Process instances are getting cancelled Automatically

exception is set to 12 days.  process started at 6 th may 

That view is still not the whole process model, neither is it in a cancelled state (the UIT is still marked as active). 

Im not sure if i can share the whole process.i will try to debug the issue and let you know.Thanks for your time

You can perhaps share a bit more detail - when you say "processes are getting cancelled automatically", what exactly do you mean?  How do you know?  What are you seeing, versus what were you expecting to see?  The screenshot of a running instance above is not a process which got cancelled in any respect, hence Stewart's reply above.  If you provide more info for us to go on, we could help troubleshoot or at least attempt to clear up any confusion you might be having.

i just put a filter on monitoring mode.Then i got few instances.after  that i opened the instance and checked the flow it was stuck in user input task.

1)Initially i thought in somewhere in the process "Cancel process smart service" is triggered and it killed all active process then i checked the entire flow there was no sign of it
