Description

We found a instance for catalog file as below:

rec #28689 type=1064553b len=64 offset 1844224
Header size : 8192	 llh_size : 64
Time : Fri Dec  6 08:50:22 2024
Number of records: 1	cat_idx: 33083. 	last_idx: 28689
Flags: 0x12
Target uuid :
-----------------------
#28689 (064)fid=[0x1:0x1dc53:0x0] path=oi.1/0x1:0x1dc53:0x0

These is only record, but the cat_idx still point to 33083. In current implementation, if some reason cause next record cancelation doesn't execute. Then llh_cat_idx will never be moved.
