After creating the interfaces with ifconfig and setting it up so that traffic is hitting the carp IP the machines both just mysteriously freeze where they are 100% unresponsive. The machines are both Dell PowerEdge servers. One is a 2650, and one is a older 2500. The both are using Intel(R) PRO/1000 Gigabit Ethernet adapters (the em driver) The both have RAID controllers in them using the aac driver and mirrored system disk pairs. >How-To-Repeat: Just simply create the carp interfaces (does not matter if both machines are up or not) and pass traffic to the IP they are set to. Any sort of larger volume traffic causes the machine to instantly lock. >Fix: I have not been able to find any workaround to this problem. >Release-Note: >Audit-Trail: Responsible-Changed-From-To: freebsd-i386->freebsd-net Responsible-Changed-By: linimon Responsible-Changed-When: Mon Apr 6 06:24:37 UTC 2009 Responsible-Changed-Why: This does not sound i386-specific. http://www.freebsd.org/cgi/query-pr.cgi?pr=133218 From: "Philip Drapeau" To: , Cc: Subject: Re: kern/133218: [carp] [hang] use of carp(4) causes system to freeze Date: Sun, 3 May 2009 14:21:40 -0600 This is a multipart message in MIME format. ------=_NextPart_000_0001_01C9CBFA.7A4FEA50 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Good Afternoon, I have noted this bug has been sitting here in the open state for quite some time without any response.
