Hello bukkit community, I'm getting a really annoying crash that happens once so often. It happens only when someone just joins the game, although one time it happened when an admin used the /seen command from Essentials. What happens after they join is: console error, but surprisingly the server doesn't just stop dead. Players can still move about on the server, and use chat for a little bit, but other than that, it's just perpetual lag. Can't destroy blocks, entities don't move, etc. Eventually after 30 seconds all players disconnect due to Java.io.socketexception: connection reset (or something like that). Here's the full details: Console log at the time server crashed: http://pastebin.com/d4mfgZ1K. Full crash report. A list of plugins can be found on Line 85. http://pastebin.com/BPMRpw5j Also, I'd like to point out a consistent feature in these crashes: in the console log, it's always something along the lines "net.minecraft.server.v1_5_R2.ReportedException: Loading NBT data". In Line 50 of the full crash report, "Tag name: blocks" and "tag type: 7" are always the same.
