We may also be able to tune malloc via mallopt(). I would guess that mmap()'d data is more likely to be returned to the system so we might try reducing M_MMAP_THRESHOLD from 128K to a smaller amount (maybe try 64K). The flip side of this is M_TRIM_THRESHOLD (which also defaults to 128K). A lower value of M_TRIM_THRESHOLD will result in malloc() returning sbrk()'d memory back to the system more often. So, there are knobs we can twiddle-- I just don't know how likely they are to help. - todd -- This message was distributed to subscribers of the selinux mailing list.
