Maybe your code is blocking somewhere (ie, deadlock)? or a condition
is never satisfied and thus you have an infinite loop?
I don't think it's possible to help you further without having an
explanation of what the code does, or even better, the code.

hi Guys,

I can share the code as it's very huge and complicated but I can brief
you that it is using DB2 CLI API for database interaction.
I have attached the running process to dbx and tryied to track the
problem. Below is the output from dbx:

Waiting to attach to process 1196110 ...

Type 'help' for help.
