Description 
TCP needs to allocate the T_ordrel_ind mblk when it needs to
close a connection.  In memory shortage situation, the allocation
can fail.  TCP will then start a timer hoping the situation may
improve later.  But by doing so, TCP is delaying to free up the
memory the connection holds up.  In a severe memory shortage
situation, this can become a "deadlock" issue.
