[jira] Commented: (DIRMINA-302) Unbounded nature of writeRequestQueue can cause OutOfMemoryException

    [ https://issues.apache.org/jira/browse/DIRMINA-302?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12462115 ] 

Trustin Lee commented on DIRMINA-302:
-------------------------------------

It sounds like a good idea to provide a policy configuration per session on the maximum number of pending messages (or bytes).  Let us include it in 2.0.
