Firebird 2.5.6 & 25.8 server crash
----------------------------------
Key: CORE-5980
URL: http://tracker.firebirdsql.org/browse/CORE-5980
Project: Firebird Core
Issue Type: Bug
Components: Engine
Affects Versions: 2.5.8, 2.5.6
Environment: Windows Server 2012 R2
Reporter: Svend Meyland Nicolaisen
Attachments: Capture.PNG
We have an application which creates a firebird database from scratch,
populating it with a large number of tables, views, indices, stored procedures
etc. On servers that runs on hardware that are slower than production systems
normally are, the Firebird server crashes every time our application tires to
create the database. The statement that apparently crashes the server does not
crash the server when executed at any other time, so I am thinking it is a
result of some or all of the previous statements. Also - the server does not
crash (every time - I might have seen it once or twice) on faster systems,
which makes me think that is some sort of race condition in the server.
I have tried to connect WinDbg to the server, and an access violation
repeatedly begins to occur several statements before the fatal statement. All
of the statements (except for the fatal one) however executes as expected.
Several access violations occur before the server crashes (too many to count).
I have attached a screen dump of the call stack when one of the access
violations occur.
I am experiencing the problem with Firebird 64 bit server version 2.5.6 and
2.5.8 running as SuperServer on Windows. I haven't tested with other versions
of Firebird.
Our software works perfectly on all our production systems, but these crashes
worries me a bit, as it indicates that there is some problem that could appear
any time at any system.
I don't know if this is a problem that the Firebird developer group will look
into, or if the 2.5 version is permanently closed. If it is, I will gladly help
with further information.
Kind regards,
Svend
