【ID 1379200.1】中对这个错误的描述：

What does this message mean ?

The message indicates that we failed to spawn a new process at the Operating System level to serve the request. There are various causes for this issue.

This typically occurs when there is a shortage or misconfiguration in Operating System Resources, and thereby the problem should be investigated from an OS perspective. However there are a few causes related to the Oracle Database as well.
