SAPGUI problem :10035 wsaewouldblock : resource temporarily unavailable

[Former Member]

Dear Experts,

One of our colleaque facing the SAPGUI Error "10035  wsaewouldblock : resource temporarily unavailable" when he is trying to logon to the SAP system.

Do I have to use telnet hostname port number (dispatcher TCP port number, like 32XX) to check if the firewall opened for this port number? Any other checks required?

Any ideas, please?

Thanks & best regards,

Sreenu

Hello,

"Resource temporarily unavailable":

This 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, within the specified TIME_OUT parameter for this request. 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, on a misconfiguration of the 'hosts' files at your workstations that are connecting to the server, etc.

You can review the following SAP notes:

Also, do you have Quality of Service (QoS) enable? Altough this SAP note is targeted to lower versions of Windows OS, it might provide an useful tip for the resolution of the problem:
