Subject Re: deadlock + "gds software consistency check" problem
Author derryck.welas
Hi mbanaouas,

1e, When faced with "internal gds software consistency check" always check your hardware(RAM/DISK).
In fact if the machine is critical do not accept any "Error" messages
in the OS system error log !

2e, check firebird's "TempDirectories =" the place this looks at should have enough space !


>Is there any way to localize the statement producing this deadlock ?

difficult, but if the statement is actually still running you can use
the monitor tables:


example:

SELECT
STMT.MON$STATEMENT_ID,
att.MON$SERVER_PID,
att.MON$ATTACHMENT_ID,
STATS.MON$PAGE_FETCHES,
STMT.MON$TIMESTAMP,
1000*(CURRENT_TIMESTAMP-STMT.MON$TIMESTAMP) AS SECS,
STMT.MON$SQL_TEXT
FROM MON$ATTACHMENTS ATT
JOIN MON$STATEMENTS STMT ON ATT.MON$ATTACHMENT_ID = STMT.MON$ATTACHMENT_ID
JOIN MON$IO_STATS STATS ON STMT.MON$STAT_ID= STATS.MON$STAT_ID
WHERE ATT.MON$ATTACHMENT_ID <> CURRENT_CONNECTION
AND STMT.MON$STATE = 1
--AND STMT.MON$SQL_TEXT<> ''
