如何解决AIX tar命令套接字错误?

在AIX环境中工作时,我发出以下tar命令并接收套接字错误。

问题2。我是否可以依赖tar文件来包含除出错文件以外的所有文件?

 $ tar  -cvf /post_patches.tar /xyz 
   tar: /xyz/runtime/splSock6511 could not be archived
   tar: /xyz/runtime/splSock6507 could not be archived
   tar: /xyz/runtime/splSock6510 could not be archived
   tar: /xyz/runtime/splSock6506 could not be archived

 $ ls -asl spl*
   0 srwxrwxrwx    1 myuser   myuser            0 Nov 19 09:41 splSock6506
   0 srwxrwxrwx    1 myuser   myuser            0 Nov 19 09:41 splSock6507
   0 srwxrwxrwx    1 myuser   myuser            0 Nov 18 14:19 splSock6510
