WSAENOBUFS: No buffer space available

[Former Member]

Hi,

All of the sudden our PI 7.0 system (dual stack) started to report errors: WSAENOBUFS: No buffer space available.

This is the dev.trace on server0 and server1:

[Thr 5496] ***LOG Q0I=> NiIConnectSocket: connect (10055: WSAENOBUFS: No buffer space available) [nixxi.cpp 2897]

[Thr 5496] *** ERROR => NiIConnectSocket: SiConnect failed for hdl 827/sock 6728

    (SI_ESYSCALL/10055; I4; ST; xxx.xx.xx.xx:xxxx) [nixxi.cpp    2897]

This error messages is written continously. SAP is green and running, but the J2EE part (runtime workbench) is unstable. In all the documentation I can find, the problem is characterized as Windows issue. One suggestion is to change the registry key, but I can't see why it is necessary because the system has been working perfectly fine until recently: WSAENOBUFS: 10055: No buffer space available - ABAP Development - SCN Wiki

Have anyone experienced this problem before?

Thanks!

M.

Hello Moye,

Did you change network configuration recently? Please try to set default domain in tcp/ip configuration, You can also enable/disable ip v6 on that interface.

I hope it helps.

Hello Moye,

You already have a root cause and a solution as well, if its so well documented, there is no other option but to change the registry value.
