DVDpedia 5.0.2 apparently has some issues with memory management. I had just launched the program and was manually adding disc details when DVDpedia started beachballing.

It seems it went into a vicious cycle where it would rapidly allocate and release large amounts of memory; then, during the last cycle the process size will grow up to 2.6 gigabytes and then the process hangs.

I have seen this kind of behavior also with Bookpedia 5.

Some observations:

OK, I was able to narrow this problem to iSight window. Whenever I activate iSight, the process memory consumption explodes.

Initially, when started, DVDpedia takes approx. 30 MB of memory. After activating iSight the memory allocation grows to 1023 MB in one minute and to 2.02 GB during the next one minute. After reaching 2.6 gigabytes, the process hangs completely.

Thank you for all the details I see it in the logs as being something to do with the display of the image in the preview window, but haven't been able to repeat it. I'll keep testing and let you know if I can track anything down. What version of OS X are you running?

Posted: **Sun Feb 26, 2012 8:52 am**

Thank you for all the details. I updated DVDpedia to send more explicits instructions to the garbage collector. The garbage collector should normally kick in by default but in some cases it was growing past the threshold. Please try out the DVDpedia beta 23 and let me know if you still see the same issue. Bookpedia beta 19 is also updated if you would like to test that one out.

Posted: **Sun Feb 26, 2012 11:37 am**

Well, now the problem seems to be solved in beta versions. For what it's worth, I'm using OS X 10.7.3

Thank you.
