Yesterday I noticed something weird with one of my mail servers (FreeBSD 7.2), which is located far away from me. At first I thought it was my mail client that was misbehaving since a couple of mails that I retrieved from the server looked...odd. Characters were missing, and the mail headers were sometimes (perhaps 1 out of 100 mails) sort of scrambled.

This server isn't doing anything really useful, except handling a few mails every day. No load at all and it has been running for a few months without any problems.


Anyway, after some time I realized that Thunderbird probably wasn't the problem. I discovered that ssh connections suddenly dropped (seems random) when I was connected to the server. Often with messages like:

Received disconnect from x.x.x.x: 2: Bad packet length 3365265859.

I tried to ping it and I constantly got 5-15% packet loss. The same symptoms are there if I connect to it from other places, so my home connection isn't the problem. I get 0 packet loss if I ping the gateway which the server is behind from my home connection.

Anyway, while I was connected to the machine (and scratching my head) I did a csup from the server to fetch ports and other stuff, but that failed every time, with different messages:

1st try:

 Edit ports/Mk/bsd.port.mk
  Add delta 1.625 2009.08.03.15.36.58 miwi
 Edit ports/UPDATING

3rd try:

Edit ports/devel/p5-threads-shared/distinfo
  Add delta 1.4 2009.07.22.17.25.14 pgollucci
 Edit ports/devel/p5-usb/pkg-plist
  Add delta 1.3 2009.07.30.23.04.41 pgollucci
csup: inflate: invalid distance too far back

Ok.  So something is messed up.

Checked my other server (located at the same place) to see if there were any problems (it is running VMware ESXI with 4 virtual machines, all running FreeBSD 7.2.), but all of the virtual hosts were fine. No packet loss, no ssh problems, no nothing. This server is connected to the same switch and behind the same gateway. So are also a bunch of Windows servers. None of them have any problems.

Checked the logs on my mail server to see if there were anything weird...and the logs were filled with this:

arp: x.x.x.x moved from 00:16:c7:24:69:ae to 00:16:cf:24:69:ae on bge0
arp: x.x.x.x moved from 00:16:cf:24:69:ae to 00:16:c7:24:69:ae on bge0

arp: x.x.x.x moved from 00:16:cf:24:69:ae to 00:16:c7:24:69:ae on bge0

x.x.x.x is my gateway which all my servers are behind. These messages started yesterday, about the same time that the problems appeared.

Any ideas? :-)
