Unable to do any hadoop fs operations

Hi

getting below error while doing any hadoop fs operations:

Java HotSpot™ 64-Bit Server VM warning: INFO: os::commit_memory(0x0000761f4fb00000, 175112192, 0) failed; error=‘Cannot allocate memory’ (errno=12)

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

Native memory allocation (mmap) failed to map 175112192 bytes for committing reserved memory.

An error report file with more information is saved as:
