Solution:

Add the JVM_ARGS configuration in your apache-jmeter-*.*/bin/jmeter.sh file

e.g. JVM_ARGS="-d64 -Xms24m –Xmx1024m -Xss228k -server"

Change the value of –Xms and –Xmx as per you requirement whereas put the min value of -Xss228k or –Xss64k

And

Change the ulimit –u (unix/REHL/CentOS) value to higher then number, what you have set in your jmeter script attribute num_threads value.

$ulimit -a

core file size           (blocks, -c) 0

data seg size           (kbytes, -d) unlimited

scheduling priority             (-e) 0

file size               (blocks, -f) unlimited

pending signals                 (-i) 128376

max locked memory       (kbytes, -l) 32

max memory size         (kbytes, -m) unlimited

open files                      (-n) 1024

pipe size            (512 bytes, -p) 8

POSIX message queues     (bytes, -q) 819200

real-time priority              (-r) 0

stack size              (kbytes, -s) 10240

cpu time               (seconds, -t) unlimited

max user processes              (-u) 1024

virtual memory          (kbytes, -v) unlimited

file locks                      (-x) unlimited

For changing the max user processes need to perform below command:

$ulimit –u 8888

$ ulimit -a

core file size          (blocks, -c) 0

data seg size           (kbytes, -d) unlimited

scheduling priority             (-e) 0

file size               (blocks, -f) unlimited

pending signals                 (-i) 128376

max locked memory       (kbytes, -l) 32

max memory size         (kbytes, -m) unlimited

open files                      (-n) 1024

pipe size            (512 bytes, -p) 8

POSIX message queues     (bytes, -q) 819200

real-time priority              (-r) 0

stack size              (kbytes, -s) 10240

cpu time               (seconds, -t) unlimited

max user processes              (-u) 8888

virtual memory          (kbytes, -v) unlimited

file locks                      (-x) unlimited
