Adjusted the profile parameter abap/buffersize from original value 600000 to 800000, but no difference and also restarting the server does not solve the issue.
Any ideas ?
The value of the parameter rdisp/PG_MAXFS is increase to 262144 as explained in attached note 133909.
Added the value /USERVA=2800 to the boot.ini as recommended in Note 990538 "WSAENOBUFS error on Windows" and not /Userva=3030 as mentioned in http://support.microsoft.com/kb/810371/en-us, because no exchange server.
Rebooted SAP and windows server and in Task Manager the following values.
Before reboot:
Commit Charge Limit
18449052
Commit Charge Peak
18443932
After reboot:
Commit Charge Limit
26829460
Commit Charge Peak
18705576
Page file on server is 2048 MB and not increased.
PHYS_MEMSIZE
9008
em/initial_size_MB
13100
em/address_space_MB
512
em/blocksize_KB
4096
abap/buffersize
800000
After reboot no error messages, will monitor the system today if it will occur again.

before reboot even you stopped the system probably there left some processes holding SHM and occupying the page file space. After reboot the space was freed. So far you do not need to change any SAP memory parameter.
Hello,
When we checked the paging memory, which was more than that was recommended at the OS.
We increased the abap/buffersize parameter, but no success.
We had nothing but last option to restart the server, restarting the server helped resolve this issue for me.
Regards,
Omkar

Monitored for a day and issue is solved.
Also found more details about the cause of the issue.
The pagefile settings were no longer good after a restore.
On 😧 drive is normally a total of about 10 Gb pagefiles. There has been a restore, where this setting was NOT restored:
The pagefile folders were not in the backupselectie. Misconceptions therefore wrong backup configuration.
The pagefiles are now well established and the backupselection been corrected.
Thanks Markus and Yaroslav for your quick response and answers.

what about this
I *** ERROR => CreateOsShm CreateFileMapping(6,800000 KB) failed with Err=1455
ERROR_COMMITMENT_LIMIT: The paging file is too small for this operation to complete. http://shmnt.c 2130
I *** ERROR => ShmCreate: Create (6,819200000,1) failed http://shmnt.c 469
did you try to increase the page file?
What you see in Task Manager for
Commit Charge Limit
Commit Charge Peak
if SAP system is stopped (and started)?

You are getting this error because the system started in emergency mode.
how big are you other buffers? You may reach the 2 GB border. Do you have "/3GB /USEVA:2600" in your boot.ini?
