Hard Disk Defraggers
Several people have reported complete system crashes (blue screen of death, reboot) on Windows NT when running a hard disk de-fragmenter while the Lyris List Manager is busy.
One person had their defragmenting utility use up all available system memory. Thus, making it impossible to shut the server down or even terminate the task.
For this reason, we do not recommend defragmenting your hard disk while the Lyris List Manager server is running.
