When I run tcode sm21, there're many errors about "Operating system call gethostbyname failed (error no. 2 )"
The specified operating system call was returned with an error.
For communication calls (receive, send, etc) often the cause of errors
are network problems.
Documentation for system log message Q0 I :
It could also be a configuration problem at operating system level.
(file cannot be opened, no space in the file system etc.).
Additional specifications for error number 2
Name for errno number E_UNKNOWN_NO
The meaning of the value stored in 'errno' is
The value which occurred here is unknown to the SysLog system.
Either there is an incorrect error number in the SysLog message, or
the tables TSLE2 or TSLE3 are not completely maintained.
Do anybody help me to solve this problem?
