Transport: warning if receiver and/or send buffer sizes cannot be allocated
---------------------------------------------------------------------------

                 Key: JGRP-870
                 URL: https://jira.jboss.org/jira/browse/JGRP-870
             Project: JGroups
          Issue Type: Feature Request
            Reporter: Bela Ban
            Assignee: Bela Ban
            Priority: Minor
             Fix For: 2.6.8, 2.7


If we have UDP.mcast_recv_buf_size="50000000", but net.core.rmem_max is (by default) 131'000, then we issue a warning that our mcast_recv_buf_size is clipped at 131000.

Unexpected small receive buffer sizes lead to worse performance
