Hi,

See the following SAP note.Hope this will help you..

Note 34116 - Syslog: "Operating System call xxxx failed"

Also check your network connectivity is not having any interruption (packet loss.) to server the Client-Server communication.

Check dev_rfc log file, check any of the program was using any RFC .

Regards
