sbwp in error with Operating system call gethostbyname failed

[benoit-schmid]

Hello,

In a ECC 6.04 system, we have several errors, in sm21, for a specific a user,

with the following information:

TCode = SBWP

Text = Operating system call gethostbyname failed (error no. 0 )

If I look in the Sap OS log (dev_w2.old), it shows the following:

M ***LOG Q0I=> NiPGetHostByName: hostname '6045:262f:0:f0b' not found: gethostbyname [niuxi.c 1477]

M ***LOG Q0I=> NiPGetHostByName: hostname '/0' not found: gethostbyname [niuxi.c 1477]

M ***LOG Q0I=> NiPGetHostByName: hostname '/1' not found: gethostbyname [niuxi.c 1477]

M ***LOG Q0I=> NiPGetHostByName: hostname '/2' not found: gethostbyname [niuxi.c 1477]

...

M ***LOG Q0I=> NiPGetHostByName: hostname '/127' not found: gethostbyname [niuxi.c 1477]

M ***LOG Q0I=> NiPGetHostByName: hostname '/128' not found: gethostbyname [niuxi.c 1477]

Could you please tell me how I can diagnose this problem?

How can I see which mail in the Business Workplace is causing these errors?

Thanks in advance for your answer.

What do you mean by entries maintained?

For sure /1 is not in it as it not a valid host.

In our case, we know that it is the workspace that implies these errors.

We know that it tries to do dns to ip lookups for names that are not server names

(/1, /2, ...).

To go forward, I need to know which message in the sbwp is causing that and why.

How could I do that?

388193 concerns /SAPAPO/OM_REORG_DAILY -> Not relevant

124562 concerns bad dns config: You can have a good dns config but /1 will never exist

-> Not usefull

52967: idem as 124562

25941: idem as 124562

Thanks in advance for your help.
