Thanks Henning,

1. I tried changing the numbers keeping '#' by default number was 64 and 8 changed to 96 and 16
# Amount of shared and private memory to allocate
# for the running Kamailio server (in Mb)
#SHM_MEMORY=96
#PKG_MEMORY=16

2. Then got a different message when restarted the service in status;
root@ubuntu18-04:/etc/default# systemctl start kamailio_pcscf
root@ubuntu18-04:/etc/default# systemctl status kamailio_pcscf

3. Restarted the service again now same error was back of 'out of memory'. So now changed SHM_MEMORY PKG_MEMORY number with and without '#': 
I noticed that whenever starting service takes little bit time it shows the different message, the above one, not the 'out of memory'  and this happened only twice, generally the service starts quickly and now only showing whenever I am restarting the service:

Hello Jack,

the memory errors indeed don't look good. Check your SHM and PKG memory size and try to increase it. At Debian/Ubuntu this should be configured at /etc/default/kamailio

Cheers,

Hello Jack,

as you can see in the logs there is an error in the cfg file. Have a look to the kamailio logs (e.g. in /var/log/messages or /var/log/syslog) to get more hints about the cause.

Cheers,

Henning
