Is /elex/katscomm the correct executable?

>Load module /elex/katscomm has been stripped.

What did you use to strip katscomm? Did you use a foreign devil strip?
What do these show:
elfdump -S -h katscomm
elfdump -S -o core_200510_hp2

What OS version are you using?
You could download WDB 6.1.

[AQadir_1]

$ elfdump -S -h katscomm

katscomm:
elfdump: The file katscomm is not a valid elf object




$ elfdump -S -o core_200510_hp2
