Hi S Kumar,

The log here shows two errors -

1.

[Thr 01] Profile configuration error detected, use temporary corrected setup

[Thr 01] Shared Pool 10: ipc/shm_psize_10 = 19880000 (too small)

[Thr 01] Shared Pool 10: (smaller than min requirement 130168712)

To resolve this, set up your ipc shm size as recommended here. You can check that by running

sappfpar check pf=<webdispatcher profile>

and do a clean restart of the system. Clean restart means by running "cleanipc" command with this syntax -

cleanipc <Instance number of webdisp> remove

Also run it for SCS instance number and restart.

2. [Thr 01] *** ERROR => NiIBindSocket: could not delete file '/tmp/.sapstream65000' (hdl 0; errno=1) [nixxi.cpp    3214]

Look for two things here -

1. space in /tmp filesystem by using " df -k /tmp" and see it is not full.

2. Permission of /tmp. It should be 755.

Please go through these steps. These will help you in getting back your system up and running.

Ashutosh Shukla

HI,

This error had been came for the first time from the past 5-6 years which we are performing the activity regularly ,

we had not even done a single change in the profile parameters or any thing , but we cant understand the cause for this issue either we had changed the permissions of the users or the files, and we had followd the process as we are doing earlier.

The strange thing i need to understand is y this issue automatically all of sudden with out any changes.

what caused to rise this issue?

could any one help me in that view

Thanks

Have you cleaned up the shared memory as suggested by Ashutosh?

Have a clean restart of your system.

stopsap --> cleanipc --> ipcrm --> startsap

Vishal

HI Vishal ,

I think cleanipc may work , but why should i do , what is making me to perform that extra command .

I need to know why this issue came

Reason is most important to me than the solution.

Pls assist me in understanding the issue and the cause.

Hello Kumar,

Shared memory is allocated when you start the SAP instance.But in your case somehow it is not able to clean the shared memory segments.

So in order to cleanup those sahres memory segment, I've asked you to do cleanipc.

But For web dispatcher, you can start it with cleanup command:

sapwebdisp
pf=<profile name> [-f <trace file> -t <trace level>  -cleanup -shm_attach_mode <mode>
-auto_restart -version]

<mode> = cleanup

For more info, Please gothrough
