Troubleshooting
Java 7 standard edition or newer required
Check you have Java properly installed on your system. If you're on Linux, you may provide the path to the jdk with ./bin/gephi --jdkhome $JAVA_HOME
JVM Creation failed
This error message is due to memory settings, see following section.
Memory
Memory available to Gephi is determined by Java. Less or more memory can be allocated by configuring Gephi’s startup settings. If too less memory is allocated, Gephi will stop running when it reached the limit and you will loose your current work. If more memory than what the system is equipped with is set, Java will not be able to start and return “JVM Creation failed” message. By default, maximum memory is set to 512mo.
To modify memory settings, you need to edit gephi settings file. Modify the value after the -Xmx option to change the maximum heap space. For example, to use a heap size between 256 and 1024 MB, change the options to -Xms256m and -Xmx1024m. If you have Gephi open, you must close and reopen Gephi before new options take effect. On computers with 2GB of memory, you can set -Xmx1400 to get maximum performance.
