Stability of Word generation on Words.NET component

Hello,

We use the Aspose.Words for .NET (version 16.11) for generating complex report through a windows service called from a web application. This worked quite well during all our development and our tests but now that the application is in production it seems that the report generation is not stable.
When there are more and more users generating reports, at a moment we receive the following errors (sorry for the not readable characters coming from aspose obfuscation):
System.NullReferenceException: Object reference not set to an instance of an object.

at Aspose.Words.Reporting.ReportingEngine.BuildReport(Document document, Object[] dataSources, String[] dataSourceNames)
After this, the report engine is totally down and cannot produce any more report and we need to restart the service to be able to produce new reports.

Does anyone already had this issue ?
How can we correct this ?

Best regards,

Eric
