Issue/Introduction

We have got multiple error on nas causing high disk utilization and multiple probes including ems, sdgtw, qos_processor ,etc. stopped with error.

Environment

Release : 20.3

Component :

Cause

From the error dump file 
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (malloc) failed to allocate 1048576 bytes for AllocateHeap
# 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)
#   Set larger code cache with -XX:ReservedCodeCacheSize=
# This output file may be truncated or incomplete.

#  Out of Memory Error (memory/allocation.inline.hpp:61), pid=11764, tid=1716

Resolution

 Possible solutions as explained in core dump itself:
    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)
    Set larger code cache with -XX:ReservedCodeCacheSize=
