Subject [jira] [Commented] (VYSPER-332) Memory Leak in BoshBackedSessionContext
Date Tue, 13 Nov 2012 06:29:12 GMT

    [ https://issues.apache.org/jira/browse/VYSPER-332?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13495990#comment-13495990

Bernd Fondermann commented on VYSPER-332:
-----------------------------------------

How do you interpret this?
My take is that it seems like a rouge client swamps the server with Presence messages in extremely
short intervals. 
Vysper only has so much bandwith to deal with it. You'd need to enlarge internal buffers to
be able to cope with that.

my web application.  Specifically, I am seeing the  consume 300+ megabytes of heap causing
an OOME.  The heap dump indicates that roughly 85% of my memory is consumed but the single
