I just thought I would relay some info I got from an PSS Escalation Team member regarding the Broadcom/Chimney issue. He gives the following more in-depth explanation:
"...We have experienced in some cases where hang was caused by the Broadcom NIC driver. This driver was making a request for contiguous memory and the system was flushing pages attempting to make memory available to satisfy the request. While the system is attempting to satisfy the request, all page fault requests for memory are suspended. So this would cause a performance hit. The driver may have been making a high number of requests for contiguous memory." Hope that helps... jlc ~ Upgrade to Next Generation Antispam/Antivirus with Ninja! ~ ~ <http://www.sunbelt-software.com/SunbeltMessagingNinja.cfm> ~
