Hil folks,
We have a primary server, on Linux. We also have 2 horizontal clusters for Mid-tier. Sometimes, the following situation occurs, even after a fresh services restart:
1. Open SAS VA page without problem:

2. But then, when I enter on Administration page, or any other, a 404 error page appears. The only solution, when it's happends, is stop the cluster server, keeping only primary server up.
