Hi,

The issue is surely related to memory allocation where segment 6 represents PXA shared memory

ERROR => [CreateOsShm] CreateFileMapping(6,30000000 KB) failed with Err=1455

Kindly refer the below notes for further details

1790345 - PXA_NO_SHARED_MEMORY

1997262 - The shadow instance won't start up. System dev_w* trace
files highlight error message 1455

I sugest to consider the physical memory allocations at server level also for which you need to refer the installation guides on memory parameters for windows.

Hi Domnic,

A  *** Allocation of PXA failed.

A  *** shared memory available.        
A  *** Please decrease value of profile parameter
A  *** abap/buffersize and restart the system.

If you see the above the log, the allocation of PXA failed because shared memory in size 639872K in not available.

So, you need to decrease the value of abap/buffersize and refer SAP note 307976.

Have you tried that ?

For that make sure you have enough paging memory in your windows system -
