How to run load test for 3000 users with 50 loops in jmeter?

I tried to run a load test in jmeter with 3000 users and 50 loops.But it shows this error.

[9.746s][warning][os,thread] Failed to start thread - pthread_create failed (EAGAIN) for attributes: stacksize: 1024k, guardsize: 4k, detached.
Uncaught Exception java.lang.OutOfMemoryError: unable to create native thread: possibly out of memory or process/resource limits reached in thread Thread[StandardJMeterEngine,5,main]. See log file for details.

I also tried to increase the Heap size using- HEAP:="-Xms2g -Xmx2g -XX:MaxMetaspaceSize=2g"

But the same issue of OutOfMemory persits. Thanks for the help
