Anakid as told before I have seen all this and installed accordingly but after the map server crashed I used this command

gdb map-server_sql map-server_sql.core

 

But got this error

[root@server trunk]# gdb map-server_sql map-server_sql.core

Hi Vengeance,

 

Within the SSH terminal, you type the following commands...

 

cd /root/Desktop/trunk
gdb ./map-server_sql
run

 

Then the process of the map-server_sql will start running. After it receives the crash signal, you would need to type;

 

bt full

 

Finally, you get the debug report that you need.

Thank you very much Asura.. I have done as you said.. Now let me wait when the map server crashes (hope it doesnt)

Asura tell me one thing.. My putty closes after a while so how will i be able to use the bt full command if the putty closes...??

Hi Vengeance,

 

Then perform everything in a screen session; so when the map-server crashes, you can just re-attach to that screen and perform 'bt full'.

screen
cd /location/to/trunk
gdb ./map-server_sql
run

Then you are safe to exit PuTTY with it running. Once the map server crashes, log back into PuTTY and find the current screen PID.

screen -ls

 

The ID is the # value; so then you want to re-attach to that screen by performing this command...

screen -x #
