Lots of memory leaks

Every couple of days I notice my system running sluggishly. I look in Activity Monitor and every time Path Finder is using up a huge amount of RAM - normally around 8-12 GB but once as high as 30 GB (I only have 16 GB of physical RAM). When this occurs I am often not using Path Finder at all but just had some windows open in the background. I quit and relaunch Path Finder and my memory usage goes back down until the same thing happens a few days later.

So I relaunched Path Finder and then immediately ran the Leaks module in Instruments to see what was happening. As you can see from the attached screenshot, Path Finder starts leaking memory from the start and the allocations keep racking up. The leaked objects are only around 100 bytes or so, but Path Finder is leaking thousands of them and eventually it uses up all of my system memory.

    Hi Jon, 

    Please choose a .txt file, open Preview module preferences (gear button next to its header) and uncheck "Colorize syntax". 

    Also, it may be worth trying to restore defaults for View Settings (cmd+J).
    Make sure to have "Calculate all sizes" unchecked here. 

    Sorry for the inconvenience. Please feel free to write us back and we will be happy to assist you.

    Best Regards,

    Hi Jordan,

    I don't have the Preview module visible so I don't think it's contributing to this. But I enabled it and then switched Colorize Syntax off. I already had Calculate all sizes switched off.

    I relaunched and can still see the memory usage rising every few seconds.

    Neither of those solutions work. PF has had memory leak issues on and off for years. Frankly, there were better under PF8 but that version is unusable for a variety of other reasons that I went back to PF7.

    And welcomed back the memory leaks. Oh joy!

    Interesting... for me it's been the opposite. PF7 memory usage wasn't bad enough for me to notice and PF8 is considerably worse. But PF8 is largely stable for me and this is the only major issue I have. But that might be something to do with the fact that I'm not making use of the new module features.

    AM running PF8 8.3.6 on OS 10.12.6 with 64 GB of RAM ... and i get errors that am running out of RAM .. and i see that PF is using 54GB of RAM !!!!!!

    on OS 10.13.6 8.3.9 PF8 i have 16 GB ram in the MacBook .. and PF uses 386 MB

    I will update PF on the MacPRo (64 GB) and see if this helps ..

    This is rather astonishing though .. i just discovered this today .. I hope it can ve resolved becasue i really like PF8 in spite of the issues with the newer versions ..

    Hi Jon,

    Could you send us a sample (a snapshot) of PathFinder process in a separate file - this will enable us to analyze what happens with the application. Here's how to get it:

    1. Open Path Finder and reproduce the problem.
    2. Open Activity Monitor from the /Applications/Utilities folder.
    3. Select Path Finder in the process list. To help making a selection, type "Path Finder" in the Filter field.
    4. Click the Sample Process button in the toolbar - this will open a new window entitled "Sample of Path Finder" and a sample of the process is collected.
    5. Click Save and save the sample file.
    6. Close (Command-W) the Sample window opened in step 2.
    7. Send the sample file saved in step 5 to us.

    Looking forward to your reply.

    Best Regards,
    Jordan
