find memory leak of a running process​

cat /proc/$pid/smaps

  1. find out the PID of the process

    ps -aux

  2. capture /proc/PID/smaps and save into some file like before_meminc.txt

  3. wait till memory gets increased

  4. try again step 2

  5. find the difference between first smaps and 2nd smaps, e.g. with

    diff -u before_meminc.txt after_meminc.txt

  6. note down the address range where memory got increased

  7. use pstack and watch command to get the right call stack

    watch -n 1 'pstack $PID | tee -a $PID.stack'

    C-c when we caputred right stack

  8. check our stack file, find the functions between address range which we got from step 6.
