SCODE-5 assigns a fixed sector size (usually 4KB) to Block 2. Poorly optimized logging routines or memory leaks can exceed this boundary, causing a segmentation fault. The solution is to audit custom application code for unnecessary writes to the 0x2xxx memory address range.

Block 2 is specifically used to link valid matric subjects to their respective categories. This is essential for students using an "iEnabler" or online portal, as the system relies on these links to display the correct subject options during the application process.
