I upgraded fb 1.55 to FB 2.12 since a day and I've got this log:

SERVER001 (Server) Tue Jun 09 17:51:58 2009
Access violation.
The code attempted to access a virtual
address without privilege to do so.
This exception will cause the Firebird server
to terminate abnormally.

Environnement:
Windows 2003 Server R2 Standard Edition SP2
Xeon 2.66 Ghz, 3.25 Go RAM
Database 6 Go
40 ~ 60 simultaneous Client/Server users

I stopped fbserver process with procexp (sysinternals tool) after waiting a while and restarted it. The validation reported this:

Does a backup/restore will solve the indexes problem ?
is the "mini-crash" is due to fb2.12 migration ?

thanks for any help.
