Hi,

Debugging a lot of code and need to log information instead of tracing the code.
Ran into a problem where not all my log are output into the /var/log/system.log .
We probably output too much for the IOLog pool to keep up.

This is a well known problem. I have run into this so many times that my blood pressure is now critical (from screaming and cursing at the machine). :) Apparently kernel logging is throttled for a reason. All I have ever heard from Apple is that it is throttled for a "very good reason" but no one ever says what that reason is.

It's almost impossible to track down problems with printf in the kernel because logs are lost so many times. The only way to reliably track problems is to get into the debugger, but then if you are debugging network communications, you have just stopped the kernel and the other end resends a bunch of packets and finally closes the connection.

Any way we could increase the IOLog pool or else?

Any other way we could manage to do this maybe?

I'm almost to the point of breaking down and writing a custom log pool for my own use. I don't know what else to do.
