1. Run firebird server as application:
firebird -a
2. Start user trace session
fbsvcmgr localhost:service_mgr action_trace_start trc_cfg fbtrace1.conf
3. Shutdown firebird server using menu of tray icon
Trace output wiil be like below:
-----------------------
Trace session ID 1 started
2015-08-12T15:49:29.0270 (5420:000000000B6D2790) TRACE_INIT
SESSION_1
Error reading data from the connection.
-----------------------
Last line clearly shows that firebird crashed. Tray icon leave at tray and will disappear if one try to activate it.
