------------------------------------------------------------------------------
Key: CORE-5294
URL: http://tracker.firebirdsql.org/browse/CORE-5294
Project: Firebird Core
Issue Type: Bug
Affects Versions: 3.0.0, 4.0 Initial
Reporter: Pavel Zotov
Attachments: memory-leak-when-use-show-grants-in-FB_301-or-FB_400.7z
1) Run ProcessExplorer or similar tool for monitoring process resources
2) create empty database, add it to databases.conf (aliases.conf for 2.5)
3) Run following .sql script several times:
===
set wng off;
set list on;
set echo on;
connect 'localhost:e25' user sysdba password 'masterke';
show grants;
quit;
===
Sample of batch for this ('fbc' variable stored path to different FB binaries
on the same host ):
===
@echo off
set fbc=C:\MIX\firebird\fb25sS\bin
::set fbc=C:\MIX\firebird\fb25\bin
::set fbc=C:\MIX\firebird\fb30
::set fbc=C:\MIX\firebird\fb30sC
::set fbc=C:\MIX\firebird\fb40
::set fbc=C:\MIX\firebird\fb40sc
for /l %%i in (1,1,10) do (
echo %%i
%fbc%\isql -q -i memotrouble.sql 1>memotrouble.log 2>&1
)
===
On WI-T4.0.0.267 and WI-V3.0.1.32542 you will find noticable memory leak for
FB process (I've tested bothSS and SC).
No such trouble on WI-V2.5.6.27017 SC or SS.
Please see screenshots in attached .7z file.
