedule + javamail to check gmail account INBOX folder, if any messages, I use activemq (and MDB) to insert the data from email to database, send a success/failure email to office personnel, and email(s) in inbox are moved to trash folder. inbox never has many emails, because after emails are 'processed', then they are moved to trash folder, so my app/server is never using much memory to download a bunch of emails, etc... 2. if you removed activemq, would you app still experience out of memory error? 3. any reason why you are using james 'beta'? maybe an older (more stable) release is available and performs better? 4. is it required that you use older version of activemq instead of newer, latest version, or more/most stable version of activemq? i'm using activemq 5.8 (which is bundled with tomee), and i have no (memory) issues, and I also use activemq to update google calendar via google calendar API after enduser make certain changes in database via web app. On Wed, Oct 30, 2013 at 11:54 AM, sheshasai <sheshasai.mog...@gmail.com>wrote: > Configuration is > Activemq 5.4.2 with james beta 3 > Jdk 1.6.0 > Spring container > and getting the error could not out of memory ,create the native threads , > what we can suspect from activemq side like any configuration issues > > > > -- > View this message in context: > http://activemq.2283324.n4.nabble.com/I-am-getting-the-out-the-memory-error-while-using-the-james-mail-with-activemq-tp4673422p4673501.html > Sent from the ActiveMQ - User mailing list archive at Nabble.com. >
