A job with no call stack

Hi everyone
We are on V7r1
Just recently, we had a problem with a particular job
The reason for this problem was discovered and rectified
However, in analyzing this job, I discovered the following

The job would be started, then looking at that job in WRKACTJOB, taking option 5=Work with, then option 11. Display call stack, if active
What was displayed was the Job name, user, Number, Thread, but under the sub-heading showing Type, Program Statement etc.
Nothing
And it can remain that way for a while
Option 14. Display open files, if active would show some files
Option 10. Display job log, if active, on job queue, or pending would show the job log
Also - when taking option 11, it would be take about 20 seconds or so before moving into the call stack entry screen

Eventually - sometime after 2 minutes - the call stack would show the programs etc (hitting F5 a number of time)
The program itself retrieves some system values, data areas, uses OVRPRTF's, CHGVAR's, CPYF's, CLRPFM's
Until it eventually calls one particular program - even then, the call stack isn't displayed until it's a ways into this program


For curiosity if nothing else - anyone have any idea's as to the cause of this?
