Running an execNative Command in the Background Might Take More Than Ten Minutes to Start Execution on IBM AIX Platforms (6315401)

When executing an execNative step with the background option specified, the command might take more than ten minutes to start instead of starting immediately.

This issue occurs on IBM AIX systems that have the number of open file descriptors set to a value in excess of a million or unlimited. Unlimited equates to approximately two billion. You can determine the current soft limit on the maximum number of open file descriptors by executing the ulimit -n command.

Workaround: Set the value of the nofiles parameter to 2000 in the /etc/security/limits file for either the user that is running the agent process or all users. Following a reboot, this value persists and affects all users on the machine.

The value of the nofiles parameter must not exceed 100,000.

For more information about the /etc/security/limits file, perform the following steps:

1. Go to the IBM AIX Information Center at http://publib.boulder.ibm.com/infocenter/pseries/index.jsp.

2. Type limits file in the Search text field.

3. Click the GO button.

4. Click the limits File link in the search results.
