Not all interfaces come up

[Carlos Infantes]

We had the same issue here, and after a lot of work we think that the 
problem is with the LAN driver. Pulse try to get up the interfaces more 
fast than the driver can handle and some IPs dont get up.

Our "solution" was install RedHat but over XenServer, the hypervisor 
handles the interfaces without problems.

This happens on a start, a restart, relocating to the backup pulse box, relocating back to the master pulse, etc. Following which the alias interfaces that don't come up need to be brought up manually before those balancers work.
