Fault Tolerant Heap

Performance

50% of crashes have heap management functions on the stack (buffer overruns, double freeing, touching the block after freeing, freeing stack/global variables etc.)It gets activated only for apps that crash often (ex: 4 times / hour) and only for crashes related to the heap manager:• Zeroing allocations • Padding (small overruns)• Delay freeing (keeps portions of 4 MB)• Don’t freeOn crash calls home and if a solution is present it applies a applies FTH Shim. It backs out if its not doing any good (ex: 15 times).

Process Reflection

Performance

A large process takes a long time to write a memory dump to the HDD. Achieve quicker memory dumps by copping in memory.Based off the UNIX “fork”.
