What you need to do is to run the process under Valgrind. If the process normally runs to completion, you can just run it under Valgrind (by default, the memcheck tool will be used, add --leak-check=full and possibly --show-reachable=yes). If the process is running aas a daemon, then your best bet is to run it under Valgrind and then attach gdb to it and use monitor commands to check for leaks. That is documented on the Valgrind web page, here https://valgrind.org/docs/manual/manual-core-adv.html#manual-core-adv.gdbserver-commandhandling .
