Correcting errors with kernel parameter values

If an installation fails because of incorrect kernel parameter values, confirm the values and restart the installation process.

Symptoms

Installation fails with one or more of the following error messages:

Unable to create a new process

Process number is too small

Out of memory

Stack overflow

Causes

Incorrect kernel parameter values.

The Out of memory error message is an indication that physical memory is insufficient.

For configurations that use IBM® DB2®, the optimum kernel parameters are suggested by the db2osconf utility, which is available after you install DB2.

Environment

This advice applies to Linux® and UNIX® operating systems.

Resolving the problem

The resolution to these error messages can typically be achieved by modifying the kernel parameters to meet the minimum requirements.
For all other configurations: Confirm that the computer meets the minimum kernel requirements and installation system requirements.
