View all process breaks as it's unable to find free memory while it's available

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Setup Java Melody on tomcat and leave it running for 1 days with hits coming 
in
2. Open the Java Melody monitoring home page using url/context/monitoring
3. Click on the link - "View OS processes" It will show the error -"Cannot run 
program "/bin/sh": java.io.IOException: error=12, Cannot allocate memory"

What is the expected output? What do you see instead?
It should show all the os processes

What version of the product are you using? On what application server, JDK,
operating system?
javamelody-1.47.0
Linux
tomcat 6.0.18
java version "1.6.0_23"

Please provide any additional information below.
1. Works fine with server restart for few time and then start breaking.
2. I am sure there is sufficient memory available around 15 GB RAM allocated to 
tomcat.
3. Even Java Melody front screen itself shows - 
   Java memory used:4,311 Mb / 15,134 Mb

Your error does not depend on the memory used by Tomcat, but on the memory 
available in the Linux OS.

So do not increase -Xmx15G, but you can decrease -Xmx15G for a better chance.

Otherwise, see 
http://stackoverflow.com/questions/1124771/how-to-solve-java-io-ioexception-erro
r-12-cannot-allocate-memory-calling-run suggesting "overcommit_memory"
Or try google yourself.

Can we close this issue?

So resolving as invalid, for the reason above.
