Problems with event management

We have ran into a strange problem with the event management. It stops working a few minutes after an application restart.

Repro:

  1. Restart application on both servers
  2. Update page on server A
  3. View page on server B
  4. Verify that the page is updated on server B
  5. Wait a few minutes
  6. Repeat step 2-4

Expected

I should se the updated page on server B in step 6.

Actual

I cannot see the updates to the page on server B

Things we have considered and checked:

  1. The UDP configuration seems correct as documentations states it.
  2. We have two applications on the same server. We have tried using different udp ports
  3. We have regenerated machine keys

As the documentation says "Be sure to use unique port numbers if you have multiple installations on the same network.". What are considered as the same network?

Help needed! :)

What kind of UDP are you using?

If you use UDP broadcasting it will be sent to all computers on the same network/subnet.

The documentation just states that having a production and stage environment in the same broadcasting segment using the same port is a bad idea. surprised

Apperently, multicast streams needs an igmp snooping querier per virtual lan in order for it to work.
