tuxedo服务动态添加问题

Question

进入tmconfig，编辑保存退出出现unexpected，确认操作后出现ERROR是什么原因？错误信息如下：
Enter editor to add/modify fields [n]? y
"/tmp/Ta9311" 1 line, 1 character
TA_SERVERNAME   get_info
TA_SRVGRP       GROUP1
TA_SRVID        112

Line 1: unexpected newline - no field value

Enter editor to correct? n
Perform operation [y]? y
