    Hello,

    Please contact me by email at Support AT NinjaTrader DOT com. In your message please include a link to this forum thread and a copy of the newly created log and trace files for today. (not the abnormally large versions of the files which you were forced to delete)

    The Log file is located in the Documents > NinjaTrader 7 > Log folder and would be named 'log.20140724.txt'. The Trace file is located in the Documents > NinjaTrader 7 > Trace folder and would be named 'trace.20140724.txt'

    Solved

    I was able to solve this by renaming the last log file in ..\Documents\NinjaTrader 7\log
    The latest file was over 3 gigabytes and apparently Ninjatrader was loading this on startup. The log file had thousands of Kinetick connection errors which I suppose occured during my heavy backtesting overnight. Once I renamed the file (in my case from log.20120305.txt to old.log.20120305.txt), Ninjatrader started up right away and memory use went way down to 155 megs.

    Hopefully this helps someone else who might be experiencing the same problem.

    cheers -Dave

    same problem

    Christopher, I have the same problem. Memory usage is over 6 gigabytes on a clean startup (rebooted computer and NT). I was doing some heavy backtesting overnight and this morning is when it happened. My trace file today is almost 7 gigabytes.

    I would like to try to purge the database of the historical data - what's the best way to do this?

    If I did a backup of only my workspace and chart data with no historical tick data, then performed a Restore on that backup, would that work?

    Thanks -Dave

    sent, but one log file and one trace file both exceed 1 million KB and i can't send them to you because of their size.

    started a topic massive memory usage all of a sudden

    massive memory usage all of a sudden

    the memory my Ninja 7 is using is exceeding 2.9 million "k."

    it is slow as hell and everything on my computer has been slowed down to a crawl.

    why is this all of a sudden happening? it used to be operating in the 50-100k "k" range.

    thanks.
