Hello,

We need more information to address your issue.

Could you please clarify in which Talend version/edition you are? Would you mind sharing the following files?

- tomcat logs (preferably archive of whole /tomcat/logs/ directory).

- TAC debug logs (we need the whole tac logs directory, not just technical.log).

Best regards

Sabrina
