Question

Insufficient memory for Java Runtime Environment

Hello, I am testing deployment of a JEE application to a droplet with 512MB, and as I start the application server Wildfly (JBoss AS), I received this message:

3:42:45,663 INFO  [javax.enterprise.resource.webcontainer.jsf.config] (ServerService Thread Pool -- 75) Initializing Mojarra 2.2.11-jbossorg-1 20150505-1501 for context '/bbword'
Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000e2320000, 37601280, 0) failed; error='Cannot allocate memory' (errno=12)
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (malloc) failed to allocate 37601280 bytes for committing reserved memory.
# An error report file with more information is saved as:
# /opt/wildfly-9.0.0.Final/hs_err_pid761.log

Is there really a sign of memory in the droplet, or something else? I can test the same application on Openshift’s free catriage (similar to digitalocean’s droplet).

Ok, Java is a monster that likes to eat RAM. We all know this. First off, confirm this by running top. I did and saw that java was using 58% of my RAM. I just used Java to compile a new jar file for Minecraft to run. Ok. so I ran ps -e | grep java and got the PID and did a kill -9 [PID]. When calling Java I allocate memory for smoother game play [ java -Xmx2G -Xms2G … ]. This sets the ram used at 2GB. Once I ran this again it worked and we are in business. Hope this helps.
