15:52:10 [2024-05-24T19:52:10.913Z] ghprbPullLongDescription=Current heap allocation direction for zLinux is bottom-up. The motivation for this is on Z platforms shift operation executes faster for smaller shift value. However with bottom-up direction object heap takes all available memory below 4G bar. This does not allow Suballocator to expand if necessary and might lead to OOM below 4G bar. The intention for this fix is to improve this situation. Switching to top-down increases chances that less memory below 4G bar is going to be used (but worst case scenario still be the same as now). In order to keep smaller shift performance benefit an allocation shift scheme should stay 0-1-2-3-4. All other platforms still use 0-3-4. The behaviour for all other platforms has not been changed.
