    My patch has suddenly developed a crashing habit. It seems to involve Java, but I didn't change the *only* mxj object used by the patch, and it's extremely simple -- it just takes 10 (index, freq) pairs from Jehan's pitch~ object, and converts them to multislider indices for a filter. I see "Low Memory Detector" in the crash log below, but it's only reading 20 atoms... Does anyone see from this what could be going on? Are there any simple cures (keeping in mind that this crashing started without any change to the mxj code, or to the process that initiates it).
    thanks in advance.

      okay, so maybe java isn't involved(?) I unhooked the mxj object and it still crashes. It seems to involve pattrstorage... not sure what's up, but I'll see if I can find it. Here's the crashed thread, in case it's obvious to anyone else.

      okay, got it. (just so nobody tries to figure it out) I had a pattr registered in two pattrstorage objects -- one was trying to linear interpolate and the other exp, on the same value. Not easy to do! ;-)
