i'd like to find someone to help me debug a piece which i have just 

finished for a museum in paris. it needs to be running 12 hours a 

day for 6 months, and stability is important.

I've got the the piece working properly, but i seem to have an 

intermittent crashing problem which is both difficult to reproduce 

in short, max simply quits at random moments, which may be hours into 

it's running. i'm using open gl videoplanes, 2d and 3d text, and 

the aka.listen external, as well as jit.uldl to retrieve rss feeds.

so if anyone would like to help, i sure could use a second opinion 

and some suggestions. at this point, i have spent a good deal of 

time trying to track down any errors on my part.

below is the output from the console, max crash log, and the java 

thanks, and any help is much appreciated,
