Good Day Amal
The problem you have is with the Extended Memory.
The system is not set with the SAP recommended settings.
You have set the value of ztta/roll_extension to 300000000
This is not even 1 GB
SAP recommends to set the value to 2 GB where in you set it to less than 300 MB
Please read this SAP Note and set the parameter accordingly
Note 146289 - Parameter Recommendations for 64-Bit SAP Kernel
Additionally consider checking the parameter abap/heap_area_dia as well.
Back to the saposcol not running.
Please provide the output of the following command
