Memory leak...

[Netzarim]

I've updated to 3.8.3.340 on two machines this morning. One is using an AMD proc, the other is Intel. On both machines memory utilization fro MultiMiner.Win.exe is spiraling out of control. It is causing the systems to be unusable and freezing. I have the Intel one with me, it is an i7, and currently memory is at 7G on this process... When I left home this morning, the system for the AMD was all but hung with over 4G memory and increasing..

The update was done through the application, not as a download and re-install... I just pulled the latest, and re-installed and still seeing the same problem...

Unfortunately I'm not seeing anything like this on any of the systems I run and develop on. I'll keep an eye out though.

Your best bet is to download the free version of Visual Studio or MonoDevelop or Xamarin Studio and compile MultiMiner and see if your problem persists. If so try checkout out an older commit from Git and try again. Let me know once you've found the commit that causes the problem for you.

I just used Sysinternals process explorer on it. The trouble is in mscorwks.dll!InitializeFusion+0x3410. This thread is where all the memory is being used along with about 20% CPU. Both Systems are Windows 7 Ultimate 64bit. Since this appears to be part of .NET, I updated my .NET to 4.5.2, but still have the same problem.

Now, the AMD system has about 27 devices on it, but the i7 system only has 1, an Antminer USB. But I don't think that is the problem.

I've installed 3.8.1 and I am not seeing the issue. I then installed 3.8.2, and not seeing the issue. I then installed 3.8.3, and the problem returned. I am going to back off my installs to 3.8.2 for now. I am installing Visual Studio and will attempt local compile as well..

Thanks - looking forward to the details. Unfortunately I'm not seeing the issues here. I've run through several profilers and samplers and not seeing anything regarding memory or resource leaks yet.

What is the output of ipconfig on your system?

Version 3.8.3 more accurately scans network devices on your system, which may mean it is scanning a much larger range that previously. However, this should not cause memory or resource leaks in theory.

As an example, I have an adapter in my VM with the following information which causes MultiMiner to portscan 65k IP addresses:

IPv4 Address. . . . . . . . . . . : 169.254.80.80 Subnet Mask . . . . . . . . . . . : 255.255.0.0

If you have an adapter with a subnet mask such as 255.0.0.0 or 0.0.0.0 MultiMiner may be scanning a much larger range, and then starting the scan again (every 15 minutes) before completing the previous scan.

At home I am 192.168.0.x/24. at work I am on a 10.7.27.0/24, so they are all class C subnets - not large...

At home I have 4 network attached devices 3x Antminer S1m and 1x Antminer S3, none at work...

You could test this pretty easily by disabling Network Device detection temporarily and seeing if it affects the growing memory use on your systems:

That seems to have cured the memory issue... I turned them off and on a couple times and restarted each time. The memory goes crazy with it on.. Did not do that in 3.8.2.

Thanks,

Can you please post the output of ipconfig on both systems. Sounds like you have adapters on class B or A subnets.

Working great. Thanks.
