Is there a reason not to use the latest release of NoCheatPlus? In general the latest builds support all the recent Minecraft versions, swift overview of NCP vs. MC version: https://github.com/NoCheatPlus/Docs/wiki/Notable-Builds

Concerning the actual issue i am not sure, there are just too many changes in between to know how this would change with updating NCP. On the other hand the descritption indicates that either a major server lag spike or some kind of networking congestion (possible between server and backbone, internally within a data center) happened, if so many people trigger morepackets at once.

In any case i would first update NCP...

and Warning in console. Link : https://pastebin.com/tmrt1yEr

asofold commented 7 years ago

The console warnigns just state that some configuration paths have changed (for moved paths it's adjusted automatically, so nothing needs to be done on that account).

It could be some other configuration values have changed defaults now, so if the configuration has been taken from longer ago, it probably could make sense to just delete (rename) it and do 'ncp reload' to check for changes.

If you have a configuration with 'savebackconfig' set to false, the messages will keep showing up, though.

Concerning the issue, after it happens, could you run the 'ncp lag' command? It monitiors something like the last hour, concerning lag-spikes.

@jomjonejame In addition to above, i'd also like to know if the console warnings appear every five minutes (likely not, but better have asked...)?

Yes, every five minutes on "MorePackets: sent too many moves"

I'm removed old folder and get new folder, fixed this problem

There clearly are a lot of pretty heavy lag spikles.

Concerning the warnings repeating every five minutes: something is reloading NCP or even all plugins every five minutes? We would need to find what...

So do you have any plugin managing plugins installed or script-related stuff that reloads plugins or the entire server? Are other plugins getting reloaded as well every five minutes (compare to startup log...)?

Of course reloading is heavy...

Yes, every five minutes on "MorePackets: sent too many moves"

Would be nice to see a log to actually confirm this. Perhaps a /timings paste link as well.

Sounds like you're just having some plugin doing some very laggy things every 5 minutes. Perhaps some plugin either doing a web request every 5 minutes (I know adbolt did this every 3 minutes) or something intensive on the main thread.
