Question Server issue and crashing

[ilnert]

Hello, I don't understand much about java developtment and issues, I just recently created a server with some plugins

It was fine before but now I get problems with my server, long connection and pinging to the server, then eventually server just crashes and console is filled with these errors:

also right after running start.bat file I basically dont get any critical errors, but when first player connects - the server start lagging and console
says this:

[12:53:21 WARN]: Can't keep up! Is the server overloaded? Running 18169ms or 363 ticks behind

What could be the issue? Does this have something to do with the plugins? And how do I identify which plugins are causing the problems?
