[beagleboard] Process accounting resumed

[Micka]

Hi,

periodically I've this message in my kernel. Does someone know what is it ?


I found that:

/* * Check the amount of free space and suspend/resume accordingly.
*/static int check_free_space

        if (time_is_before_jiffies

                }
        } else {

                }
        }

        acct

        return acct

does it mean I don't have anymore space available in my linux ?
