What is your kernel version? Did you update to the latest kernel?

Was using 2.2.6 release - Tried downloading the latest and rolling my own but I'm hitting upnp problems when trying to compile using 10400. I haven't been able to resolve whats causing this as yet. Kernel version 2.6.35-23 generic amd 64. Currently posting this on -22 and will try aMule to see if it crashes on this as well.

Ran it for a week on -22 - no issues. Ran 10400 on -23 and ran into every expanding memory error within 2 hours. Unable to do a backtrace as waiting for the ~1-2 hours for the HDD to stop thrashing (swap) is not me. I use the button on the front.

Please run a top in parallel to see if the memory runs up gradually or in a quick surge.
If it's gradually, maybe you can run it with valgrind's memcheck to see where it leaks?
A backtrace is useless anyway in an out of memory condition.

Runs up slowly to start with then accelerates in a burst - got a link to running a top as I have never done that before.

Just open a console and run top  :D
Equally simple question - how do I roll back to an older kernel (and then forward to a newer one) ?

In Ubuntu you can do that easily using StartUp-Manager - see here:

I have the choice of the last couple of kernals when booting (at grub stage) just in case the newer one is cack for some programs or just cack, so I use it on occasions. With regards top should I pipe it to a file. Usually once the mem problem happens I cannot regain control of the system as i/o is flooded and hogs all resources.

OK. Can you try a few things to help track the problem down:
- Try latest SVN. I have plugged a memory leak in 10417, though I doubt it was The Big One.
- Try amuled with amulegui instead of amule, to see if it makes a difference. If it crashes - which of the two uses up the memory?
- Try amule but disable Kad, use only ED2K.

I'll run the latest SVN for a couple of days and see what happens on kernel 24 :)

By the way, I've written about the problem on the Ubuntu forums - even if there's no reaction from Ubuntu developers, at least the aMule users who go there to look for a solution will be able to find it.

Ran the release build on -24 and it chews up the memory but slower and is non-responsive (i/o bound) after a while. Going to compile the latest -svn soon and try it out

OK, I've been running SVN 10424 on the -24 kernel for a few days now and there were exactly zero crashes in that time. HOWEVER, I only have a few small (a couple hundred megabytes each) and rare (less than ten sources) files in my download queue. I'm going to add a huge and very popular file now and we'll see what happens :)

Well, when I came back home my GNOME was dead which means that the leak is still present. The file I've started downloading is humongous (almost 8 gigabytes) and very popular (200 sources, my max number) and I'm 100% sure that it is causing the problem. I've seen exactly the same behavior in the past when I tried to download huge and popular files.

I've turned off Kad now - let's see what happens :)
