warning messages in orbeon logs

We are seeing WARN messages in orbeon logs a lot. Can anyone tell what this mean and does it have any impact to performance?

2010-05-25 11:32:39,308 WARN  XFormsServer  -   xxforms:instance() - instance not found {instance id: "fr-uuid"}
2010-05-25 11:32:39,309 WARN  XFormsServer  -   xxforms:instance() - instance not found {instance id: "fr-save-locally-file-name"}
....

2010-05-25 13:34:12,334 WARN  XFormsServer  - exception copying stream {throwable: "java.io.PrintWriter@72eae5"}

Hithesh,

Most likely this is nothing to be worried about, but I'd like to
double check that. How can I reproduce this? When are you getting
those warning messages?

We are seeing following warning messages almost whenever you open form(using form runner) to add new,edit, click on any form field.

2010-05-26 11:22:01,085 INFO  ProcessorService  - /xforms-server - Received request
2010-05-26 11:22:01,409 WARN  XFormsServer  -   xxforms:instance() - instance not found {instance id: "fr-uuid"}
2010-05-26 11:22:01,409 WARN  XFormsServer  -   xxforms:instance() - instance not found {instance id: "fr-save-locally-file-name"}


We are getting stream exception warning; I guess when session is created when form is opened, But Its happening on only on server and not other

2010-05-26 08:01:52,983 INFO  OrbeonSessionListener  - Session Listener - Session created.

Hithesh,

I wouldn't worry about those "instance not found" warnings in Form
Runner. Most likely we need to do some cleanup there, but it shouldn't
really cause any hard problem. For now, I created this bug to track
this:

http://forge.ow2.org/tracker/index.php?func=detail&aid=315048&group_id=168&atid=350207

As far as the "exception copying stream", do you have the full
exception (or at least the first 20 lines or so)? Do end users see an
error in the browser when this happens, or does it seem that this
exception is without consequence?
