Fixed customer issues

Case number	Description	Platform product
02096968	The Job Engine v3 health check now includes a timeout, preventing the service from hanging indefinitely.	Platform
01929418	WMI polling performance no longer intermittently fails with an `InvalidCastException`, which could result in deadlock errors and statistics not being updated.	Platform
N/A	Communication by the job engine is now more reliable, reducing polling disruptions caused by startup timeouts.	Platform
02088159, 02093677, 02094335, 02097091, 02104915	In the previous version, nodes that were `Up` but had persistent polling issues were identified with the message `Polling is failing`. However, this message did not always specify a reason for the failure (for example, when the error code was uncommon or unmapped). Each `Polling is failing` error message now includes information to help you determine why polling failed. Examples include: `SNMP polling is failing: 'Cannot retrieve the required OID on the target device. Verify that deviceID is accessible using the current configuration.'` `SNMP polling is failing: 'Unknown error: Check the PollingErrors table in the database or verify the polling credentials on the Edit Node Properties page.'`	Platform
02080562, 02109081	Processing firewall events no longer causes performance degradation and high CPU utilization.	NTA
02043500, 02061753, 02084215	Communication between the Certificate Management Client and the Certificate Management Service no longer fails, leading to issues with upgrades and the job engine.	Platform
02088982, 02094071, 02095672, 02095006, 02096433, 02099463, 02104914	When a node is polled via SNMP, polling no longer fails if the node does not support the OID for SysUpTime (1.3.6.1.2.1.1.3.0).	Platform
01167579, 01572999, 02017528	All dependencies on Visual Studio C++ have been removed, and no version of Visual Studio C++ is installed with SolarWinds Observability Self-Hosted.	Platform
02101384	Changing the width of a connecting line on a map no longer results in an error, and the Save button is enabled after the change.	Platform
02093343, 02093654, 02093962, 02093998, 02094734, 02095524, 02095753, 02096389, 02099214, 02099574, 02100789, 02100976, 02101562, 02101580, 02102512	When a high availability pool is enabled with a virtual host name, the pool no longer consumes a large number of UDP ports until it eventually runs out of ports.	Platform
02086086	When monitoring a computer running a Linux-based OS, an `ArgumentNullException` exception is no longer thrown if the cached memory or memory buffers volume is missing.	Platform
02104914	An issue with receiving a large number of results from polled devices, such as wireless access points, has been resolved.	Platform
02090203	When you attempt to edit a passive agent, the Manage Agents page opens and the agent can be successfully edited.	Platform
01822848	PCU (Power Control Unit) discovery now correctly deletes old discovered PCUs when auto-import is enabled, preventing duplicate PCU records and incorrect poller assignments on subsequent discovery runs.	Platform
N/A	Banners are now locked at the top of the page so they remain visible when you scroll down.	Platform
01794634, 02059681	Users with only the Allow Account to Unmanage Objects & Mute Alerts privilege can now view the Manage Entities page to unmanage objects or mute alerts in bulk.	Platform
N/A	Users with administrator privileges are now able to change the high availability (HA) server role when they edit an HA pool configuration. Previously, the role dropdown was unavailable for additional polling engines, preventing role changes to Standby.	Platform

Deprecation notice

The following platforms and features are still supported in the current release. However, they will be unsupported in a future release. Plan on upgrading deprecated platforms, and avoid using deprecated features.

SolarWinds Platform Agent support for Windows Server 2008 R2, Windows 7

Windows Server 2008 R2 and Windows 7 reached End of Life and are no longer supported by SolarWinds Platform Agents. To continue monitoring them, consider switching the polling method to remote monitoring with WMI.

SQL Server 2016

SQL Server 2016 is deprecated as of 2025.2. It is still available and supported in the current release, but will be removed in a future release. Consider using SQL Server 2022 or later.

Network Atlas

Network Atlas is deprecated as of Orion Platform 2020.2. It is still available and supported in the current release, but will be removed in a future release. Deprecation is an indication that you should avoid expanded use of this feature and formulate a plan to discontinue using the feature. SolarWinds recommends that you start using Intelligent Maps in the SolarWinds Platform Web Console to display maps of physical and logical relationships between entities monitored by the SolarWinds Platform products you have installed.

Starting with 2024.2, you can import Network Atlas maps to Intelligent Maps. See Import maps.
