Hello:
I have an application developped in Delphi that uses Firebird 2.1.4.18393 SuperServer.
The application is running well in many enterprises. But there is one place where there is a problem. They have a server with Windows and 4 client computers with Windows. They have been using the application since 2011 without problems. But since May 2015, almost every day it happens that many times Firebird service terminates unexpectedly. Sometimes it happens once in a day, sometimes twice or may be more.
It is not at regular times. Many times it happens at, for instance, 03:00am, when nobody is working and the only computer turned on is the server.
In the Windows event viewer, each time this happens, I see an event with the text "Firebird Server - DefaultInstance service terminated unexpectedly.".
In Firebird.log there are some messages that may be usefull. I copy some at the end of this message.
Till 10 days ago, the server had Windows Server 2003. Now they changed the server for a new one and installed Windows Server 2008 R2 64bits. They changed the server just trying to solve this problem, but the problem is still there. Every day Firebird service terminates many times.
Any idea of which may cause Firebird service termination?
Regards
Eduardo
