#2: Veeam ONE Reporting Service fails to start after the upgrade
Symptoms: During the upgrade, the "Failed to install extension modules" error appears. After the upgrade, Veeam ONE Reporting Service does not start.

Symptoms: If lightweight pooling is enabled on the underlying SQL server, the following error appears in the upgrade log.

Code: Select all

2021-00-00 00:00:00.0000 [ERR] 0x0670 -  9t -  1c PackInstaller -   -   -   -   -   -   - : ResourcePack installation failed
   System.Data.SqlClient.SqlException: Common language runtime (CLR) execution is not supported under lightweight pooling. Disable one of two options: "clr enabled" or "lightweight pooling".
After the upgrade, Veeam ONE Reporting Service does not start.
Cause: Unable to upgrade the report packages because enabled lightweight pooling does not allow using CLR types. Issue ID 301085.
Status: The current workaround is to disable the lightweight pooling on the SQL server. We are planning to address this issue in the next Veeam ONE version.

Cause: Syntax issue in the verbose-level logging of the communication with an SMTP server. Issue ID 303163.
Status: Please, contact our customer support for applying a hotfix.

#6: High CPU usage on Veeam ONE server after the upgrade
Symptoms: Veeam ONE server has started consuming way more CPU after the upgrade.
Cause: Most of the opened cases we've seen had different nature. Some of them have been related to a lack of CPU resources, some to improperly configured Veeam ONE Agent. We are still investigating a few of the cases.
Status: Please, contact our customer support to provide us with additional information.
