    memory usage - overhead

    While troubleshooting some resource issues, I checked the memory usage. With one instance of Stata and nothing running (this is a server, so there're other active users), Stata reports a large amount of memory - about 4GB - in both the allocated and used columns on the overhead line. I can't find an explanation, or a prior discussion, of "overhead" memory.

    Does anyone know what this means and whether this has any impact on performance?

    technical details:
    environment: windows server 2008, x64, running on a vmware virtual platrform
    RAM: 16GB
    stata: stata/mp 14

    Any feedback would be greatly appreciated!

    Do you know the size of the data set being used and/or what the end user is doing at the time?

      it seems to be independent of the data - it shows that amount of overhead even when I check right after logging in and opening Stata - see attached. I'm the end user (the system admins are leaving the troubleshooting up to me). Other users show the same amount of overhead.

        This is a bug. To be precise, it is a bug only in the output of the memory command, not in Stata's memory allocation routines. The output will show the correct values in a future update. There is an update to Stata due to be published today, but the fix will not be in that update.

        The correct values, on my personal machine, are 1,081,344 bytes used of 1,082,136 bytes allocated for overhead. The 4GB numbers were spurious.
