SAS 9.3  Enterprise Miner 12.1
run node时出现错误提示：
could not create a new MP CONNECT session. Please check the SAS Command property of this project's server definination.

在run log里看到以下error:
NOTE: Remote signon to C2RGK718 commencing (SAS Release 9.03.01M2P081512).
ERROR: A communication subsystem partner link setup request failure has occurred.
ERROR: SAS did not start properly. Please ensure that your sascmd value does not attempt to run SAS in the background.
ERROR: Remote signon to C2RGK718 canceled.

装了sas/connect，而且也调大了destop heap。试了很多办法都解决不了，跪求大神帮忙。
