XPages http crash

I have a complex XPages application that uses various features and components such as:

- extension library and SCDX, Scope variables.

Sometimes the server crashes. The log shows a generic java.lang.NullPointerException.

The reason for the crash is not attributable to a particular actions.

It's necessary to restart the http

Do you have any suggestions for improving diagnostics.

Re: XPages http crash

To troubleshoot this, we'd need way more information than what you've provided. Can you pinpoint the cause of the crash? You might want to consider opening a support ticket w/ IBM.

Re: XPages http crash

I tried to understand the point but is not possible.

This happens both when I have a XPages connected to different data sources (view or document).

It seemed to me could be a problem of session, but it also happens when I'm working on.

I enabled the JVM logs for more information but the result is not always clear.

IBM is a possible soluzioine but in future I'd like to understand what makes the server crash.
