Increase the JVM size in the docker ini file. – StackFlowed Mar 16 '17 at 15:53

Not being an expert on Docker, maybe you can pass `JAVA_OPTS` as an environment variable: `docker run -e JAVA_OPTS='-Xmx1g' cygnus-ngsi`. – frb Mar 17 '17 at 06:59

By default, Cygnus configure the JAVA_OPTS with a limited value, you can modify this value updating the JAVA_OPTS variable, so in order that you docker container set this variable when it is building the container you can add inside of the dockerfile of Cygnus the following env variable: ENV JAVA_OPTS='-Xmx1g'
That line allows you a heap of memory of 1Gb.
Another option is that you create the container and after that enter inside of it and check what is the value of JAVA_OPTS and set to -Xmx1g.
