For the past couple of months I have been making my own modpacks, and running them on a server for me to play with my friends. While I got many errors during this period of time they were fine as I fixed them. However this past month I have made a new modpack which has a bunch of magic mods (Ars Magica, Thuamcraft, etc.) I was surprised to find that occasionally one of the players on my server crashed randomly by just playing (and not doing anything special) after trying to connect he would get disconnected and get "Internal Server Error". Now this has happened to me, and two other people. I have fixed this by deleting the "player.dat" (kman1000mlg.dat, doyoumindcraft.dat) file and restarting the server. Obviously this is stupid as all of your research disappears along with the stuff you had on you. So I was wondering if there is something to do to fix this.
