columns. If you choose to use a replacement and there is a patch shown in the
recommended column, this is the patch you should use.
Patch warnings
A patch warning is a notification that a patch causes or exposes adverse behavior. Patch warnings
provide specific information about this incorrect behavior, as well as other important details and
recommendations. This information helps you to make decisions about the patch, such as whether
to install or remove a patch with a warning from the system.
The warning field
You can find patch warning information in the Warning field of a patch's patch details page or
patch text file. This field exists only for patches that have a warning. The Warning field is the
definitive source of information about a patch warning. The following screen shows part of the
Warning field for patch PHKL_30065.
Warning: 04/01/22 - This Critical Warning has been issued by HP.
- PHKL_30065 introduced behavior that can cause a panic on
systems configured with greater than 32 GB of device swap.
The behavior will occur only if all the following factors occur:
- The system is configured with more device swap than is
supported by the current value of the swchunk(5) tunable kernel parameter.
- The system has 2 or more swap devices.
- Pages are actually written to the non-primary swap device which
exceeds the swchunk(5) supported limit.
