Hi
I am running LISF v7.5.0 and in the 5th step i.e DA_proc_SMAP , I am getting a warning . I have checked the target ldtlog file of this step and I didn't see this error. Can anyone please help me why am I getting this error and how to resolve it.?

EDIT: I am getting this error in the 4th step too . I am attaching the config and log file for it too.

The ldtlog file is too long , so I have shown only the starting part of it. I am attaching the ldt.config.smapobs_cdf and ldtlog file here.
