Thanks, i'll run it over weekend.

I can't comment right now AV and other errors i skipped here, but i not ignore it. It all will be investigated and hopefully fixed.

I've read firebird.log you provided at should say that real errors only those that looks like :

Index 1 is corrupt on page 2547559 level 1. File: ..\..\..\src\jrd\validation.cpp, line: 1667

Index 1 is corrupt on page 2547559 level 1. File: ..\..\..\src\jrd\validation.cpp, line: 1657

All other errors is orphaned pages and orphaned record versions which have no effect on database. Its just a waste of space.

Index errors above was fixed recently (remember my build of 2.1.4 ?) but *after* FB 2.5 RC2. So, please, install current snapshot build of v2.5 and index errors should gone.
