I have installed patch 2922 and the aplication
crashes less times and without halt the machine
However, I am still confused, am I doing something wrong
or does the Onyx2 need aditional patches ?
I am sure this section of the code I am sending
as attachment is related to the problem since without
performing that code it never crashed.

attached mail follows:
I have removed the traversal that aplies the gstate
to every gset and it does not crash.
I have attached the source code. Would you help
me to debug it ?
Note: Neither of the versions in geoset_apply_geostate
(commented and uncommented) are crash free.
Best Regards,
Joaquim
