[Bioclusters] LSF 4.2 w/ Redhat 7.2 (2.4.X kernel with glibc2.2) install problem

[Chris Dagdigian]

Kristian,

Every LSF-based system I've had a chance to work on has had a similar 
architecture to what you describe (master node with multiple NICs 
multihomed to public/private networks etc..)

I've seen what you have described before but am fuzzy on what we did to 
get around the issue (hey its morning here). LSF is certainly sensitive 
to the order in which machines are listed in hostfiles so you may gain 
something by swaping entries around. I believe also that LSF can make 
use of a custom hosts file that you can drop into the local 
configuration directory...you may be able to create this file and list 
only the address of the interface you want the daemons to bind to.

Since I'm working now on a similar system I'll drop you an email 
off-list if I see the same issues. I already have one bug report to 
submit to platform with respect to the installer script.
