If you have not seen yet here some recommendations: https://yandextank.readthedocs.io/en/latest/install.html

But for more guaranteed result try these commands, especially the first one (you could use more adequate number):

echo 10000000 >  /proc/sys/kernel/pid_max
sysctl -w net.ipv4.ip_local_port_range="500   65535"
echo 10000000 > /proc/sys/kernel/threads-max
echo 10000000 > /proc/sys/fs/file-max
echo 10000000 > /proc/sys/vm/max_map_count
echo 20000500 > /proc/sys/fs/nr_open
