Hey Kishore,

There is a large amount of CFO.

First, manually fix this, second, could you get rid of additional log
messages you have added to the info logs, it makes it harder to parse the
logs. Third, change the max_prach_offset_us  = 200 in the enodeb.conf.

Finally, set your zero_correlation_zone_config = 0 in your sib.conf.

See how this looks.

Regards,
Justin
