When I test a program on mac and Linux server, valgrind gives different results, where valgrind on mac said there are some possibly memory leak. Could anyone explain why? Thanks a lot.

I am currently running a VB application through mono on Raspbian. After a bit of troubleshooting the program boots and appears to be running quite well. However if left to itself for a few minutes the VB application just shuts off. This program runs excellently on the windows pc for any duration. Barring this being an issue with the VB code itself is there any major PI related issues that I may have missed in setting up mono? I set up mono the usual way and am launching via "sudo mono app.exe" in terminal.
Thank you for any insight you may provide into this!
UPDATE: mono just FINALLY threw out an errot to me System.OutOfMemoryException : Not enough memory to complete operation [GDI+ status: out of memory]
UPDATE2: Memory leak, its a code related issue.
Hi to anyone else that runs into this issue. For us it was a memory leak.
I home host a Minecraft server and I just updated Java to update 65, the server worked perfectly before updating but now, it says
"This Java instance does not support a 64-bit JVM. Please install the desired version."
Installing 32-bit Java doesn't help and this also happens when I run my Minecraft client.
I have 64-bit Windows 7 running 64-bit Java 7.
If anybody can help that would be great.
EDIT: Fixed it, apparently I'm just an idiot and had 32-bit installed when I updated java, and since I thought I had 64-bit installed I never thought to re-install it. Sorry for wasting your time
As the author stated, the solution was pretty simple. Bringing it to an answer to help future users
This java instance does not support a 64-bit JVM
This error is associated with your System looking for a Java 64-bit Virtual Machine and not finding any.
To solve it, you must make sure that the 64-bit Java is installed. The problem the OP had was: He assumed he had the 64-bit installed, but he did not.
To download Java, access Java Website
Because you are using 64 bit minecraft client, you are not able to work even with 32 bit JVM.
Kindly install all the things, mincraft server,client, JVM of 32 bit only. You can run it definitely. If still not able to work, let me know with exact error message you are getting.
The latest version of valgrind available is 3.9.0 which supports Mac OS X 10.7. I have Mac OS X 10.9.2. I've just begun learning C programming and I need valgrind before I go any further.
Had anyone successfully ran valgrind on Mavericks??

Trying to run valgrind on my application.
I have copied the valgrind executable file (based on ppc compiler) into a machine based on intel compiler(i686).
I am stuck after this .
I have tried googling for the same but did not come across any standard document.
Can anybody please help? Just a nudge in the right direction ....
Yes, one of my processes running on PPC machine crashed. Wanted to check for memory leaks in that process. But the available valgrind is for x86 machine.
As i know java programs are able to run on any Operating System.
and there are JVM's for any kind of machines.
I need a JVM that runs on my PC stand alone, and not on my OS (windows or any thing else).
I mean a JVM that acts like a boot, instead of the OS boot
i searched for all versions of JVM on "www.java.com/en/download/manual.jsp", but i did not get the suitable JVM.
the following link helped me a little but that was not enough
http://java-virtual-machine.net/other.html#jvm
my PC CPU is AMD Athlon(tm) 64X2 Dual Core Processor 5200 + 2.69 GHz
any body can help me to find the suitable jvm version ?!
Sure, have a look at JRockit Virtual Edition. As I understand it it's basically a micro kernel especially tailored for the JRockit VM.
From this page:
Java without the OS: JRockit Virtual Edition (VE)
Am I the only one that's never heard of this before? The Oracle JRockit team is looking at eliminating the OS from the stack required to run Java. This product will be called JRockit VE (not out yet)
JavaOS
Good lucking getting hold of it, though, it's nothing more than a historical curiosity.
There are two JVMs that I am aware of, which have this property:
The Fiji WM: http://www.fiji-systems.com/index.html
According to http://rtjava.blogspot.com/2009/11/new-real-time-vm-was-born-fiji-vm.html it also runs on bare metal.
The next possibility is JNode: an open source operating system where most parts are written in Java (the rest in assembly): http://www.jnode.org/
JNode is still beta, though.
No.
There was an idea of making a machine that could run a JVM as an actual machine (non virtualized), similiar to LISP machines, but that idea never took off...
You need a host OS to run a JVM.
Googling "java real machine" might give you some interesting articles.
I've found two: one from 2004, talking about how such a machine could be built and another one, talking about how JVM runs as a real machine on hardware such as mobile devices.
Still, no dice with a plain PC.
