[NOVA] Deadlock 2/16/09

Hi folks,

The server is deadlocked.

A deadlock means to you that Status shows UP but you cannot login. Think of it like a frozen PC. It needs to be reset.

Our guys that are responsible for resetting the server and handling the crash logs are in Europe. When they wake up, they'll likely reset the server and address the crash. Please try to be patient, we're in development, and NOVA is a test center.

Until then. hang in there! Come hang out in IRC or Listen to EMURadio.

A common question.
What is deadlock?

Quote:

In computer science, deadlock refers to a specific condition when two or more processes are each waiting for each other to release a resource, or more than two processes are waiting for resources in a circular chain (see Necessary conditions). Deadlock is a common problem in multiprocessing where many processes share a specific type of mutually exclusive resource known as a software, or soft, lock. Computers intended for the time-sharing and/or real-time markets are often equipped with a hardware lock (or hard lock) which guarantees exclusive access to processes, forcing serialization. Deadlocks are particularly troubling because there is no general solution to avoid (soft) deadlocks.

This situation may be likened to two people who are drawing diagrams, with only one pencil and one ruler between them. If one person takes the pencil and the other takes the ruler, a deadlock occurs when the person with the pencil needs the ruler and the person with the ruler needs the pencil, before he can give up the ruler. Both requests can't be satisfied, so a deadlock occurs.

The telecommunications description of deadlock is a little stronger: deadlock occurs when none of the processes meet the condition to move to another state (as described in the process's finite state machine) and all the communication channels are empty. The second condition is often left out on other systems but is important in the telecommunication context.

Thanks to Wiki.

Thank you, have not encountered this before and was checking everything to do with the net client side here.

Thanks Lubbe. I should have linked the definition for those interested.

Thanks much for the update, and thanks once again for all the work that everyone has put into this project. It's a really nice break from the corporate culture that tends to make a mess of other MMOs.

I'm a professor at a College of Social Sciences, and when I'm taking a break from preparing lectures, grading papers etc., I like to pop in and test things out. It's a privilege to be a part of the process.
