Updated description of  [CB-18382]. If you downloaded a previous version, please replace it with Version 3.

The updated release notes document now states: Kernel panics associated with the RHEL/CentOS 3.10.0-693.21.1.el7.x86_64 and 2.6.32- 696.20.1.el6.x86_64 kernel updates have been eliminated. [CB-18382]

But the original impact document: [CbR and CbP] Security Update for RHEL/CentOS Impacting Cb Response and Cb Protection Customers states that the problematic kernels are: 3.10.0-693.21.1 or 2.6.32-696.23.1

Please see the actual text in the release notes for the specific kernel information. Thanks.

Sorry I must not have been clear.  The quote is from the actual text in the updated release notes and differs from the original impact document (20.1 versus 23.1)

Thanks for keeping us on point here. It is indeed version 2.6.32-696.23.1. The document has been updated.

Uninstalled the previous version (6.1.3) with /opt/cbsensor/sensoruninstall.sh. So ended up with a lot of offline sensors in the gui. Therefor enabled VDI in the sensor group settings, to prevent having a lot of new sensors when i reinstalled. But this did only work for centos/rhel 6.8 and 6.9 and not for centos/rhel 7.3. Would be neat if it would work on 7.x as well

Version 4 includes additional known issues.

Memory usage in the cbdaemon may increase due to the activity of some long-lived processes. A workaround is to restart the long-lived process or cbdaemon. [CB-16064]

• Some of the tracking data in the kernel is using more memory than expected. This is most noticeable on systems with many long-lived processes. [CB-18105]

How do we determine its a "long-lived processes"? Just wanted to understand the criteria on when to restart the cbdaemon.
