[jira] [Updated] (DIRMINA-1070) Avoid unbounded message queueing when sending large amounts of data to slow clients

     [ https://issues.apache.org/jira/browse/DIRMINA-1070?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

jpalacios updated DIRMINA-1070:
-------------------------------
    Description: Our application runs an Apache MINA server to provide SSH support. We are seeing {{OutOfMemoryError}} s when certain clients establish a session with a large {{Window}} size. Particularly clients like TortoiseGit (which uses TortoisePlink which in turn seems to use Putty) use an initial window size of 2GB. From heap dumps we can see that the {{DefaultWriteRequestQueue}} is filling up with {{WriteRequest}} instances and taking up gigabytes of space until the heap blows.
