com.danube.scrumworks.exception.ServerException: The server xxxxxx failed to respond

Edit Subject

Getting errors if there are a number of clicks in short succession.

Same error from multiple clients, cleared java caches, windows and linux clients. Clicking again commonly allows the action to proceed.

Access to scrum server is across a wan, latency between client and remote server is around 30ms.

Hi Mockodin,

Between this and previous cases it looks like you are having some serious connectivity issues between the client systems and the server.

If you log into the server that ScrumWorks is installed to, and start the desktop client up from there, do you see any of these same errors?

If so, then we will want to look at the server itself, and what could possibly be going wrong there. If not then the issue is going to come down to troubleshooting the connection.

I did have one case in the past with similar connection issues. We eventually resolved it by finding a faulty power supply. The problem in that case was that the power supply would stop functioning for just a second or two, causing all sorts of havoc, but was very difficult to discover.

This is a headless linux environment, access is ssh only. To logging in from the host is not an option.

The power supply is unlikely, given both modules would have to be in a similar state.

It does appear centric to the host however. Will update when I have more information.

Alright so it appears to be an issue with using xinetd for server side port redirection of 80 to 8080, while it worked it appeared to recreate the sessions quite frequently.

We have since changed the method to use an iptables redirection which is working fine.
