[Bela Ban (JIRA)]

    [ https://jira.jboss.org/browse/JGRP-1256?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12566482#comment-12566482 ] 

Bela Ban commented on JGRP-1256:
--------------------------------

Yes, I agree: iterating from low to highest_received and removing all messages from xmit_table until xmit_table.size() <= max_xmit_buf_size is correct.

However, I'm seriously thinking about removing max_xmit_buf_size altogether (see above)...

long current=low;
                while(max_xmit_buf_size > 0 && xmit_table.size() > max_xmit_buf_size && current <= highest_received) {
                    xmit_table.remove(current);
                    retransmitter.remove(current);
                    if(current > highest_delivered)
                        highest_delivered=next_to_remove;
                    current++;
                }

> it is possible for the NakReceiverWindow to enter an infinite loop if max_xmit_buf_size has been set.
