-------------------------------------------------------------
Key: CORE-4558
URL: http://tracker.firebirdsql.org/browse/CORE-4558
Project: Firebird Core
Issue Type: Bug
Components: Engine
Affects Versions: 2.5.3
Environment: OS : Debian 6 (x86), Debian 7 (x86), OpenSUSE 13.1( amd64
), Ubuntu 14.04 (amd64)
HW: intel CPUs ( i5 , i7, xeon )
Reporter: Sergey Maslikov
Firebird 2.5.3 Super server ( 2.5.2 ) dies when client that use embedded SQL
cursor disconnected abnormally.
SS calls function fb_utils::logAndDiewhen you terminate a client while fetching
data from a cursor;
The Server receives SIGHUP and dies.
I`ve tried to reproduce the same situation using IBPP library but I didn`t
succeed.
