Hi,

 

 I have a legacy application written in Delphi XE6 using Firebird 2.5. Since 
several months ago have noticed that some times table records are not commited 
to database. I thougt that it was user mistakes with the application but not. 
They show me evidences that data was typed correctly: For example, one invoice 
that is fully created and printed, after a while is not found in the database 
and information is loosed.
 

 I thought that could be some issue related to Sweep interval and Forced writes 
but the issue persists. It is not constant and I have been unable to reproduce 
it.
 

 Have checked the database with gfix dont finding errors.
 

 I susspect that it is related  to some kind of data cache that for any unkown 
reason finally doesn't post changes to disk.
 

 Have anyone had this situation?
 Is it posible that it is related to a Windows version?
 

 Sincerely dont know how to work arround this.
 

 Any help will be appreciated.
 

 Regards
 

 Hernando.
