Hey 87racer… it's probably better to link directly to the post.

It seems to be your blog - so that way, anyone trying to find a solution for their audio problems in Airfoil will be sent directly to the instructions on how to fix it, rather than seeing your latest blog post and having to search for the answers they need.

Direct link is here:

Airfoil is working fine for me, but it crashes after about 10 minutes. Anyone else having this problem?

@Fish On my Mac it's crashing if the memory is full, an it uses lots of memory.

@Felix Ah, yes. That seems to be the problem. If I monitor Airfoil in Activity Monitor Airfoil starts with a memory usage of about 200 MB and then it is increasing rapidly. After about 5 minutes it's up at 1500 MB memory usage and crashes. So there's some kind of memory leak in Airfoil in OSX 10.7. Is there a temporary way around this that you know of?

Same thing for me. It actually goes up to using over 2200 Mb of memory before crashing. Any ideas for a fix anyone?

@Gravol. Yes, on second look, mine will also go well above 2 GB. I have notified Rogue Amoeba Software and they are working on it.

Any updates about Airfoil's status? The latest version still crashes after a few minutes, in my experience.

@Artemio Gonzalez I have been testing a new preview of Airfoil which is fully functional. They'll proboably release it when Lion gets out.
