For memory-leak problems you might also use:
ipcs # shared memory or other IPC leaks
xrestop # X resource leaks
memstat # memory usage by process and file

Lots of "development" tools can also be useful for finding crashes or
memory leaks:
gdb
valgrind

glibc also has some environmental variables to help find (or work around) buggy usage of malloc/free:
MALLOC_CHECK_=0 # heap corruption ignored
MALLOC_CHECK_=1 # heap corruption printed to stderr
MALLOC_CHECK_=2 # heap corruption causes abort()

Also, just doing ls -l in /proc/<pid>/fd can be enlightening when trying
to figure out what a program is doing.
