Known Causes of Corruption in InterBase Databases

Server crush during "Changing metadata while database in use" is well known since SuperServer architecture was introdiced (IB 4.2 for Windows).Yes, itself it can't corrupt database, but if it crushes server, it can cause database corruption, since server is being terminated by itself during work.If you know, InterBase 5.5 introduced mechanism that described in Data Definition's Guide "altering and dropping procedures in use" section. This was exactly made to prevent server crush during metadata change.Of course, I do not recommend to change metadata at production server while it serves user requests, too.
