Hi,
my program on my spider is running without problems, but after about 10-15 minutes it freezes. It throws no obvious exception except of this debug print:

Is this a memory-problem?

with the memory on a Spider, it’s unlikely !

How did you prove it’s “frozen”? What does your app do and what stops?

Actually its just measuring Accelerometer & gyro values and showing them on the display. After some time the values stop updating on my display. It doesn’t store the values, in an array for example…

355 ms in gargabe collection is a lot of time.

have you tried to pause the program in the debugger and see what is happening?

Your question is missing one or more of these details:[ul]
The name of the product.
The code you’re trying to run.
Details on your setup.[/ul]

Your binary blob head is quite big. Serial related?
