DaddyMac1075 Posted April 2, 2013 Share Posted April 2, 2013 I've been trying to figure out what is causing our family public tekkit server to "hang". I don't say crash, since everything seems to be working EXCEPT players cannot connect. The console seems to react to all commands, the TPS is high, and the processor utilization isn't extremely high. The tekkit server is the only thing running in this VM with 10GB RAM and access to all 8 Xeon cores in my Dell Poweredge Server. It's not a pile of junk desktop computer that I'm hoping to make a server out of - it really is commercial grade server hardware. Still, some plugins work which is why we see the hourly, "Sending money earned messages." "List" works, "gc" works, etc. To restart the server, "stop" works... but the restarter plugin doesn't seem to be working during these cases. (I type "rsset 0" and it fails to restart). The DynMap web interface even works during these times, however, the world time at the top keeps resetting. Example: 20:46, 20:47, 20:48, 20:46... I see it going in a loop as if the world time is stuck. We also see groups of "Reached end of stream" messages when the server is not working correctly, presumably when players try to connect. A few days ago, I wrote a script to watch for 5 of these in a row, and auto-type "stop" on the console to help restart the server for times when the timing works. However, yesterday, not even "stop" on the console worked. Below, there is a list a snippet from the console, output from "top" and a list of plugins within the log. 07:50:55 [iNFO] Sending serverside check to: loganmarkbunkers 07:56:49 [iNFO] Reached end of stream 07:57:35 [iNFO] Connection reset 07:57:35 [iNFO] loganmarkbunkers lost connection: disconnect.quitting 07:57:35 [iNFO] [MCBans] loganmarkbunkers has disconnected! 07:58:13 [iNFO] Reached end of stream 08:00:46 [iNFO] n;;10;0;n;0; 08:00:46 [iNFO] Creating empty config: /home/tekkit/plugins/Essentials/userdata/ maxilosxxx.yml 08:00:46 [iNFO] maxilosXXX [/22.214.171.124.5:55064] logged in with entity id 4863 at ([ world1] 332.5, 117.62000000476837, 427.5) 08:00:46 [iNFO] [mcjobs] Unable to load maxilosXXX.dat...
