WSAEWOULDBLOCK: Resource temporarily unavailable. Very strange thing happening

[Former Member]

Hi All SAP Gurus,

I'm having a very strange problem. Can someone out there help me?

I'm using SAP by connecting my PC to a VPN. If I am connected in my office through the WiFi of my Laptop everything works perfectly. But if I connect to the same router of my office using the LAN cable, as soon as I try to LogOn I receive the message

WSAEWOULDBLOCK: Resource temporarily unavailable

What can be the problem? Thank yu all in advance for your kinfìd effort!!!

Hello Andrea,

The  "WSAEWOULDBLOCK Return code 10035: Resource temporarily

unavailable" error  is returned from operations on nonblocking sockets that

cannot be completed immediately, for example recv when no data is queued

to be read from the socket.

It is a nonfatal error, and the operation should be retried later. It is normal for WSAEWOULDBLOCK to be reported as the result from calling connect on a nonblocking SOCK_STREAM socket,

since some time must elapse for the connection to be established.

In any case, seems to be caused by the configuration of your network,

be it a failure on the DNS server, or a misconfiguration of the 'hosts'

files at your workstations that are connecting to the server, etc.

Can you check if the error is not caused because of a hostname

problem:

124562     Hostname resolution problems (DNS timeouts).

Note 500235 shows how to run NIPING:

"First start the NIPING server on computer A (e.g., the Application

Server) with the command line:

  niping -s -I 0        (the last character is zero, not the letter O)

Then start the client (e.g. on the front-end machine) with the command:

  niping -c -H <nipingsvr> [ -B <buffersize> -L <loops> -D <delay> ]"

I hope this clarifies the issue for you
