11.2.0.4 RAC on RHEL7.9 , run root.sh on first node failed with crsconfig_lib.pm line 9379

Hi there,

I got a question with bothered me a long time.

ENV: RHEL7.9, Oracle RAC 11.2.0.4

first node root.sh : failed with crsconfig_lib.pm line 9379 .

I checked scriptagent_grid.log, and found something different from normal.

error:

and compare with the right on:

but there is no error in oc4j err log.

when root.sh failed, the 8888 port is listening.

any suggestion is appreciated.
