Hi,

Thanks for the quick response.

The code I posted is not my actual program and was only to demonstrate
my problem. The complete program I'm writing uses QT and so the loop
is replaced by a Timer event.
I tried out the suggestion. I had already tried the del dcop
instruction, so I knew that wasn't it. I also placed the DCOP variable
outside my loop but that didn't help either.
What I did notice that my program only grew in memory use when the
'ok, Ms = AmarokDcopRes.player.trackCurrentTimeMs() ' code was
executed (or any other function using the AmarokDcopRes variable like
'ok, volume = AmarokDcopRes.player.getVolume()' )
Then I also tried to make my take a pause of a second in the loop but
this also didn't help, the program was still growing in memory use (a
lot slower though but I don't call that a solution)

So if you have any more ideas let me know. I'll keep on trying

Kind regards,

Tim
