    What's the exact error they are receiving? Print-screen?
    Thanks.

    PgSp and Paging Space

    Folks,

    I have an admin here who is trying to run a fairly simple command on AIX,
    but after a while, he gets an Out of Virtual Memory error and it dies.

    I changed all the ulimits to -1, that did not help.

    I had him run the command while I monitored the system with "topas". There
    I see that Paging Space never moves from 99% Free, but in the process (ps)
    section of topas, I see that his running process uses 25% of the 4-CPU
    server and, in the next column, labeled "PgSp", the number keeps on
    growing. When it gets nearly to 1024, the process dies.

    So, what is the difference between the Paging Space, ( same thing one gets
    from "lsps -a") that never grows and the "PgSp" in the processes section
    of "topas" that shows it is growing?

    This box is a P655 with 4 GB of real memory and 2 GB of swap.

    Thanks,
