How to Enable Core Dumps on SMG

1) Log into Putty or go to console screen of SMG server. Switch to root user by typing: sudo su

Type the password for the gwava user when prompted.

2) Create a dumps directory by typing: mkdir -p /var/dumps

3) Edit the /etc/rc.local file by typing: vim /etc/rc.local

Add the following lines above the gwava7 start command, see example (hit the insert button or the letter i, once in the file):

ulimit -n 65536
ulimit -c unlimited

sysctl -w kernel.core_pattern=/var/dumps/core.%e.%p.%t 

    Hit escape, then type :wq (this will save and exit the file. If stuck hit esc, then type :q! to exit without saving changes)

4) Stop SMG by typing: /etc/init.d/gwava7 stop

5) Make sure SMG is down by typing: /etc/init.d/gwava7/status

6) If a module is still running, wait a minute and do another status check. If some are still running find the PID for that module and kill it. To find the PID type: ps ax | grep gwava If a module needs to be killed type: kill -9 <PID>

7)  Now type each of the lines added above at the prompt. Otherwise, the server will need to be rebooted in order for the changes to take affect. Type each one separately:

Type: ulimit -c unlimited

Type: ulimit -n 65536

Type: sysctl -w kernel.core_pattern=/var/dumps/core.%e.%p.%t

8) Start SMG back up by typing: /etc/init.d/gwava7 start
