Defect.

This issue is resolved in 14.3.2 & later versions. Go to the Download Center and upgrade.

The Enterprise Vault (EV) OST Streamer component may crash while reading or writing data on secondary S3-compatible storage by many concurrent threads. This can cause an interruption in service until the storage service is restarted. There can be different errors in the EV event log depending on which components are active at the time. If this issue is encountered, the Windows application log will show one or more Event ID 1000 from Windows Error Reporting involving the DLLHost.exe process.
