After upgrading the NetWorker server (Linux, Windows, or NVE) to version 19.12 or later, HP-UX Client backups fail with an authentication error while attempting to obtain RPCSEC_GSS credentials. This issue is observed in NetWorker versions 19.11.0.6 (partially affected) and later and is independent of the HP-UX Client version, affecting both upgraded and non-upgraded HP-UX clients. Additionally, the issue can be encountered when attempting to add or register an HP-UX client on an upgraded NetWorker server, preventing successful client configuration and communication.

Unable to launch NetWorker Management Console (NMC) due to a malformed gconsole.jnlp file.

During a Bare Metal Recovery (BMR) performed through NetWorker, unable to load any operating system drivers, such as Network or Disk Drivers.

The nsrazure_recover command is used to recover an Azure Virtual Machine (VM) snapshot that was backed up using NetWorker. The command fails almost immediately, reporting "Target VM must already exist for a single disk recovery."

OpenSSL version 1.0.2 detected on vProxy appliance

NMC authentication is configured to use Active Directory credentials. The authc_mgmt query operation correctly returns only valid Distinguished Names (DNs) and does not return usernames.

When configuring NDMP backup for PowerScale (Isilon), there is a configuration setting called "Data Management Application (DMA) vendor." For Avamar to successfully backup from PowerScale, it must set to "generic" vendor per the "NDMP User Guide".

Served XML license not working with NetWorker Virtual Edition (NVE) due to entfirewall blocking port 31216

Starting NW 19.13.0.3, save set with DD retention lock enabled is allowed to change ssretent and ssbrowse. It mistakenly allows save set retention time shorter than ddrltime lock time

NetWorker Management Console (NMC) installation fails on a Windows host with error: "Unable to verify Authentication Server's hostname or port."

NetWorker for Windows issue: double clicking "Server db Backup" action in the Workflow Server Backup results in a popup error -1>=2 due to Java (Java) ArrayIndexOutOfBoundsException.

When installing the NetWorker Management Console (NMC) or NetWorker Web User Interface (NWUI) on a Windows host, it fails to connect to the NetWorker authentication server. The NMC/NWUI server is separate from the NetWorker server. Name resolution and port connection tests are successful. The problem occurs when TLS 1.1 and 1.2 are disabled on the standalone NMC server.

The NetWorker Management Console (NMC) upgrade or install fails on a Windows host. The installation immediately returns "Unable to verify Authentication Server's Hostname and/or port."

The NetWorker Management Console (NMC) server deploys with a self-signed certificate. The self-signed certificate was replaced with a CA signed server certificate. After replacing the certificate on a Windows NMC server, the server's GSTD service fails to start, reporting "gstd NSR warning Error getting certificate and private key for SSL"

A File Level Recovery (FLR) is performed for a Windows Virtual Machine (VM) using the NetWorker VMware Protection (NVP) vProxy appliance. The FLR fails with the message "Some objects, or security properties could not be recovered." For some files, these same files cannot be copied manually from the FLR mountpoint. The source and target VM are different VMs. The VM selected for restore is configured with the Windows File Server Data Deduplication feature enabled.

NetWorker VMware Protection (NVP) Virtual Machine (VM) backups are being performed. During backups, unallocated disk space is being calculated as changed data and is written to Data Domain, resulting in slower than expected backup performance.

The NetWorker VMware Protection (NVP) vProxy appliance is configured to back up a SQL Server 2022 Virtual Machine (VM) using MSVMAPPAGENT. The backup fails with "'Unable to log in to SQL Server instance. Error Code = 1359.'"

After performing a NetWorker disaster recovery (nsrdr) procedure, Oracle Recovery Manager (RMAN) backups fail with a lockbox error ("Failed to open lockbox"), while NetWorker client file‑system backups continue to complete successfully. The nsrdr process does not fully restore the Oracle client lockbox data, which prevents the NetWorker server from retrieving the Oracle credentials required for RMAN backups. Deleting and re‑creating the affected client lockbox resolves the issue.

The NetWorker Web User Interface (NWUI) Dashboard tab displays the error "Failed to fetch latest counts for Dashboard" and does not show details for Policies, Workflows, and Actions. The error occurs because the NetWorker Runtime Environment (NRE) keystore is either missing the emcnwuimonitoring certificate or contains a certificate whose signature does not match the one used by the NWUI monitoring service. Importing the correct certificate into the NRE keystore and restarting the NetWorker service resolves the issue.

Virtual machine (VM) backups performed with the NetWorker VMware Protection (NVP) vProxy appliance fail intermittently with a "Resource not found" error (code ‑404) because the vProxy ages out a completed backup session before the NetWorker server retrieves the final status. High network latency between the NetWorker storage node and the Data Domain causes the NetWorker server to delay its status‑polling requests, which allows the vProxy session to expire. Reducing the storage‑node‑to‑Data‑Domain latency to below 50 ms resolves the issue.

The NetWorker server nsrmmdbd is being killed by the operating systems "Out of Memory" (OOM) monitor.

NMC was generating the following alert: Cannot write to /Database/Database/97/08/50dea767-00000006-2b43c6c3-6a43c6c3-edd60c00-c89dd629 - errno Invalid argument
