"Cannot forward after response has been committed" Error

[Vinicius Assef]

Hi there.

We're using DSpace 4.3 with JSPUI and I (the system administrator) am receiving some messages regarding an error when user tries to submit an item to the repository. It doesn't always throw this error and, AFAIK, the user doesn't see any error message, too. That's what's intriguing me.

Any advice about it is welcomed.

The message follows below (with anonymized data):

--- (start) -------------------------------------------------

Subject: DSpace internal error.
