Memory leak in FB 3.0 while doing reconnects with valid user/password
---------------------------------------------------------------------
Key: CORE-4683
URL: http://tracker.firebirdsql.org/browse/CORE-4683
Project: Firebird Core
Issue Type: Bug
Reporter: Pavel Zotov
Attachments: fb-memo-watch-while-reconnects.zip
FB: WI-T3.0.0.31603 (both client & server)
OS: Windows XP SP3
Aux. utilities being used in this test:
1) psKill (from SysInternals package)
2) mtee (Stream Splitter, can be taken here: http://www.commandline.co.uk/mtee/
)
Main batch:
=========
@echo off
@cls
@rem makes infinite loop with CONNECT & DISCONNECT
setlocal enabledelayedexpansion enableextensions
set fbc=C:\1INSTALL\FB30SNAP
set host=localhost
set port=3333
set dbnm=oltp30
set err=connect.err
:m1
echo select current_transaction from rdb$database;quit; | %fbc%\isql
%host%/%port%:%dbnm% -nod -n 1>nul 2>>%err%
goto m1
exit
Batch for watching + logging memory:
==============
@echo off
setlocal enabledelayedexpansion enableextensions
cls
set log=memowatch.log
set intv=5
del %log% 2>nul
set /a intv=%intv%+1
pslist -m 2>nul | findstr /i /c:"name" | mtee /t /+ %log%
:m1
pslist -m 2>nul | findstr /i /c:"firebird" | mtee /t /+ %log%
ping -n %intv% 127.0.0.1>nul
goto m1
:end
Window-1: start watching batch
Window-2: start main batch.
After short time one may see in the log or on concole of window-1 that memory
consumption grows for 'firebird' process.
See in attach:
1) memowatch.log
2) screenshot from PE
