Illumio Core What's New and Release Notes for Release 24.2

Upgrades from 22.5.32 now succeed without ruby core dumps (E-124881)

Ruby 3.1 used by the PCE starting in 23.2.20 introduced a memory compaction feature that can cause crashes or core dumps when processing a large number of workloads. To address this we have patched Ruby to avoid this functionality in 24.2.21+A1. Notably, the Ruby maintainers themselves have done this in Ruby 3.2. This is therefore a temporary requirement until the customer migrates to 25.x which uses a later version of Ruby that should not have this issue.
