What can cause the initial installation to fail with random errors or crashes?
First, check to see if the system has been properly tuned according to the documentation. For example, if channelcnt is not set to 4096, you may experience “file not found” errors or random crashes. Please review the documentation carefully. Pay close attention to the privileges and quotas required for the account that installs WebLogic Server. Privileges are required to install WebLogic Server, but are not required to run the server.
