Also, how about the reliability of the output given by 'pmap <pid> |
grep heap'.
Can we consider it as a leak, if the heap size keeps growing?

Btw, can there be any other cause for memory leaks? If yes, the above
way may not be complete, I suppose. Could somebody clarify?

Overall, it is ambiguous about what Simple Solaris commands to use to
find out whether there are leaks are not(rather than using tools)? Is
there any descriptive paper providing complete information on it?
