I get a Panic whenever I run Mail on OSX whilst running Parallel - it seems like checking mail, or doing other network-intensive things, caused a kernel panic in OSX. Anyone else getting this a lot? imac Core Duo 20", 2GB Ram, 256mb Video Card

After another crash i decided to let PW to finish windows update first, but it crashed with the same IONetwork kernel panic right after i started installing SP2 thanks i

I've caused it to happen when the Windows side is just idling, but I've just booted Mail under OSX, or opened Safari, for example. Any developer care to comment?

The panic is sounds like a "free freeing mbuf". Is this right then we known about this, but else please send error reports to us (use reports@parallels.com for this)

I'm using Windows 2000 with SP4, via ethernet, on an iMac 2.0Ghz with 256mb vram and 2GB ram.

Will I have less problems if I use the airport for networking instead of ethernet? I can use either at this location. Thanks for the response, and good luck with the fix!

By the way, tell me how to check what caused the panic and I'll do so - is there a log I can check or something?

OS X 10.4.6, Build 8l1119

Are there any other issues that cause kernel panics I can try to avoid, aside from network matters?

And is there any reason why using airport should avoid kernel panics - I have to say the constant panics are driving me nuts and I don't want to crash my machine again :rolleyes:

That's my panic. Windows XP SP2 guest, OS X 10.4.6 with Boot Camp installed, MacBook Pro 2 GHz/1 GB/100 GB disk, Ethernet. (My Airport isn't reliable: for some reason, it keeps dropping the connection with my home access point - but no others.)

I'll try the next release. Right now, I'm using Disk Utility to repair my boot volume after the last panic.

I thought airport was not supported, but only wired ethernet?

If you click on Network Adapter on the properties page (the VM must be powered off to change this), you can select en1 instead of en0. This will switch to your Airport adapter. I've made the switch on my MacBook Pro, and am reinstalling XP on it now. I'm not going to be able to do much with it this way due to Airport problems, but at least I can get the reinstall out of the way.

snak-pak Junior Member Join: Apr 2006 Posts: 24	I have experienced a kernel panic as well. Sent the report to Apple, but I didn't save it. Next time it happens I'll forward it to you guys. Here are the details of what was happening: Was inside Windows 2000 VM trying to use the network... realized my ethernet wasn't plugged in. So I plugged it in, opened a command prompt and did a "IPCONFIG /RENEW" and then blamo! big kernel panic. OS X was doing other network activity at the same time, but using the Airport card. The VM was configured to use only en0 Ethernet. It's possible Win2k was trying to get a DHCP address already when I manually issued the command. But with a kernel panic it's a hard reset and quite nasty, since we lose all data on open documents. Not nice for a userland application to cause a kernel panic... :-) Details: MacBook Pro with Parallels beta for OS X; Windows 2000 SP4 with all updates.

It is supported, but you have to change the interface from en0 to en1 before you start the VM. Can't do it while the VM is running. You can also use Airport for OS X and wired Ethernet with VM like I was doing, but I did get one kernel panic as mentioned in the previous post.
