Additional httpd.worker Processes Created Which Cause Problems with System Accessibility (Doc ID 2254160.1)

Last updated on JULY 20, 2024

Applies to:

Oracle Transportation Management - Version 6.4.1 and later
Information in this document applies to any platform.

Symptoms

On system startup typically there are three or four "httpd.worker" processes launched.

Doing a ps -ef | grep worker will show these among other non-OTM threads

This count is typically stable over time, but there is some activity that triggers growth to over 100 worker processes. When this occurs it makes the server unresponsive to User logins. Clients reporting this issue have noticed these additional processes may need to be manually "killed" before a normal restart returns the system to functioning state.

Changes

The OHS install was created on a NFS mount.
