Looking at our list of network events going by in Splunk, the switch interface connected to the above mentioned host is flapping continuously.  

This log message is going by at a steady rate:
Sep 30 01:07:09 eswd[1012]: %-ESWD_STP_STATE_CHANGE_INFO: STP state for interface ge-1/0/38.0 context id 0 changed from LEARNING to FORWARDING

So...> show ethernet-switching table | match 38
  community         c8:2a:14:20:98:4b Learn          0 ge-1/0/38.0

then:> show arp no-resolve | match c8:2a:14:20:98:4b
c8:2a:14:20:98:4b   reth0.20             none

host domain name pointer

Inventory just says this is allocated to "community" -- anyone know how we find out more?

[08:58:50]  <dcurado>	OK, I'll start digging there.  Thank you for the pointer!

From Kairo:

Hi Dave,

Callek and ewong (that's also their IRC nicks) are the people dealing with SeaMonkey infrastructure nowadays. I know there are issues with the minis (I think the project only has two left and that's really tight), but not more than that.

09:57:04]  <ewong>	dcurado: re: sea-mini-osx64-1  issue..
[09:57:07]  <dcurado>	yes
[09:57:10]  <ewong>	dcurado: can you clarify what you mean?
[09:57:16]  <dcurado>	yes
[09:57:37]  <dcurado>	the switch port that the mini is connected to is going up and down at a constant rate
[09:57:46]  <dcurado>	looks clearly broken to me
[09:58:08]  <dcurado>	However, I don't know if that's the mini, or the cable connecting it to the switch or what
[09:58:15]  <ewong>	dcurado: so is the switch busted or is the mini causing the switch busted?
[09:58:29] 	jib ( left IRC. (Connection closed)
[09:58:42]  <dcurado>	All the other ports on the switch appear fine, so I would *guess* the mini or the cable it uses to connect to the switch
[09:58:49]  <dcurado>	But I could be wrong.  It could be the switch port as well.
[09:58:51] 	jib ( joined the channel.
[09:59:07]  <dcurado>	I wanted to make sure that this server is actually doing something.
[09:59:17]  <ewong>	give me a sec.. lemme see if  can see what's going on with the mini..  
[09:59:26]  <dcurado>	Then, if so, ask if its OK if we dork with it to try to remedy the issue.
[09:59:28]  <dcurado>	OK, thanks!
[10:00:27]  <ewong>	dcurado: well, from what I see, it looks like it's building something..
[10:00:38]  <dcurado>	OK
[10:00:43]  <ewong>	dcurado: lemme check more
[10:00:50]  <dcurado>	Thanks again
[10:02:28]  <ewong>	dcurado: well so far, it looks ok.  
[10:02:38]  <ted>	catlee: log scraping is full of exciting ways to break shit
[10:02:44]  <dcurado>	Hrm.  OK.  Thanks for checking.
[10:02:47] 	armenzg is now known as armenzg_brb
[10:02:58]  <ewong>	but since I'm also viewing it via ssh as well as the master.  I'm probably missing something
[10:03:14]  <dcurado>	I was trying to pull up the total number of times it has flapped in the past 24 hours, and it seems to have quieted down over night.
[10:03:16]  <ewong>	dcurado: would switching a cable help testing it?
[10:03:23] 	AutomatedTester|AFK is now known as AutomatedTester
[10:03:41]  <dcurado>	So maybe it was a temp issue... (although, I know that doesn't happen often)
[10:03:59] 	JoeS1 ( left IRC. (Client exited)
[10:04:07]  <dcurado>	For now, please ignore.  If it acts up again, I'll come back to you and we'll see if we can plan a time to test it, OK?
[10:04:18]  <ewong>	dcurado: well.. thanks for monitoring it..  if it does flap, please ping me or Callek
[10:04:30]  <dcurado>	Thank you very much for getting back to me on this.

This port is still flapping quite a bit, but pinging the host shows no loss in connectivity.
I suspect the ethernet hardware on the mac mini is failing, but resetting itself quickly so there are no
packets lost.  It's just a "best guess" as to what is causing this issue.

Van -- next time you are SCL3, can you check the cable that connects this mac mini?
Maybe it's loose and causing this issue.  Kind of a long shot, but would like to do
something about this.
