Notes

  • This hotfix cannot be uninstalled! If you have any problems with Hotfix 6, contact SolarWinds Technical Support. Technical Support cannot remove this hotfix after it has been applied, however if you experience a problem, Support can work with you to resolve the issue.
  • This release includes the following LEM Manager and LEM Agent updates:
    • LEM Manager Hotfix 6
    • LEM Agent Hotfix 5
  • If you applied LEM Agent Hotfix 5 last release, you only need to install LEM Manager Hotfix 6. If you did not apply LEM Agent Hotfix 5 last release, apply LEM Agent Hotfix 5 and LEM Manager Hotfix 6 at the same time. 
  • This is a cumulative hotfix that includes fixes from Hotfix 1, Hotfix 2, Hotfix 3, Hotfix 4, and Hotfix 5.

Fixed Issues

Hotfix 6 includes three updates.

Functional Issues Fixed in Hotfix 6

LEM Manager updates in this release:

  • Fixed an expired certificate for connector updates.

  • Updated the partition delete process to prevent it from running before the LEM Manager starts up.

  • Fixed a NullPointerException error caused by the partition delete process.  
     

LEM Agent updates in this release:

  • No new LEM Agent updates.

Issues Fixed in Previous Hotfixes

The following fixes from Hotfix 1, Hotfix 2, Hotfix 3, Hotfix 4, and Hotfix 5 are also included in this hotfix:

  • Added several updates to improve logging and enhance supportability.

  • Upgraded Tomcat to version 8.0.44.

  • Fixed an issue with free disk calculations.

  • Upgraded the SSH library to support AES encryption by default.

  • Windows Server 2016 nodes are now labeled properly in the LEM console. Previously, the LEM console listed computers running Windows Server 2016 as Windows NT (unknown).

  • Fixed a hard-coded credential vulnerability (CWE Classification 798). 

  • Addressed several security issues.
  • Made multiple updates that improve communication with the LEM Agent.
  • Fixed an issue related to free disk space management. Previously, LEM might under-report the amount of disk space remaining if raw logging was enabled.
  • Added updates that improve the performance of some connectors. In addition, fixed a bug that caused a connector to not function properly.
  • Fixed a CMC command vulnerability.
  • Scheduled nDepth search: results limited to 50,000.
  • Fixed an ImportCert error that occurred when importing certificate after a command failure.
  • Fixed an issue that displays the IP address instead of the FQDN/hostname on the "All Installed Agents" screen.
  • Fixed an issue that occurred when an L4 Database appliance started with only 128MB of memory.
  • Updated the Java platform to the latest version.
  • Fixed an out-of-memory issue that occurred when sending alerts to the console. The fix improves performance when a large number of events are sent to the console.
  • Fixed Agent–Manager communication issues: periodic disconnect and others.
  • Fixed an issue with nDepth log retention (logging missing date in raw records).
  • Fixed an issue that prevented logging in to LEM if using UserPrincipalName with a custom Alias, or SAMAccountName with NETBIOS.
  • Added the ability to use sub-alias LDAP environments.
  • Removed field limitations in the normalized alert database.
  • Fixed a log rotation issue that caused connectors to stop working if log lines were too long.
  • Fixed a single sign-on (SSO) issue that occurred if a Kerberos ticket was unusually long because a user belonged to many groups.
  • Added the ability to configure custom LDAP groups for authentication.
  • Set an Agent memory limit for Agents upgraded from older versions.
  • Fixed other Agent–Manager communication issues.
  • Added improvements to assist customer support, including improved logging, and added diagnostics.
  • LEM can again download threat-feeds IPs. This issue occurred when the threat-feeds server certificate changed.
  • Updated the Active Directory (LDAP) configuration. You can now have a domain name containing a dash.
  • You can now recover a password when HTTP is disabled.
  • Exceptions during a fast evaluation are now logged.
