Attempting to get Stardog working on an Amazon EC2 instance for both Ubuntu 16.04 and Redhat Linux and encountering the same issue on both.

Steps to Reproduce:

Using Ubuntu 16.04  
Installed Java 8 and added as export JAVA\_HOME=/usr/lib/jvm/jdk1.8.0\_141/  
Set export STARDOG\_HOME=/data/stardog  
Unpacked the stardog-5.0.2.zip into /data/stardog.  
Moved the license into /data/stardog.  
Set ownership of /data/stardog to user running start command

Using Redhat Linux 7.4  
Installed Java 8 and added as export JAVA\_HOME=/usr/lib/jvm/jdk1.8.0\_141/  
Set export STARDOG\_HOME=/data/stardog  
Unpacked the stardog-5.0.2.zip into /data/stardog.  
Moved the license into /data/stardog.  
Set ownership of /data/stardog to user running start command

When I attempt to run stardog-admin server start I get the same error in both instances. I am attaching the entire error log as a text file.

Any ideas?

This is most likely because you are trying to run Stardog on a machine with less memory than Stardog is setup to use by default. The default memory allocation for Stardog is a 2Gb heap and 1Gb offheap and can be changed by setting the following environment variable.

`STARDOG_JAVA_ARGS="-Xmx=2g -Xms2g -XX:MaxDirectMemorySize=1g"`
