Shadow file corruption occurs occasionally.
Once this incident occures, I can't access my database;
So, I open a corrupted shadow file by binary editor.
In correct shadow file, I think HDR_root_file_name is stored at hdr_data area.
But in my currupted shadow file, only HDR_sweep_interval is defined in hdr_data
area,
HDR_root_file_name is not defined.(disappeared)
Therefore, BUGCHECK(163) will happen, and connection is end.
This incident is a bug or known issue?
Furthermore, firebird.log is below.(selectively)

Database: {my root database file path}
internal Firebird consistency check (root file name not listed for

localhost (Server) Thu Sep 9 15:38:08 2015
shadow {my shadow file path} deleted from database {my root database
file path} due to unavailability on attach

I create shadow file with no options, like below.
create shadow 1 '{my shadow file path}';
