Using the DNS Techpack for all my Mods.
Never had this problem before, seems to randomly crash with these errors.
I have noticed two things;
firstly everyone who crashes on the server crashes at the same time with this error
secondly the people who are crashing seem to be PC users; 4 people on the server, 3 of them are PC users and one of them uses a MAC. The three PC user crash with this error and the mac user has yet to crash.
This ticket is invalid as it relates to a modded or 3rd party client/server.
Any non-standard client/server build needs to be taken up with the appropriate team, not Mojang.
Any plugin issues need to be addressed to the plugin creator.
This site is for addressing issues related to the base unmodded MineCraft.
