I am sorry for double posting but this is an important update which needs to be seen by all the users of my mod.
These issues will be handled as soon as possible. Server code is pretty fresh at this point and with problems like these it will mature up. These are the datas I could find while working atm(Hell yeah multi tasking!). After I finish my work for the day I will be able to deep dive into this mess and implement a proper firewall system for incoming of spam and empty datas. Soon there will also be version controlling system implemented to make sure that only up-to date users can join the server so that they can't abuse the old bugs/glitches that are present in old clients. This might push back some of quality of life features that I have been working on a little bit later in the release schedule, just to let you all know.
Please, do not post IP addresses or any personal data on forums (especially because there is mine
). I removed the screenshots with IP addresses of your users.
Concerning the crash, I am most likely the reason of this. Concerning the memory dump, this is because your program must have a flaw somewhere that must make some infinite loop or something as I absolutely did not do any stress test. Please, also do not that I did not use any sort of client, but simply opened raw sockets to your server and sent a few random bytes.
Finally, you do not need to configure a firewall but a proper input sanitization in your code, which clearly is not the case yet.
Edit: The no message spam you have received sounds like a common socket closure improper check. You must be reading message from a socket that has actually been closed.
