It was unclear whether to specify the version of 389ds with the version specified above, so the OS and 389ds packages that occurred below are listed. Please verify.

I am writing to inquire about the issue mentioned in the subject line. When executing the command specified in "Issue 1," following the steps outlined in "Execution Command 1," the LDAP process (dirsrv@389ds) encounters an error and stops, as described in "Error Message."

Furthermore, as per "Issue 2," after executing the command specified in "Execution Command 2" following the steps outlined, though the addition of data is successful with the sort order "uid:2.5.13.2," the process encounters a similar error upon restarting.

Could you please provide insight into the cause of these errors and any possible solutions?
