Robert, thanks for the answer, it guided me to find the causer.

I identified in the application log that it is giving an Illegal web request error, from a SOAP class that exists in the namespace.
Probably someone is insistently calling this class externally in the wrong way, and IRIS is storing errors on every call. Is there a way for me to parameterize the namespace so that it doesn't store this error?

Thanks.

Tks man, it works too \o/

It works fine... Tks a lot.
