Specify the amount of heap memory the Jetty web server service should be generated with
next time it is regenerated by the start_funnelback_on_boot.pl script. This effectively sets the
-Xmx option on the jetty process.
The format of the value is as for the JVM’s
-Xmx option, i.e. a number followed by a unit,
m for megabytes or
g for gigabytes.
Note that changing this value will have no impact until the service is regenerated, it’s just specified here to avoid custom values being overwritten within the service config on upgrade etc.
