Abstract
Description
IBM has seen multiple issues processing normal network traffic on recent code levels (affected levels listed below). Several timing-related issues can occur, including but not limited to:
- System crashes when routes expire due to dynamic routing
- Memory leaks or crashes when the cached_routes feature is enabled on AIX. (# no -o cached_routes)
- System crashes due to synchronization issues between threads referencing the route entry in TCP/IP code

*The HIPER ifixes in this column include the conflicting kernel and TCP/IP kernel extension security vulnerability fixes from: https://www.ibm.com/support/pages/node/6847947
This table describes which active levels are affected and where to obtain fixes.
Before the APAR fix is available, an interim fix (iFix) is available for each affected level.
The available interim fixes might apply only to the latest Service Packs. If a custom interim fix is required, contact IBM Support. The interim fixes can be downloaded from the same location by using HTTPS or FTPS.
