Interesting, the pcap that was posted previously showed some odd errors
around udp checksums, some showed valid, some showed invalid. With
modern NICs it's not uncommon to see them all invalid due to checksum
offloading, but the mix of valid and invalid was odd.

I am running a demo of the Canit anti-spam software from Roaring Penguin
Software as an appliance (ISO) inside of Virtual Box for OSX. I was getting a
lot of these errors in the system logs:
6/26/13 11:38:37 PM kernel in_delayed_cksum_offset: ip_len 48640 (190)
doesn't match actual length 204
Shutting down Virtual Box stops the erros. So, until I figure out why that is
happening, I'll just let everything fail over to my secondary MX spam solution.
Very interesting. Now will have to do some research on the error as it
pertains to Virtual Box.

Yes, seems fine now. Can you share more information about what it was you
turned off? Sounds odd, but the results speak for themselves.

Sure could use some direction about where to start looking. I "thought" I had
everything working for the last few years, but now I'm beginning to question how long
I've had a problem.
The setup is OSX running BIND 9.9.3-P1 on a static IP, no firewall, no router,
just straight to the internet. I am also serving Apache and ProFTP on the same
box.
As a thought, I have had some strange errors in the console log, I think they
are coming from a spam solution I am running. I'm shutting it down
temporarily. Wonder if it could be corrupting the network. @Doug, could you
try your test again now, now that I've shut off the potentially offending
program?
