| In various tests after 100+ stalls in each one, valgrind doesn't find any leaked memory. When a peer is shutdown during a stall memory might be marked as lost due to the reference spaghetti confusing valgrind or shutdown not freeing the memory correctly in that case... but it's shutdown, the process is going to die and only one block seems to be missing anyway. | |
