EZD1310I

Explanation
 An unusually high rate of inbound sysplex-distributed
traffic resulted in  severe contention for internal TCP/IP resources,
as measured by the maximum  concurrent service request block (SRB)
threshold.  TCP/IP discarded inbound  sysplex-distributed traffic
that is associated with the SRBs that exceeded the  threshold to protect
the system from exhausting critical resources.  This  message is issued
once per  sysplex monitor interval if the concurrent SRB  threshold
is exceeded.  The message is deleted after an entire monitor  interval
passes without any SRBs exceeding the threshold. 
 In the message
