Memory Leak

xerka · 07-15-2003, 12:53 PM

Well after looking at one of my clients memory usage and seeing that it was up over 150mb! I found this thread over at the distributed folding site http://www.free-dc.org/forum/showthr...?threadid=3385 . Apparently there is a strange memory leak. Some of the people think its because of how the progress.txt and filelist.txt get updated. A few of the guys have noticed for a temporary fix that they can change progress file to update either not at all or greater than 10 times(use the -g 0 option or -g 10 or edit if you are running it as a service edit service.cfg to 0 or 10). You can also leave the default but you probably need to restart once the mem usage gets too high. Have any of you guys noticed this problem?

MMine's up to over 300 MB though I am running a gig of RAM and it had been folding for the last week (well 161 hours) continously so I don't thoin that counts.... but the memory usage HAS been steadily rising. If I hit 900MB RAM usage I may restart it but it ain't bothering me.... yet.

The clinet is supposed to use a maximum of 150megs. If it is over that then it's probably just going to worst.

I have kept an eye on that thread for a few weeks now and they are stumped so far.

I have not had a problem at all yet with memory on my 3 comps. 1 ran for a week strait untill last night and it was still below 90megs. if it was a true memory leak it should be happening on ALL computers and not just some of them. It is weird stuff....

This client in general is pretty weird. I was over 100,000 a day yesterday and now they are struggling to put out a 1,000 an hour.... One comp is taking over 2 hrs a structure! Usually it takes 10-15minutes. Worst part is the energy level is in the 8's. Not like all that wasted time is doing the project any good....:shrug:

I think the two instances are related... I was running a low memory (just over 100MB) when I was getting over 90,000/day.. and recently now I am running 25k I am using 300MB.

In programming terms it is a memory cumulative loop that tales more and more time to do each cycle e.g.

for (beginng till end) {
read buffer
anylyse buffer
add large amount of stuff to buffer
}

That would explain each phenomenon, though I think I could be way off its the best theory I could come up with. (needs more reserch)

1. Please remember it is normal for memory usage to go up DURING a generation - but it should get 'flushed' at the end of a generation (if you keep it going)

It doesn't say HOW LONG a generation is... it could be 3 days. that would explain it (and also prove my theory

).

I just got home and noticed my main rigs memory was down to 6% left!

Also have another rig that has the laxness levels at 57% 85% 100%! That one, if the explaination is correct, should be crunching like a mad whore soon!

I'm up to 320MB now.

God I hope I'm right.
