Hello,
I can't reach the Report Problem dialog.
From the About page, I have oXygen XML Web Author Component en cours 25.0, build 2023021715/2023021310.

Another GRAVE exception is present in localhost.log file (and not in oxygen.log file) :

Hello,

We investigated the errors you reported and here is our conclusion:

You experience a case in which documents remain in memory after the HTTP session of the user expires. This causes them to be persisted to the Web Author disk after 12h (the duration of the HTTP session). This is a case that should not happen with default configuration.

The first error that you receive is benign. Its effect is that such old documents are not serialized to disk, but discarded permanently.

The second error you encounter has visible consequences - some HTTP responses return status code 500.
It happens when Web Author performs an unlock twice - which is not a problem in itself. When we reproduced it, its root cause was an exception that happens when a document is disposed you can look for
Code: Select all
```
RESTDocumentManager.disposeDocumentWithId
```
in the logs to confirm that your situation is similar.
Anyway, we implemented a fix in Web Author 25.1 to ignore this exception.

As a conclusion:

The second error is probably causing most of the problems and it will work better if you upgrade to Web Author 25.1.

There is probably another problem with your Web Author instance: a non-standard configuration of the HTTP session duration, or an error thrown by a plugin when the editor is closed. However, Web Author 25.1 is more robust to this kind of errors.

Best,
Cristian

Hi,

You're right. This second error causes visible consequences, many HTTP 500 and users can't work on document.
I confirm my situation is similar to the one you describe.
I see some errors on dispose when unlocking content.
Below an exemple :

We 'll try to upgrade to the last version.
But before, do you think it is a good idea to work on my lock handler and make sure no exception is thrown on unclok operation ?

Hello,
If you do not throw the Exception from your unlock method, I would expect that the problem will be fixed.
Best,
Cristian
