paging while still 24GB available RAM

    Same old, same old ... and none the wiser.
    I've actually removed my pagefile completely. I'm still running low on memory while I have over 20gigs available.
    I have tried the process lasso before I started playing the game and all I'm seeing is that the priority of the game has been lowered because it could affect the responsiveness from my system. The same popup comes up for low memory, the game gets windowed, I see a message in my eventlog, saying I'm running out of virtual memory and now it leaves me to wonder what it means with virtual memory. Since I've removed my pagefile (or set it so 0MB), do I still have some hidden virtual memory somewhere?
    So far I have no issues running without a pagefile so I will continue to run like this, however, the problem isn't solved. The good things is though that the "leak" isn't consuming all of my ram.

    running out of virtual memory
    Historically that type message has meant the Paging File or Swapfile was not large enough. I usually solve the problem by adding a second HDD and putting the Paging File on it at the recommended 1.5 times the physical RAM [in Help on the paging file]. I've always noticed a performance improvements doing it that way, so far I've not needed to increase it.

    After a night's sleep and re-reading this I should have added that I set the maximum and minimum sizes as the same, prevents fragmenting of the paging file on the HDD.

    I believe in this case "virtual memory" refers to the private virtual address space of the process. As far as applications are concerned that is what "memory" is. This is referred to as "virtual memory" and is all applications ever access. Applications know nothing of RAM or pagefile.

    I don't believe this issue has anything to do with the amount of RAM present or size of pagefile. You could likely have terrabytes of both and still have the problem. I believe that some 32 bit process is exhausting it's private address space end that is why the problem is occurring. That is why I suggested a screenshot of Resource Monitor showing the memory tab sorted by Commit. This value is very significant and is not currently being displayed by Process Lasso. It isn't a very useful program for this kind of problem.

    Historically, you are right, that the paging file should be 1.5 to 2 times the amount of RAM. With the recent amounts of RAM generally found in even desktop systems, this has become a completely ridiculous rule. The moment you are using even 1 time the amount of RAM in paging (e.g. an 8GB RAM system), you have a serious problem on your system and unless that paging file is located on a super fast SSD drive, you're going to have a ridiculously slow system.

    Thanks for hammering this into me I'll update the thread in a moment with the requested info.

    I see that VirtualBox. is running. Were there any virtual machines running and if so how much memory was assigned to them?
    Also not seen before is the very large commit charge. On a 32 GB system that would mean a commit limit of at least (or very close to) 32 GB. So much commit would indicate very high usage by a process, not visible in the display, or usage by a virtual machine.

    The Watch_Dogs_3dm process has very high commit but not nearly high enough to explain the situation. Is this a 32 or 64 bit process? Was it running under a virtual machine?

    No, I've got 2 Ubuntu servers running in VirtualBox. One has 8GB assigned, the other 4GB.
    The problem does not seem to be related to VirtualBox however. If I'm not running my VMs, I'm still getting the same problem with watch_dogs (which is a 32-bit app). The memory problems I'm getting are usually with utorrent or watch_dogs.
    VirtualBox is completely 64-bit, both software and VMs that are running. With VMware Player, I got some memory leaks where it was using all of my RAM with the same 2 machines running, that's why I switched to VirtualBox and I've never had a memory issue with it again since then.

    On superuser.com, I was reading a bit about the virtual memory as well. I didn't quite understand it, but they were talking about 3GB of private space for 32-bit applications, and something about AWE and something else to increase the space? Anyways, those were developers talking and I had a hard time understanding even half of what they were going on about. I noticed that watchdogs was using about 3GB of private space too.

    Now that I'm watching it again ... I do see what you mean with the commit charge running at the full 100%. I have to say, I took the screenshot after I received the error and the commit charge seems to have dropped by then. Next time, I will alt-tab before I get an error and see what the real-time values of the applications are then.
    I'll keep you posted!

    With a 64 bit OS the virtual address space of a 32 bit process is normally 2 GB, 4 GB if it is Large Address Space Aware. I would guess that it is but cannot be sure. 4 GB is a firm limit. 3 GB is the limit on a 32 bit OS, but only if a specific configuration is in use. AWE is not a setting but a programming technique. It is not simple, has numerous restrictions, and is not commonly used. Not relevant to you.

    I do find it hard to believe that a 32 bit process that is Large Address Space Aware would have issues on a 64 bit OS. It seems unlikely that it would run at all on a 32 bit OS.

    Most likely the cause is whatever caused the 100% commit charge.

    The fact that you have uTorrent is a serious concern. Torrent sites are notorious for spreading malware. And it is not always found by anti-malware software.
