Photon and dumper

Hey all,

We are having a problem with one of our applications during run time.
The app runs with Photon1.12 and QNX4.24. At present Photon will
die for some unknown reason and at different time intervals. We would
like to find away to log what Photon is doing during run time to
determine
what is happening and why it dies. We thought of using dumper, but
I do not believe I will get any useful information from this approach.

So

  1. Is there a way to run dumper with Photon and get good
    information.

  2. Is there some other function or program I can use to get
    information about what is going on.

  3. Is there a third party app that I could use.

Or anyone got any other suggestions to find out why Photon dies.

Thanks

John

Photon may not be dead. You may be running something at very high priority.
Can you move the mouse? Do you have a PTerm window open that you can type
‘sin’ at? I usually have a Phindows connection to my QNX 4 machine, just in
case I do something stupid that locks up Photon.

We can telnet into QNX. The sin response shows that Photon is not preset (slain)
in some un-known way. PWM is also gone, however phfontpfr is still running along
with Mouse and Input. The mode switcher process is also gone ( in our case
chipsbios.ms & Pg.chips). The parent application is gone but the child process
is running. Because the child is still running the information in the tracelog
is from the child and does not indicate the cause of the photon death. The child
has been assigned as parent.
