What is wrong with meleerumble?

That's because nobody is running a client for it. You're welcome to run it yourself, unfortunately I had to stop the client I was running when I moved out of my old lab.

I find it impossible to run a client for meleerumble, robocode just crushes on attempt to submit results. I have no such problem for roborumble, which continues to happily accept my CPU cycles :)

But someting is broken in meleerumble robocode. Here is the relevant part of the console log for ./meleerumble.sh v1.8.2.0 run

I just tried a client and it is working fine, so it seems like a problem with your install. Delete the /robocode/roborumble/files and /robocode/roborumble/temp directories and try again.

Thanks Skilgannon. Above recipe fixed the issue.

But I find it strange, I am quite sure that I was trying to run it from the fresh install.

There was an entry in meleerumble without link, Skilgannon repaired that. But to be sure that no old pieces are left behind, cleaning those directories is good practice.

Something is wrong with meleerumble. My client fails with

On top of it the last upload was 11 hours ago and it was from me, but I think it start to misbehave by this time already.

I think it's your client again, same fix procedure as last time. You aren't running two clients out of the same folder, are you? It can corrupt the results file, which causes the client to crash.

I am quite convinced that it is on my side, but I was suspecting that others had the same problem, due to lack of uploads.

Same procedure did not fix it, but today I started it again after 8 hours and it works now.

I do run roborumble and meleerumble in the same folder, strangely roborumble is stable as a rock, while meleerumble gives me hick ups. Do you suspect some race condition and advise to use separate folders?

Never mind, looks like it works now.
