Memory leak in MT4

I run a lot of instances of MT4 on my old notebook from various brokers and recently I've noticed that they seem to be constantly chewing up more and more of my prescious memory.

I have 2GB of memory on the machine and after leaving the MT4's running for over 24 hours, then my memory consumption climbs to around 1.7GB.

When I close all the instances of MT4 and start them back up again then my memory usage falls to around 0.9GB.

To my understanding it would mean that on average each instance of MT4 leaks a bit over 100MB of memory per 24 hours. Now that's manageable if you have heaps of memory, but if you want to run these things for longer periods of time on a server with more instances, then it becomes a problem that requires constant baby-sitting.

Has anybody else noticed this?

Are there any guys (or gals) from Meta Trader lurking on these forums? Do you guys (or gals) noticed someting similar?

I'm running with the latest builds that were updated a couple of days ago.

I've also attached a graphic from my notebook to show you an example of what I mean.

Try decreasing your maximum chart size. What is your current value?

Keeping maximum history size large isn't an issue for memory I think, but I am not certain.

I run about 20 MT4 instances on a older computer (sempron 2600 or something)... 512MB ram.

never have problems. These MT4s are running EAs constantly.

Also I ran various other EAs and stuff on other computers with just as many instances, for the last year.

So either it is something with the newer build... since I am only on 198, not 200 yet.

or you use features that I don't. Perhaps some indicators I don't use or some custom indicators or EAs. I would test running them with basic functionality then adding indicators or EAs one at a time to find out where the problem is originitating. Then post on the metaquotes site about it once you know what causes the problem, so they can try and fix it.

or could be some other settings like the previous poster suggested.

I do agree that it is likely an indicator or expert. It is very simple to make a mistake with an array and load the entire chart into every element, or add a copy to itself and double the memory usage.

It is unfortunate that I don't know how to see memory usage for each EA and indicator without running debugging applications or heapdumping.
