I am trying to see which process which is causing a memory leak, and dump the heap which is causing it to see what is the issue.
Which command do I use in gdb to set the memory leak on and check the heap?
I tried:
(gdb) check -leaks
checkpoint: can't find fork function in inferior.
(gdb) help info heap
Undefined info command: "heap". Try "help info".
(gdb) help info leaks
Undefined info command: "leaks". Try "help info".

kmemleak can be enabled in the kernel configuration under Kernel hacking > Memory Debugging. I used to turn it off by default and enable it on demand by passing kmemleak=on to the kernel command line. If some leaks occur before kmemleak is initialized you may need to increase the “early log entries” value.
Go to your Linux command prompt and type “gdb”. Gdb open prompt lets you know that it is ready for commands. To exit out of gdb, type quit or q.
Valgrind is your answer as people have pointed out. Normally, Valgrind will only report errors at the end of your program's execution. You can link Valgrind with GDB (vgdb) to dump Valgrind stats during a program's execution while it's running under GDB.
