We have a LB called sw002 that hosts muliple VIPs for muliple enviroments for multiple LB systems. One of the systems (ux118) in a dual LB enviroment, it is having issues connecting to LB IP as well as causing issues for anyone that gets put on that system from the LB. It took me a bit of time to get where I am. Sometimes I can login to the LB from ux118, until it times out. I am able to login to the LB w/o an issue from the sister system ux119 w/o an issue. If I ping the LB from both ux118 and ux119, ux118 will drop a good portion of the packets. I have no issues connecting from my local machine to ux118 or accessing the applications directly from ux118. The issue seems to be only between ux118 and sw002. I am wondering if it is something with the routing tables. There have been no recent chnages that I know of on the server and it has an uptime of almost 2 years.

Systems use RHEL 5.4
Dual IP (internal and external)
LB and Servers are in the same subnet

I am not a network guy and I would apperciate any help.

Kind Regards,

Hostage

I do see a new interface in ifconfig that I have never seen before: virbr0

Both ux118 and ux119 are physical boxes.
