Hi, sorry for bad my English. I use google translate, sorry.
Carefully studied Wekaserver wiki. But I need more information.
I connect to my computer with the Internet Browser WekaServer following statements could not understand what it means.
"finished executing" is? What happens if I pressed the button located next toremove? Is the process remains in a half?
"The problem persisting Task" mean? bad or good?
"Purged task" mean? bad or good?
I chose the server is running on the cross-validation.
10 fold over the server before the end of a message he came to the screen.
Thank you in advance for your help.
Best wishes ...

Weka server was designed with unix-based systems in mind. Having said that, there is no reason why it shouldn't execute under Windows. It looks like Windows doesn't like the filenames that the server generates for storing temporary task files to. I quickly tested a single server under Windows and got the same persistence error that you did. The cross-validation completed successfully for me despite this error though. Are you using several slave servers (it is hard to tell from the screenshot of the console output)? I'm pretty sure that the filename issue is causing the "Can't find task" error and the failure to complete if slave servers are in use.
I've created a JIRA for this:
Thank you for your interest. I was fourteen on the Windows HPC Server 2008 computer (14 PC) trying to achieve by using the analysis. I have tried to analyze approximately 1.3 GB of data. I committed an error weka file server immediately sends the requesting computer. However, the requesting computer is still stage of 5 fold. The data is not sent by the server needs to fold before the end of the process. I was able to run on Windows HPC Server 2008. For parallel operation plug-before you tried weka-3-2-3. However, I gave up due to memory overflow. I tried to use your wekaServer program. I would request your help. (I sent pictures, but a large forum to be downsized.)
With my best regards.

There is not much I can do at the moment to help I'm afraid until I get some time to look into a fix for this bug. You can watch the JIRA so that you'll know when work has been done on this issue.
Hi Mark, thank you so much.
I'll become a follower of JIRA.

I wish you ease your work.
I've just released a new version of the wekaServer package (1.0.1) that fixes this issue.
