Can you provide some details about your exact issue with Job Server and TAC and what is your Big Data context?
At Talend, not everything is perfect, but we always do our best to support our customers and provide solutions or workarounds whenever possible.
Thanks for the details. It can be sometimes difficult to reproduce exactly a customer's issue. I'm sure that Talend Support tried his best to help, and possibly they ask for you to "play around" with the thread count in order to see if this sheds some light at the source of the issue.
I'm really sorry that we couldn't help you with this freezing job in TAC. However I can't see the Customer portal ticket around this issue. I'll take it offline with our Customer Care organization and will see how we can help further. I don't think the Talend Community can help in this issue, I'm afraid.
Thanks for your information. Could you please let us know your company name if you don't mind? We will appreciate it if you could post your log or error message on forum.
Many thanks for your time.
