NIM备份AIX系统报错

NIM服务器系统版本：AIX7.1

在进行系统备份是报出如下错误：

+---------------------------------------------------------------------+

                System Backup Image Space Information

              (Sizes are displayed in 1024-byte blocks.)

0042-001 nim: processing error encountered on "master":

   0042-004 m_mkbosi: error on system call

A connection with a remote socket was reset by that socket.

遇上这个情况，我重新试了几次都一样。是连接的目标服务器的问题吗？
