There is Insufficient Memory for the Java Runtime Environment to Continue Ggservers

Thread Status:

Not open for further replies.

1. Hiya I need some help with my minecraft bukkit server that i run off of GGServers hosting website. Im running the beta build of bukkit for 1.7.9 and My server crashes a lost when nobody is on it. Here is the error I get and note I have the most updated version of JAVA and I allocated 2 gigabytes of memory to the server out of the 5 gigabytes I have on it or the 16 gigabyte RAM on my computer.
   8.08 22:14:56 [Multicraft] Looks like a crash, check the server console. Return value: 1
   08.08 22:14:56 [Multicraft] Server shut down

   And I dont know much about JAVA But here is the Error report

   # There is insufficient memory for the Java Runtime Environment to continue.
   # Native memory allocation (mmap) failed to map 1789394944 bytes for committing reserved memory.
   # Possible reasons:
   # The system is out of physical RAM or swap space
   # In 32 bit mode, the process size limit was hit
   # Possible solutions:
   # Reduce memory load on the system
   # Increase physical memory or swap space
   # Check if swap backing store is full
   # Use 64 bit Java on a 64 bit OS
   # Decrease Java heap size (-Xmx/-Xms)
   # Decrease number of Java threads
   # Decrease Java thread stack sizes (-Xss)
   # Set larger code cache with -XX:ReservedCodeCacheSize=

   And the Rest of the crap

   Just Note I have no idea what im doing with any of this information and if you tell me to do something it must be in stupid terms

   Any help would be appreciated thanks anyone and all

2. I'm not that experienced in Java, but it looks as if you are using a 32-bit Java. 32-bit OSes (even though it seems you have a 64-bit OS), along with Java, can only support 4GB RAM, so try upgrading to 64-bit, or going into the run.bat and allocate more RAM this way.

3. I am highly confused by what you just said. 2GB out of 5GB or 16GB (that makes no sense)

   Are you running CentOS inside a virtual machines on your PC and trying to run Craftbukkit inside this virtual?

   Here are the key tidbits that I could gather from what you posted:

   Java Error: There is insufficient memory for the Java Runtime Environment to continue.   Server Startup Command: /usr/java/jre1.8.0_05/bin/java /home/minecraft/multicraft/servers/server609/jar/craftbukkit_beta.jar nogui -Xmx5120M -Xms5120M -Djline.terminal=jline.UnsupportedTerminal   Operating System: CentOS release 6.5 - Linux 2.6.32-358.el6.x86_64   Total Memory: 74,237,796 kB   Minecraft Server: Craftbukkit 1.7.9 BETA                        

   It seems like CentOS "thinks" it has 74 GB of RAM! Or is this hardware info from a hosting company that is sharing this server to many Minecraft server owners?

   You should know that "the latest Java" is NOT what you should be using to run Craftbukkit. There are issues with Java 1.8 since Minecraft/Bukkit were compiled against 1.7 and not optimized or made compatible with 1.8 yet.

   I recommend downgrading Java to Oracle Java JRE 1.7.0 Update 65 (make sure it is 64-bit by typing "java -version" at the command prompt or specifying the full path to java when starting the server)

   The startup parameters show 5120M (5GB) being given to Java to run the server. If Java is 32-bit, it will never work. It will only work if the Java you are calling is 64-bit (and it can be since your OS is 64-bit)

   If CentOS only has 5GB allocated to it, it cannot give 5GB to Java.

   As a test, change the startup line to only give 1024M to Java and see if it loads up. If that is not enough (e.g. you have tons of plugins) then try 1536M
