Parallels Mac causing crashes?

[Casemon]

Hi everyone, love Parallels, it is so wonderful. What a brave new world we live in! (And 3.0 sounds too good to be true, thought it isn't!)

However a number of mac users are finding Airport stops working after a time and sometimes causes a kernel panic! In either case, only rebooting seems to resolve it for a time.

What does this have to do with Parallels? After much trial and error, we seemed to have narrowed it down to the Parallels networking subsystem causing the errors; seems Parallels is the common denominator in all cases.

The behavior is usually preceded by the following console log errors;

... kernel[0]: ath_rx_proc: no mbuf!
... kernel[0]: ath_rxbuf_init: no mbuf/cluster

The main discussion on this at Apple is here:

Anyone at Parallels care to look into this? It's frustrating having such a great computer, then have it crippled by otherwise awesome software.

Thanks for taking a look at this!

I'm having the same problem

I'm having the same problems, but I don't get the advanced warning in the console you refer to. It's happened about 6 times in the last few months; and only happens when I'm using 802.11.

I'm not convinced it is Parallels, but I can't remove parallels to test without impacting my usage a lot.

Here's the panic log:
