Hi... Following up my own previous post... Basically it indicates expansion of VMA without touching any disks. In this case, there are two possibilities: 1. your script allocates more memory 2. new codes are executed Number #1 is easy to understand, but #2 is sometimes confusing. Codes are read from disk, but how can it be minor fault instead of major one? It happens when the related data/codes are still on page cache, so no need to read anything from disk. The page can simply be taken from the page cache, remapped to the process address space and done. Hope it clarifies your issue. regards, Mulyadi -- Kernelnewbies: Help each other learn about the Linux kernel. Archive: http://mail.nl.linux.org/kernelnewbies/ FAQ: http://kernelnewbies.org/faq/
