If you use Classic, only one instance would crash, while others would keep running. In both cases, Firebird server is available for subsequent connections, so this may trick you into thinking that server did not crash. Do you find this FAQ incorrect or incomplete?

threaded view ♦ ♦ | Report Content as Inappropriate ♦ ♦ Error reading data from connection. Just recently we have been experiencing http://firebird.1100200.n4.nabble.com/Error-reading-data-from-connection-td2716870.html a lot of our firebird installations generating errors of type 'Error https://www.experts-exchange.com/questions/28318284/Firebird-connection-timeout.html reading data from the connection.'.Our Firebird installations are of the 'Classic' type andhave usedversion 1.5.2 for the past few years.Our .Net based softwareconnectswith the FirebirdSql.Data.Firebird dll (version 1.0.1241.28320). To dateour installations have caused very few incidents of the above error. In recent months the error reading frequency of these error has grown considerably and is now a serious concern for us. The errors are sourced to mainly the FirebirdSql.Data.Firebird.FbResultset.Fetch() call. While the FirebirdFaq site states that this error is: a) someone rebooted or restarted the serverb) Firebird server crashed this contradicts the fact that other PC's that are also connected error reading data to the sameServer and not generating these errors. Some PC's seem to experience these problemsmore frequently than others connected to same server. Furthermore, while the Fetch() is the main source of these errors, this error is also (to a lesser extent) sourced by the calls FirebirdSql.Data.Firebird.FbConnection.Close()FirebirdSql.Data.Firebird.FbStatement.DropStatement(). Is there a reason why we should expect the Fetch( ) call to be the main source of these errors? Is this error an issue with Firebird itself? We are under a lot of pressure to resolve this issue, and we'd appreciate any help that anyone can give us. Regards, Niall Naughton Software Developer, Merit Solutions Ltd.

Solved Firebird connection timeout Posted on 2013-12-14 Delphi Databases 1 Verified Solution 11 Comments 2,098 Views Last Modified: 2013-12-24 I have an application that accesses a Firebird database managed by a remote Firebird server. If there is not activity between the application and the database for a given time (I didn't test for how long it is), then if the application starts some work with the connected firebird server, it gets : "Unable to complete network request to host "....". Error reading data from the connection. An existing connection has been closed by the host" (last phrase I translated from french) I understand that very well but I want to fix it. In my code, each time I start some SQL activity, I check if the Connected property of the TIBDatabase is true and if not, I set it to true. The problem here is that the application see it as true but it is practically not as the host has stopped it ! So my question, what is the best code I can write to "reopen" the connection IF AND ONLY IF IT has been close by the host Thanks 0 Question by:LeTay Facebook Twitter LinkedIn Google LVL 36 Active 1 day ago Best Solution byGeert Gruwez this is a firewall problem > when no activity occurs on a connection, it gets severed by the firewall they will deny it at first due to ignorance > it usually takes a lot of negotation to solve this Go to Solution 11 Comments LVL 19 Overall: Level 19 Databases 18 Delphi 5 Message Expert Comment by:NickUpson2013-12-15 your problem is that the application doesn't know the connection has gone down until it tries to use it you need to do a query to t
