Vlad Khorsun reopened CORE-3969:
--------------------------------
Fix was Windows only and it is wrong. Reopen to complete fix.
> Memory leak when doing a lot of iterations FBSVCMGR with action_trace_start,
> _list and _stop
> --------------------------------------------------------------------------------------------
>
> Key: CORE-3969
> URL: http://tracker.firebirdsql.org/browse/CORE-3969
> Project: Firebird Core
> Issue Type: Bug
> Components: SVCMGR
> Affects Versions: 2.5.0, 2.5.1, 2.5.2
> Reporter: Pavel Zotov
> Assignee: Vlad Khorsun
> Fix For: 2.5.3
>
> Attachments: pslist_m.zip
>
>
> I run infinite loop with the following actions:
> 1) FBSVCMGR action_trace_start
> 2) connect to .fdb via ISQL and make a simplest query, e.g.: select
> current_connection from rdb$database; quit;
> 3) FBSVCMGR action_trace_list (obtain the ID of active trace sesssion)
> 4) FBSVCMGR action_trace_stop
> Under such circumstances memory leak of process fb_inet_server (tested on SC)
> occurs.
> The following batch file illustrate the problem (some 3rd part utilities need
> for this test: mtee.exe for duplicating output and psList by SysInternals to
> output memory consumprion by processes):
> @echo off
> cls
> @rem file = 'trc_toggle.bat'
> @rem restart FB for each trace session number will be always 1
> @rem net stop "Firebird Server - fb25_3050"
> @rem net start "Firebird Server - fb25_3050"
> pslist -m | findstr /i /c:"name" | mtee /t pslist_m.log
> pslist -m | findstr /i /c:"fb_inet_server" | mtee /t /+ pslist_m.log
> set inp=.\tmp_sql.tmp
> set out=.\tmp_log.tmp
> set i=1
> :beg
> if exist %inp% del %inp%
> if exist %out% del %out%
> echo select current_connection,current_timestamp from rdb$database;>>%inp%
> @rem echo out nul; select * from rdb$fields,rdb$fields; out;>>%inp%
> echo quit;>>%inp%
> @echo off
> @echo -----------------------
> @echo Start of iter # %i%.
> @echo on
> start /min %FIREBIRD%\bin\fbsvcmgr localhost:service_mgr action_trace_start

> %trc_id% 1>tmp_trace_stop.tmp 2>&1
> @rem check that no trace sessions still alive:
> %FIREBIRD%\bin\fbsvcmgr localhost:service_mgr action_trace_list
> @echo off
> @echo End of iter # %i%.
> pslist -m | findstr /i /c:"fb_inet_server" | mtee /t /+ pslist_m.log
> ping -n 2 127.0.0.1 >nul

> set /a i=i+1
> goto beg
> The cumulative log of this batch (results of psList -m) is in attach.
