eth0: memory squeeze, deferring packet.
I am seeing this message on the console screen of a virtual RHEL 4 server. The only references I can find on this date back to 2001 with a 2.4 kernel. I am running 2.6.9-42.ELsmp #1 SMP Wed Jul 12 23:27:17 EDT 2006 i686 athlon i386 GNU/Linux. This virtual server is running on a VMWARE ESX 3 server which has amd opteron processors in it.
It has 10 gigs of memory assigned to it and 2 gigs of swap. It also is running Websphere 6.0.
Has anyone seen this in the past or recently and do you know what it means. I believe is is causing the server to freeze and perform poorly.
