Hey guys,
Can you reference any articles/FAQ's that deal with the following questions:
1- Does the modern unix kernel (ie. FreeBSD, solaris, linux) implement Memory
Allocation Accounting (MMA)? In my mind, an MMA system would keep track of how much
memory each process has "checked out" and returned since it began running. So if a
proccess checks out 512MB throughout it's lifetime, and only returns 256MB before it
dies, the kernel would have a record of this. And there would be some command line
tool which enabled users to access this accounting information.
2- If modern kernels do not implement MMA, can this info be retrieved by sifting
through the /proc filesystem? (perhaps i could put together a system memory
allocation map using perl to sift through the /proc data?)
3- If i were able to determine that a process had died without returning all of it's
memory, does the modern unix kernel provide a mechanism that would allow me to
retrieve/recycle this wasted memory?
If these are stupid questions, or if there are some elementary kernel design
principles that preclude the MMA functionality as i have described it, please
enlighten me. Many Thanks in advance for any comments/suggestions.
best regards,
