There is insufficient native memory for the Java

Issue

• There is insufficient native memory for the Java
• We are getting below Error when we try to start servers. Free -m shows that
  we still have 38 GB Space un-utilized.

java.lang.OutOfMemoryError: classblock allocation, 10775624 loaded, 10752K
footprint, in check_alloc (classalloc.c:215).

Attempting to allocate 2G bytes

There is insufficient native memory for the Java
Runtime Environment to continue.

Possible reasons:
  The system is out of physical RAM or swap space
  In 32 bit mode, the process size limit was hit

Possible solutions:
  Reduce memory load on the system
  Increase physical memory or swap space
  Check if swap backing store is full
  Use 64 bit Java on a 64 bit OS
  Decrease Java heap size (-Xmx/-Xms)
  Decrease number of Java threads
  Decrease Java thread stack sizes (-Xss)
  Disable compressed references (-XXcompressedRefs=false)
