Too many open files in system - IOException

My Server is Crash,The first i need to is to restart the server in order to make it running again because i can't even access the server when this happened and when i check i have the following error messages from traccar logs

2022-12-05 23:59:58 WARN: An exceptionCaught() event was fired, and it reached at the tail of the pipeline. It usually means the last handler in
the pipeline did not handle the exception. - Too many open files in system - IOException (...)

That's a significant number, but shouldn't be a problem if everything is configured correctly. You must be hitting some limit somewhere.
