Kyr0g Level 1 Level 1 (0 points)

so i'm browsing throught the internet and i get a notification that my startup disk is full and it gives me a list of which applications I can quit. Slightly puzzled (because my desktop is relatively new and I'v only used about 1/3 of my total memory capacity) I quit some applications and continue browsing. I continue to get this error as i browse the internet but at that point it was at 2am in the morning and i had work the following day. I decided to put off the problem till the next day (today). After a good 3-4 hours of usage the same error message popped up! I decided to research it a little bit and I believe it has something to do with this:

    Your problem is excessive swapping of data between physical memory and virtual memory.


    That can happen for two reasons:

    • You have a long-running process with a memory leak (i.e., a bug), or
    • You don't have enough memory installed for your usage pattern.

    Tracking down a memory leak can be difficult, and it may come down to a process of elimination. In Activity Monitor, select All Processes from the menu in the toolbar, if not already selected. Click the heading of the  Real Mem column in the process table twice to sort the table with the highest value at the top. If you don't see that column, select


    View ▹ Columns ▹ Real Memory


    from the menu bar.


    If one process (excluding "kernel_task") is using much more memory than all the others, that could be an indication of a leak. A better indication would be a process that continually grabs more and more memory over time without ever releasing it.


    If you don't have an obvious memory leak, your options are to install more memory (if possible) or to run fewer programs simultaneously.


    The next suggestion is only for users familiar with the shell. For a more precise, but potentially misleading, test, run the following command: 

    sudo leaks -nocontext -nostacks process | grep total


    where process is the name of a process you suspect of leaking memory. Almost every process will leak some memory; the question is how much, and especially how much the leak increases with time. I can’t be more specific. See the leaks(1) man page and the Apple developer documentation for details:
