9649 mem leak?
« on: June 07, 2009, 12:09:01 AM »
been using amuled for ages now and it never normally goes above 30-50MB (on heavy load) but ATM im only uploading and i've logged back into my nix box and its nearly 350MB with only 600 on queue,
for my config, this is not normal.

gav616, are you one of the blessed ones with insane upload rates (> 1 MB/s) ?

Can you try to watch memory usage through a script and match it against the logfile to see if it raises continuously, or when certain actions happen?
Did you compile with mmap or without?

yeah, strangely enough its the first time i noticed and enabled 'mmap' at build, i will disable this, as i think now this was the leak..

gav616,
I see that running amuled for a long time (>1-2D),  the memory usage tend to reach a steady state.
So, against what I said previously, I currently don't think there is a 'leakage'.

Absolute memory footprint is another story, and it depends on several factors: number of connections, downloads, shared files, clients, IP filter enabled or not, and so on.
Looking at your last post, I'd say that in your running conditions 100Mbyte footprint is appropriate.


ah, ok, thanks for info.

Can one of you please try aMule instead of amuled to see if it has the same memory usage?
And please also try amuled with optimize and without debug.
Of course memory use is supposed to rise over time (with KAD tables building), but I think amuled is using way too much memory here.

What about amuled 2.2.5 ? How much memory does it take ?

Thank you very much for making these tests for us. So it's probably nothing introduced recently.

Some other things to test (individually, just with SVN and either with or without SVN as you like):

- remove your known*.met (back it up and restore it later)
- disable Kad

known.met: I thought a BIG load of known AICH hashes might be part of the problem. Well, seems not to be.

I can't say what Kad does when it gets disconnected (maybe it doesn't free its internal tables). Please try to disable Kad and then restart the client and see how memory behaves then.

I wonder what hogs all that memory.  ???

KAD is supposed to store data about other nodes, who has which file and which keyword results in which hash. And this data raises with time as more information is being published, reaching some maximum. No idea how much memory it's supposed to take.

I'm rather surprised how much memory it takes without Kad. I think I should do an analysis how much the different data structures take, and how big they grow, but that takes some time.

Freddy77 did a lot of memory analysis, but I can't say if he's still around.

Could you possibly run amuled with the Valgrind heap profiler?
