Resolution

To resolve this issue, increase the vco.socket timeout value.

Ensure there is a valid backup before performing any changes.

1.  On each of the vRealize Automation appliance nodes, edit this file:

/etc/vcac/webapps/o11n-gateway-service/WEB-INF/classes/META-INF/spring/root/o11n-gateway-service-context.xml

2. Change value on this line from 30 seconds to a higher number:

<property name="socketTimeout" value="#{vcoConfig['vco.socket.timeout.millis']?:30000}"/>

For example to increase timeout value to 60 seconds change the line to match below:

<property name="socketTimeout" value="#{vcoConfig['vco.socket.timeout.millis']?:60000}"/>

3. Restart vcac-server with by running command:

service vcac-server restart
