Summary

On FlexNet Manager Suite systems where a large volume of unique filenames have been imported, the “WriteFileEvidence - Insert unmatched evidence” inventory writer step may fail due to the FileEvidenceFileID identity column in the FileEvidenceFile table in the compliance database growing too large and running out of available values.

Details

When this issue occurs, inventory imports are likely to fail with an error similar to the following:

2019-11-15 06:57:00,735 [INFO ] WriteFileEvidence - Insert unmatched evidence
2019-11-15 07:00:24,730 [INFO ] Failed to execute Writer 'WriteFileEvidence - Insert unmatched evidence' from file C:\ProgramData\Flexera Software\Compliance\ImportProcedures\Inventory\\Writer\FileEvidence.xml, at step line 108
Error: Arithmetic overflow error converting IDENTITY to data type int.
Arithmetic overflow occurred.

The following SQL query can be executed against the compliance database to identify the current identity value in the FileEvidenceFile table:

SELECT IDENT_CURRENT('dbo.FileEvidenceFile') AS CurrentIdentity

This issue is likely to occur if the value returned by this query is at or near 2,147,483,647 (being the maximum value that can be stored in a SQL Server INT value).

Mitigation

This issue may be mitigated by executing the following SQL query against the compliance database to reseed the FileEvidenceFile table to use negative identity values:

DBCC CHECKIDENT('dbo.FileEvidenceFile', RESEED, -2147483647)

Note that this mitigation can only be done once. If this mitigation has been previously applied and the database has continued to grow such that all negative identity values have been subsequently used then imports are likely to start to fail again.

Related issue

Also see the following issue, which can result in the same symptoms as this issue, but with a different root cause: "WriteFileEvidence - Insert unmatched evidence" import writer step may fail with error due to NewFileEvidence_MT.FileEvidenceID identity column value reaching limit of 2^31: "Arithmetic overflow error converting IDENTITY to data type int" (IOJ-2082391).

Fix status

This issue is still open but not currently scheduled to be addressed.
