The default session timeout is 30 minutes, so you could potentially have 1/2 MiB of data /per session/ laying around for 30 minutes or so. This could certainly bust your heap. | Would it be worth reducing the session timeout?

Is there any reason for a session at all? Maybe if you explain a little more about what the service does, we could help you optimize it a bit. Do you handle all the processing during the request, or do you store the document for batch processing and immediately return a response to the client? If you do everything during the request, I suspect that sessions are not necessary at all. Eliminating sessions entirely can improve the performance of your application and significantly improve your memory footprint. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkg+xOEACgkQ9CaO5/Lv0PCjtwCfa/4RamyXFlGyjWg3yQsULNwJ oHQAn3hkQPy+YGx6kTJt909Ay6ohzlve =iraR -----END PGP SIGNATURE----- --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
