The server is so laggy that i hit the ground too hard from lag and died and lost all of my good gear.

We do not have enough information to find the cause of this issue.

While the lag occurs, please run /debug start, wait a while and then run /debug stop in order to create a debug profile. Afterwards, run /debug report.

If you do not have the permission to run these commands, open your world to LAN and enable cheats. If you're on a server, make sure that you're a server operator in order to execute these commands.

Then, please attach the profile results found in minecraft/debug/profile-results-<DATE>.txt, as well as the debug report found in minecraft/debug/debug-report-<DATE>.zip here.

This issue has been temporarily closed as Awaiting Response. Once the requested information has been delivered, the report will be reopened automatically.
