these names are the path order that these functions are called on source code
in your example, that the client had sent an packet to server, where the server process this packet, then call PacketCharDelete -> addDeleteErr() -> ProcessMessage(). Maybe it can have more functions after this addDeleteErr() or maybe not, the code won't show more names because the error already had made the code stop its execution

but with these names you can presume that the error is something behind the character deletion packets/functions. Usually these ProcessMessage() errors occur when the message is not formatted correctly on sphere_msgs.scp (eg: the message must have args like %d / %s / etc but the user had removed it)
