How to debug a busy process (no response)​

logging​

error occured?

pstack $PID​

whether there are many locks waiting

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.
