Situation
Cluster master node abends a few minutes after a
backup has started.
You will see the following in the abend.log:

Packet Receive Buffers have reached its maximum.
Resolution
By default Syncsort Backup Express distributes the
catalog information traffic via the node running the
Master_IP_Address_Resource. This will cause excessive traffic and
also will cause the Packet Receive Buffers to increase. Due to the
fact that the server will not receive enough or timely Packet
Receive Buffers, the server will stop communicating via the
NIC.
Backup Express now has the ability to distribute the catalog information traffic across cluster nodes hosting each volume, thus reducing load on the Master IP node. To enable this functionality, add --enableehdproxy to the SYS:\ETC\SSEVTHND file on all cluster nodes.
