Now, your question is quite vague. What is your ultimate goal? For finding the process(es), you already named the ps command - does it do what you want or are you stuck somewhere?
If you want to go further, analyze and correct the program / application - which is the way to go - there's more than one command necessary. You need to dig deep into the run time environment, the input data and channels, and eventually read and understand the program's source code. Be prepared for a lengthy process for "fixing" the culprit.
