i used this script :

#!/bin/bash
COUNTER=0
ulimit -c unlimited
while :
do
   valgrind --tool=memcheck --leak-check=full --show-reachable=yes --log-file=valgrind-$COUNTER.log ./mangosd #should be console disabled;)
       mv valgrind.core* valgrind-core.$COUNTER #if system not add .proccess_id to dumps for sure move it to keep it
           COUNTER=$(($COUNTER+1))
           done

i am trying to get mangos stable again, so any help would be nice, i am not experienced with valgrind, so tell me if i am doing this right, or what to do,. also have problems, mangos really lags with vlagrind(60online and 3-10sec lag), it use only 1-2core (have 8) i used also derex mtmaps patch with this test, if anyone know how to use valgrind on all cores ...or some special settings, what DEVS need

thx, and tell if this logs are need .. or how to find, that annoig freez in mangos :(

also tryied some gdb : theres loop somewhere:(

cause i didnt managed to work purify on linux, i did some logs with valgrind (i am still looking for some DEV witch can join to mine server and install purify, PM pls)

NEW Vlagrind logs, mangos rev 7158 + sd2 857(modified some c++ scripts sorry)

mangos is almost clean, without derex mtmaps, only some minor changes at player plevel accounts+ player titles:)

here are two valgrind logs, one is only mangos startup with full debug mode, without optimization, second is debug, with optimization, and cca 2hours gameplay, i also reproduced crash described here:

http://getmangos.eu/community/showthread.php?p=56944#post56944

here are the valgrind logs:

here are bt from core dumps generated by gdb/valgrind

http://pastebin.com/m73b92b7e crash

http://pastebin.com/m145027f5 ctrl+c ?:D (i am not sure )

hope it helps : )

There are a LOT of serious SD2 errors! They could be causing some of the core bugs/crashes/freezes but it's impossible to fix them if you don't use clean SD2.

Did you reproduce it while running under valgrind ? The first log ends with a freeze and the second one seems to be shut down/terminated.

i need to get working purify, its really slow with valgrind ,..

i will do some valgrind for clean sd2 too (i modified only BT,sunwell,ZA)

and first log should be with crash / freez :

i did what i described here, and got crash or freez not sure

http://getmangos.eu/community/showthread.php?p=56944#post56944

i posted bt from valgrind.core dump + valgrind.log . think its freez cause i had setting 2mins for freeze detector. i am using script in first post, if u could modify it , to generate right files, or what should i do in moment of freez, i can post aditional logs, but need to know how... mine script auto generate core dump+ log file, i just du bt full on that core file

Been a long time since anyone made a valgrind log of the server .. looks like there's lots of info to go over :).

i did another valgrind,

==8114== LEAK SUMMARY:

==8114== definitely lost: 1,467,961 bytes in 135,580 blocks.

==8114== indirectly lost: 176,135 bytes in 2,760 blocks.

==8114== possibly lost: 15,705,824 bytes in 162,928 blocks.

==8114== still reachable: 1,871,554,842 bytes in 2,138,667 blocks.

==8114== suppressed: 0 bytes in 0 blocks.

but i have still problem, how to run valgrind on all cores? it really lags, i cant try to freez it(more then 100ppl, 5-30seclag), so we cant find wheres loop, is there another tools, how to find freez crash etc ? .

or mine script is it all what u need ?

i need info what should i do, i can give access to server if need..

http://filebeam.com/0409c4cd70d87de8be64eb9c8c4a79ff

i really want have mangos stable again (note i have some changes in core, but they definately not relatd to freez, tested without)

how to run valgrind on all cores?
The main thing to point out is that although Valgrind works with the built-in threads system (eg. NPTL or LinuxThreads), it serialises execution so that only one thread is running at a time.

This approach avoids the horrible implementation problems of implementing a truly multiprocessor version of Valgrind, but it does mean that threaded apps run only on one CPU, even if you have a multiprocessor machine.

So multicore support is NYI in valgrind :o

If by "that" you mean the last freeze you posted in the crash report thread then it's fixed. Could you please post which revision you made those logs with ?

:( i am not sure , it was like 7094 or 7090 ,

i will make new logs of valgrind/purify(hope i get them to work) soon with clean mangos, (think today) and will post revs number also

mine was ending with WorldSocket::handle_input_header: client sent mailformed packet size = 16831 , cmd = 1717468147 not sure what does this msg mean , some hacks think.

will see hows new revs stays up:)

Since you're using clean mangos, please also use clean SD2. I've gotten complaints that some of the errors that show up in your logs are not present in SD2.

will do, but i cant get purify working on debian:( need help with that, if its possible i will give u access on server and u can install it, if ye, send me pm, we can talk about it.. (derex was ones on our server but i dont have access to devs irc, so cant talk to him, didnt see him on normal irc)

Im been having real issues on windows too, so ill use purify for windows and im also debugging so ill post all the info i get in a .zip later on tonight :)
That would be great, just remember that in order to use purify on windows you need to:

- switch to Debug mode

- remove #include <vld.h> from MemoryLeaks.h

- for EACH project (where you have linker options), including SD2!, set the following:

Linker->Advanced->Fixed Base Address->Generate Relocation Seciont (/Fixed:No)

Linker->General->Enable Incremental Linking -> No (/incremental:no)

- full rebuild everything

Much more people could help you if you would just report what error/problem you are having, in detail.

i tryied to intall it,

after log to putty i have this err.

   IBM recommends you run rs_install on a machine running one of
   these operating systems.

     Rational PurifyPlus for Linux (Evaluation) - Enter Install Location

   Enter the location to install IBM Rational products.
   This will be referred to as the 'Rational' directory.
   In 'Rational' directory, rs_install will create a releases
   directory to keep all of the products by name and version.

   For example, in 'Rational'/releases, this install will
   create a 'PurifyPlus.7.0.0.0-012.Eval' directory to install
   Rational PurifyPlus for Linux (Evaluation) 7.0.0.0-012.Eval.

   The 'Rational' directory must be accessible from
   every machine where you plan to run these IBM Rational products.
   The 'Rational' directory path must be identical on each machine.
   Thus, an automount path like /tmp_mnt/rational should not be used
   because you cannot access this directory from every machine.

   Checking for 'Rational' directories..  One found.

   Enter 'Rational' directory: [/releases]

   Running LAP Tool:
/opt/_purify/PurifyPlus.7.0.0.0-012.Eval.Linux_x64/extras/LAP/jre150.i386_linux2/jre/bin/java -classpath extras/LAP/lib/lapapp.jar:extras/LAP/lib/i18n.jar com.ibm.lex.lapapp.LAP -l extras/LAP/LA_files -text_only -s /releases/releases/PurifyPlus.7.0.0.0-012.Eval

   Will look for a different version of java and try again.

   JRE failed to run.  Cannot run LAP Tool.

Thanks for the help with that Wyk3d. Been really busy last night and will be tonight but ill sort it out ASAP :)

If it helps here's a crash log from last night. I managed to stop the bad lag spikes and now its just a little. Then a big lag spike before the server crashes and restarts. http://paste2.org/p/134430

This is what i tried:

Visibility.GroupMode = 0

Visibility.Distance.Creature = 45

Visibility.Distance.Player = 45

Visibility.Distance.Object = 45

Visibility.Distance.InFlight = 45

Visibility.Distance.Grey.Unit = 1

Visibility.Distance.Grey.Object = 10

Instead of the default 66
