WebAction value is an int, so depending on your platform the size might vary, but it's probably not 1byte. Check where you're copying peerId to, I bet buffer + sizeof action_value is not the 2nd byte of the char array. And since that's a uint32, it will copy 4 bytes which will probably fall off the end of the 5byte buffer. stash osrs wiki
