Re: Cannot start slave on IBM i due to java.io.EOFException
Your help was most welcome. Thank you very much for that. Most likely I will contact IBM support, now. Maybe they can help. At least it seems that it is not directly a Jenkins problem. Again, thank you. Thomas. -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.

Hi all,
I am new to Jenkins and I am lost. The problem is that I cannot start a

me.
