Do not use shared memory

Remove the iqwmem switch from the params.cfg file for the IQ server when you are *not* on Solaris or HP-UX. Example:

-iqwmem 500

See for more information.

Make sure that asynchronous I/O is enabled

Asynchronous I/O must be enabled on the server where the IQ instance is running.

On RedHat / Centos / Fedora

yum install libaio

On Ubuntu:

apt-get install libaio1

Before you try again

In both cases you need to reboot the IQ instance to activate the changed configuration
