I'm hosting a java server application on a Linux Root-Server.

My problem is, that sometimes the server takes more RAM than the allocated maximum, which leads to an automatic process kill (crash).

That's my start-script:

nohup java -Xmx900m -Xms900m -XX:MaxPermSize=128m -jar -Xss1m jar-file.jar &

As you can see, I also set the minimum and maximum RAM (-Xms900, -Xmx900m), so there shouldn't be a problem.

Does anyone know what I'm doing wrong? If yes, please tell me and show me an "improved start script".

Best wishes, Ishidres

In fact Xms and Xmx determine the lmit of the heap size but there other memory regions : Stack (Xss x Number of Threads) + PermGen + CodeCahe (48MB by default in Java 7 ) + Direct Memory.

In general,those add approximately 1/2 GB if there no specifications.
