The WriteInstalledFileEvidenceAttribute inventory import writer step may run for a long time, and even eventually terminate with a timeout error when using the FlexNet Manager Suite 2022 R2 release.
This issue is caused by a SQL database query that can perform poorly under certain conditions.
Logging like as the following will be produced by the import process when this step fails with a timeout error:
2022-11-29 06:51:08,931 [INFO ] WriteInstalledFileEvidenceAttribute
2022-11-29 14:51:12,135 [INFO ] Failed to execute Writer 'WriteInstalledFileEvidenceAttribute' from file C:\ProgramData\Flexera Software\Compliance\ImportProcedures\Inventory\\Writer\FileEvidence.xml, at step line 1
Error: Execution Timeout Expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
