Java.io.ioexception Cannot Allocate Memory Linux


I downloaded the "jdk-6u1-linux-i586.bin" from Sun, unzipped it as root in /usr/local and added it to my PATH. The program is: [[email protected] sisma-acquirer]# cat prova.java import java.io.IOException; public class prova { public static void main(String[] args) throws IOException { Runtime.getRuntime().exec("ls"); } } The result is: [[email protected] sisma-acquirer]# javac prova.java It's a masculine name in Italy :-) –Brian Agnew Jul 14 '09 at 12:03 1 Thanks Brian, I'm a male. –Andrea Francia Jul 14 '09 at 12:36 | show 1 Re: Runtime exec IOException issues 807580 Jun 27, 2007 7:52 PM (in response to 807580) I've continued to investigate this with my discoveries below. news

Cannot Allocate Memory Jvm Normally the kernel will allow a certain amount of overcommit of memory (in the default, heuristic mode - mode 0 if you `cat /proc/sys/vm/overcommit_memory`). Ultimately something fishy is going on with memory, but with seemingly contradictory results, I am at a loss of where the problem lies. Error while executing shell script from java Is there any way to execute a Linux command from Java without fork-ing?

Crate.IO member mfussenegger commented Jul 30, 2013 It seems that the ProcessBuilder which we're using to execute the shell command uses fork() which tries to allocate the same amount of memory If you had you heap set to 1GB and try to exec then it will allocate another 1GB for that process to run.

Also keep in mind that reducing -Xmx aggressively can cause OOMs. Otherwise allowing overcommit is probably your best option.

There are ways to get around this issue by tweaking overcommit settings in Linux, but before you go around tweaking settings, you should consult a Linux expert..

Anyways, if you need more memory, you will need the help of your sysadmin anyways Ron McLeod Bartender Posts: 993 62 I like... edit: Actually, now that I think about it...

You could try to create pipe files (FIFO) and write to them using output_file instead of output_cmd and then read from a bash script that is started separately. Specifying a fixed heap causes the problem, specifying the same size heap with more headroom and it works: ----- [email protected]:~/tmp$ java -Xms2048m -Xmx2048m DoRuntime total: 2075918336 max: 2075918336 free: 2064465248 Exception

Could it be that by setting this very large, fixed heap size as in RUN2, there is no room for the jvm to "maneuver" and properly handle the effort of the Re: Runtime exec IOException issues 807580 Oct 22, 2007 4:12 PM (in response to 807580) I never use the "jpackage" or whatever Linux/Ubuntu's prepackaged java is called.

Please type your message and try again. In our production setup of this application, I adjusted the Xmx setting to be something larger than the Xms setting. What is a satisfactory result of penetration testing assessment? This worked for a period of time, but eventually produced the same results.

Always close streams. The 1.5.0 jvm was not returning the actual errno from the call in the JNI code. Can you post your java version and the output from top (sorted by memory) while elasticsearch is running (before executing the export and while/after executing the export). Otherwise it's all a bit pointless frankly.
