The error you're having says that the server cannot allocate that much memory
to java. So you need to lower memory consumption of build processes until your
system can run them.
In the process of lowering xml, if you get error such as "Java heap space" it
means you are too low. The error you're getting "There is insufficient memory
for the Java Runtime Environment to continue." means you are still too high.
I was able to run successfully the maven build command if Xms/Xmx of 64m, and
both maxmemory in misc/build-runldap.xml set to 32m.
These settings should be low enough for your case.
Regards.
