Dear vlad,

So about the bug in FB2.1.4 you can download the demo project on
ftp://ftp.arkadia.com/firebird/

the database is just come out from a restore (so it's frech and clean). you simply need to put the database on one computer and let it running for 2 or 3 days (wait that the database size grow around 11-12 GO) and after you will have some index in error ...

also the problem look like that is still present in Firebird 2.5 !

today i receive again this :


Thu Apr 15 12:28:27 2010
INET/inet_error: read errno = 10053


Thu Apr 15 13:36:26 2010
Fatal lock manager error: invalid lock id (2413696), errno: 0


Thu Apr 15 13:36:26 2010
INET/inet_error: select in packet_receive errno = 10093


Thu Apr 15 13:36:26 2010
INET/select_wait: select failed, errno = 10093


Thu Apr 15 13:36:26 2010
SRVR_multi_thread/RECEIVE: error on main_port, shutting down


after i decide to shuntdown all the client to copie the database to another harddrive to do some validation on it, but as soon as i restart the client i receive this on the server :

Thu Apr 15 18:25:23 2010
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.


Thu Apr 15 18:25:23 2010
INET/inet_error: select in packet_receive errno = 10093


Thu Apr 15 18:25:23 2010
INET/select_wait: select failed, errno = 10093


Thu Apr 15 18:25:23 2010
SRVR_multi_thread/RECEIVE: error on main_port, shutting down

after the server work again ok ...

so i finally launch the validation on the copie of the database and i receive this time this error :

Summary of validation errors

Number of record level errors : 1
Number of index page errors : 24
Number of database page errors : 54

:( :( :( :(

i need to say that this bug become to destroy my life :( i need a super hero :(


Thanks for all Vlad !!!!
