Create Crash Dump

[Kuroyama]

Hello everyone, it's me again /sob

Need a little help bout creating a crash dump.

I did follow this guides:

https://herc.ws/board/topic/2930-emergency-map-server-crash/

https://herc.ws/board/topic/7566-map-server-crash-how-to-get-dump-or-error-log/#comment-45609

https://herc.ws/wiki/GDB

https://herc.ws/board/topic/14678-linux-map-server-crash-on-autotrade/#comment-82120

./configure --enable-debug=gdb

ulimit -c unlimited

or even this

make clean
./configure --enable-sanitize --enable-debug=gdb --enable-manager=nomake




still no dump file. Looked already in var/crash and even on the trunk.

Please help.

you show only configure command. what about make? you run it after configure?

you used sanitize flags, if your compiler support them?

if compiler not support it, then it will be skipped.

but if sanitize flags supported by compiler, you don't need crash dump. on issue server will show message where it crashed by self.

 

[Kuroyama]

you show only configure command. what about make? you run it after configure?

gdb map-server

run

you mean sir @4144?

I'm not sure if i'm doing right but I just did follow everything, from wiki to reference thread.

I just badly needed the crash dump file like the dbghelp plugin for windows.

 

[4144]

make clean
./configure --enable-sanitize --enable-debug=gdb --enable-manager=no
make


i this commands

 

[Kuroyama]

make clean
./configure --enable-sanitize --enable-debug=gdb --enable-manager=no
make

make clean
./configure --enable-sanitize --enable-debug=gdb --enable-manager=no
make


i this commands

yes sir I did. it compiles smooth and no errors or something.

is there anything that I left out?

my map-server crash twice but I still can't find the dump file,

I usually close putty so can't monitor it real time that's why I need the dump file.

 

[4144]

i hope you using screen or tmux?

because if not and you close your ssh connection, this is wrong. you cant see how your server working and cant control it.

at first check is your compiler support sanitizers. run this command and show output from it:

./configure --enable-sanitize --enable-debug=gdb --enable-manager=no|grep sanitize

oh here your configure failed, this mean anything what you add to configure is not used

try configure like this:

./configure --enable-debug=gdb


and show output of it, at least some last lines

Here it is sir @4144.

ok, by default configure works. but sanitizers is not.

then if you want build your server need run this commands:

make clean
./configure --enable-debug=gdb
make




if you have issues with crash dump creation,

run map server from gdb like this:

gdb ./map-server


and run command

run


inside gdb

if you using screen you can reconnect after and see how your server crashed.

after crash in gdb run

bt


or

bt all

Will update you sir very soon after I encounter the crash again.

Still no crash dump at all. @4144

you can show on your screenshot more info?

from lines what you show server not crashed at all.
