TXT or software (Python) problem?

[hvn]

Hi,

On 1 of my TXT controllers I frequently experience the problem that after starting the program using the home-made script run_python:

Code: Alles auswählen

LD_LIBRARY_PATH=/opt/knobloch/lib /opt/knobloch/python2.7 $1

the TXT display flashes and nothing happens while the program keeps running. After I kill & restart the program,

Code: Alles auswählen

ps -ef
kill <ps>
run_python <program>

it usually does work. So my question is: is this a problem with Python, with TXT, with my script or a combination?
BTW, so far, I haven't experienced this on my 2nd TXT (which is newer), so I somehow doubt that Python is the problem.
