Information in this document applies to any platform.
You have installed Oracle Application Server 10g (10.1.x.x.x) in two virtual machines (VMs) on the same physical host, using the same ports for Oracle Notification Service (ONS) and Oracle Process Manager and Notification (OPMN) in each VM.
Although you are using using different NIC host name and IP addresses for each virtual machine, the ports at the local host level conflict.
The opmn.exe process (or opmn in unix) creates an excessive number of handles or processes, and when the number of handles exceed 527 000, the product is unavailable to end users.
In unix this will appear as increasing memory utilisation by the OPMN process in a 'ps -ef' output. In Windows Task Manager the number of handles is seen to be increasing.
