saveDraftContest failing

[jmgasper]

I've been seeing this error more and more when launching challenges. Now I see it every time. The challenge still seems to launch, but there's a long delay and the error shows up.

[skyhit]

@jmgasper ok, will investigate into

[ajefts]

@skyhit I'm seeing this as well now. Can we put some priority on this one? Anything I can check for in the logs?

One thing I do see in the logs repeatedly is this:

[deedee]

@ajefts any other exception you've saw? Above exception has been handle and I don't think it was the caused.

[skyhit]

@deedee we used redis cache for local setup, but for dev and prod, we are still using jboss cache, will that be a problem?
is there any specific reason you created this SortedCacheAddress class?

[ajefts]

I see A LOT of this in the log:

[skyhit]

@jmgasper for that problem, is the challenge created? I am more considering that the backend service has some problem or network issue, since it is 504 status.

[jmgasper]

@skyhit - Yes, the challenge gets created, but the error displays after a noticeable amount of time.

[skyhit]

@jmgasper can not reproduce it.

@ajefts the class cast exception should be fixed. it will be available in next release. but it is not harmful, just logging

[jmgasper]

This has been happening to me about 50% of the time for the last 2-3 weeks.

[skyhit]

@jmgasper you used the Save Draft button or Submit button? I tried twice today, but no lucky

[jmgasper]

Submit. I rarely use the Save Draft button

[skyhit]

@jmgasper ok, I will try to reproduce.
