I'll try it, but later. I hope it's not very dangerous.

Hi,

Try "install" current snapshot of Firebird 2.5. Go to firebirsql.org downloads on the left you have snapshot builds. After download you must stop server and replace files. After replace start FB server. You should have version 2.5.3.26715 or greater

Karol Bieniaszewski

No, I mistak, there are records with message, that sweep is complete, but between messages of start and finish always exist messages, that "Internal Firebird consistency check (record disappeared (186), file: vio.cpp line 408)".

Before It gbak retoring this "gbak:    restoring privilege for user SYSDBA "

I delete all indexes because I can't activating indexes one by one, and I can't delete them, I can't activating FK, I can activating only PK. I should to delete some FK(about 3 or 5 not more) and indexes from system tables manualy, because I can't delete them by sql.

Because some our consumers is old they using Firebird 2.5.1, other use 2.5.2. I can't see any dependence between achitecture of firebird and version of firebird. 

Later I try to copy log on validating errors.

WHY? Firebird 2.1 and higher restores all indices it can, and show error on indices that it can't create
(by the PK or FK violation caused by broken records).
So, after restore (without -i) option you just need to check restore
output for errors, then check non-active indices in the DB, and try to
fix data and activate those non-active indices.
