    Hi Alexander,

    Thanks for the profiler log. From looking at that, it could be that you are running out of memory and there is not enough available for Profiler to use to process the results. Does the Profiler still work if you do not perform as many operations with the software that you're profiling? This may be a sign that you simply need more memory.

    Please let me know your thoughts on this.
  • Hello, Brian.

    No, I don't think this is memory problem. I tried to take snapshot
    right after application start, on login dialog.
    When exception is thrown, aspnet_wp process is taking 60 mbytes,
    ui RedGate.Profile process - 38 mbytes, service RedGate.Profile process - 9 mbytes. I am running windows 2000 with 512 mb of memory.

    One more error - if I close IE window after exception (instead of clicking profiler STOP button), dialog with following text show up -

    Unable to create profiler results Index was outside the bounds of the array.

    Hi Alexander,

    When you stopped profiling, ANTS Trace Log indicates that you have only 26MB of physical memory available. We're putting some code into the next version to handle these low-memory situations.

    In version 2 of ANTS Profiler, the STOP button merely stops the profiling session without returning results as opposed to 1.x, which would cause results to be produced. So I can imagine that clicking STOP wouldn't cause the problem to surface.
  • Hello, Brian.

    How much free memory do I need to profile?
    Here's another log:

    Hi Alexander,

    The amount of memory you'll need depends on the size of the results. That's why it would be a good idea to try doing a bit less in the profiling session and taking a snapshot to see if it works with less data.

    ANTS Profiler 2.5 now detects low-memory situations and handles them a lot more gracefully. Low memory should no longer kill the profiler and raise exceptions.
