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.


The OHS install was created on a NFS mount.
