Known issues

Performance issues when using AlertStack

Enabling AlertStack may lead to performance degradation in certain environments.

Resolution or workaround: Disable AlertStack to restore expected performance.

If you have SendTrustedIssuerList enabled, the Configuration wizard may fail

SolarWinds internal certification authorities are not stored in the system trusted certificate stores. When SendTrustedIssuerList is enabled, the system only allows client certificates signed by trusted certification authorities, causing the SolarWinds client certificate to be rejected.

The Configuration wizard may fail with the following message.

Failed to setup RabbitMQ for SolarWinds Platform

Resolution or workaround: Follow the instructions in the "Failed to setup RabbitMQ for SolarWinds Platform" when SendTrustedIssuerList registry key is enabled article.

Network Atlas map errors when rendered from the Custom List of All Maps widget

When you upgrade to 2025.4 and open a Network Atlas map from the Custom List of All Maps widget, an unexpected error while generating the map occurs.

Resolution or workaround: Switch the application pool from 32- to 64-bit mode. See How to Switch IIS Application Pool Between 32-bit and 64-bit Mode.

Custom Cisco ACI alerts retriggering after upgrade

Cisco ACI monitoring has been migrated to a new technology. As a result, your custom alerts may retrigger after the upgrade and deprecated SWIS properties will no longer work as expected.

Resolution or workaround: Review your custom Cisco ACI alerts and replace deprecated properties with supported ones. See Deprecated wireless entities.

Invalid real-time data for interfaces

When you upgrade to 2025.4 RC1, real-time data polled for interfaces may be invalid.

Resolution or workaround: This will be addressed in a future release.

Performance impact on selected NetFlow resources

After upgrading to NTA 2025.4, you may experience reduced performance in the Endpoints, Receivers, and Transmitters resources.

Resolution or workaround: This will be addressed in a future release.
