Broken DB decrease performance. I don't find any dessapeared records of value 
of fields, but if I try to validate database, I see errors in DB.
 Hardware and OS always different, Firebird 2.5 with different 
architecture(cometimes classic, sometimes superserver). Force writes I check 
first and it's ON on for all servers.
 Some servers used RAID, but some others used only one HDD, it's depend from 
nu,ber of users and consumer abilities.
 When I restore DB I see the constraint error. My method of repair is more than 
easy recreating of FK and indexes. For the first I try backup and restore 
without garbage collection, than try different options of using gfix, last I 
try gbak -b -v -ig -g database.gdb database.gbk, than I try to restore withput 
activating Indexes, than I try to delete all indexes, and FK, and than 
spep-by-step create FK and than indexes. When I restore FK I foun some records 
that break referential integrity. I delete this records and create FK. After 
that I use IBExpert and use SchemeCompair check all indexes, functions, key 
etc. After all this steps I check DB, doing backup and restore and if all ok I 
send it to the client.
 

 How I can attached log file here?
 In log file a lot of records look like this 
 PC (Server) Thu Nov 14 12:35:16 2013
 INET/inet_error: read errno = 10054

 I use firebird for my product and for some times my databases start break.

 

 OK.  What makes you think the database is broken?  Are you seeing error 
messages?
 What are they?  Are you losing data?  Seeing incorrect data?  Have you checked 
the 
 Firebird log for errors?
  
 I read a lot of forums about protection of my databases, but I don't 
understand what the reason of breaking.

 

 Nor do we, unless you give us some more information.  What version of 
Firebird?  What operating
 environment?  Which Firebird architecture (classic, superserver, super 
classic)?  What disk 
 architecture?  Are you using forced writes?
 

 

 DataBase is broken and can't be restored from backup, 

 

 If you can create a database, but not restore it, then the problem may be with 
a broken constraint.
 The error that gbak reports would be very helpful.
  
 but I can work with database and I can repair it(I need about 3 hours for 
repairing, because I need to recreate all indexes and foreign key and delete 
phantom records). 
 
 

  Phantom records?  What exactly are you doing to repair the database and why 
did you
 choose the method of recreating all indexes and foreign key relationships?
 
 
 
 

 I don't understand reasons for broken. Can you help me to find the solution of 
this problem? 

 

 Probably, with some more clues... 
 

 Maybe I must to show some log's or to turn on some logs that can help to fin 
solution?

 

 The logs you need already exist - firebird.log and possibly the system error 
log.  Without
 knowing more about your environment, I can't say where they are or what 
they're called.
 

 Good luck,
 

 Ann
