IBM Business Automation Workflow (BAW) and the Insufficient Memory

I'm just getting to grips with the (relatively) new package, IBM Business Automation Workflow (BAW), which includes new ( to me ) ECM capabilities such as Content Navigator.

Having installed the binaries: -

com.ibm.cic.agent_1.8.9001.20180709_1302
com.ibm.bpm.ADV.v85_8.6.10018001.20180628_0740
com.ibm.websphere.ND.v85_8.5.5013.20180112_1418
8.6.10018001-WS-BPM-IFJR59569_8.6.10018001.20180829_1311
8.6.10018001-WS-BPM-IFJR59939_8.6.10018001.20180905_0257
8.6.10018001-WS-BPMPCPD-IFPD59569_8.6.10018001.20180829_1322

and updated the Deployment Environment (DE) properties file, I started to create the DE: -

/opt/ibm/WebSphere/AppServer/bin/BPMConfig.sh -create -de ~/Advanced-PC-ThreeClusters-DB2.properties

This ran for a while ( whilst I was out at lunch ) and then borked with: _

...
The HTTP and HTTPS ports for server MEClusterMember1 on node Node1 are added to the virtual hosts list.
The HTTP and HTTPS ports for server AppClusterMember1 on node Node1 are added to the virtual hosts list.

with no other obvious symptoms.

Working on a hunch, I checked the free memory on my Red Hat Enterprise Linux (RHEL) VM :-

free 

              total        used        free      shared  buff/cache   available
Mem:        1865252      482608      972292        3200      410352     1194476
Swap:       2138108      726300     1411808

Using the assumption that 1.8 GB may well NOT be enough to build the DE etc. I quadrupled the RAM in the VM, and rebooted.

Now it looks better: -

 free 

              total        used        free      shared  buff/cache   available
Mem:        7992312      543908     6665304       59204      783100     7115580
Swap:       2138108           0     2138108

More importantly ….

Coincidence ?

Methinks not !
