I saw this article in the manual
http://docs.splunk.com/Documentation/Splunk/6.2.5/Installation/InstallonLinux#Default_shell

Default shell
Splunk Enterprise assumes you are using the bash shell.
Using the dash shell can result in zombie processes.

I am using ubuntu or debian, using dash as default, what would be the consequences ?

The problem is that on "dash" shell, the processes created by splunk for scripted inputs will not be terminated when you restart splunk, or when the new script run starts.

By example with the AWS app, you may see many processes like

ps -aux | grep splunk
python /opt/splunk/etc/apps/Splunk_TA_aws/bin/aws_cloudwatch.py   

that will be running for a long time (even prior to the last splunk restart)
and ultimately exhaust resources on the box.

This does not happen since I run splunk under a bash shell.
Be careful on debian like OS (debian, and ubunbu)
