[zones-discuss] extensive packet loss when zones are booted

Alastair Neil Tue, 22 Aug 2006 05:59:06 -0700

Hi I have a Sunfire V440 with 2 processors and 10Gbytes of memory I have configured eight zones all using the second ce interface ce1. The port is connected to a nortel buisiness policy switch running at 100Mbs/full duplex. I am seeing unacceptible levels of packet loss to the systems. With all the zones booted and idle we get around 5-6% loss which can climb to 50-60% with activity. One of these zones will run apache2, the rest will be running tomcat.

I would appreciate any assitance as I am new to zones. Is this configuration excessive for the hardware?

Here is the output from ifconfig -a:
