Summary :
SAP Note highlights issues experienced by users, such as system hangs, poor performance, and instability on ABAP application servers. The problems, reported over several months, are linked to misconfigured applications and poorly programmed reports that excessively allocate memory. Specifically, situations where 13 GB of heap memory was allocated on a system with only 4 GB RAM have been identified. On 64-bit Windows platforms, the `abap/heap_area*` parameters were previously unlimited, allowing processes to use up to 2 GB of extended memory and potentially exhaust system resources, leading to program and OS failures. The proposed solution adjusts the default settings to restrict memory allocation, enhancing stability.
