Troubleshooting Spinning/Rogue frmweb Processes Consuming 100% of CPU in 11gR2 or 12c Forms (Doc ID 2386477.1)

Last updated on NOVEMBER 15, 2021

Applies to:

Oracle Forms - Version 6.0.8 and later
Information in this document applies to any platform.


Spinning/rogue frmweb processes can have a serious impact on system performance since they can consume all CPU resources.

An frmweb process is associated with a user client session and should usually terminates immediately once a user closes their session. Depending upon what the user session was doing there may be some cleanup required when a session is closed so the frmweb may exist a few moments longer after session closure. If the frmweb session does not terminate within 15 minutes of the closed session, an internal mechanism should terminate it.

For various reasons - a product defect, unexpected session abort, application coding, operating system problem, etc. - an frmweb session disassociated from a user session may start "spinning" and eventually consume all of a system's CPU resources.

This note describes ways to prevent this as well as diagnose the cause of the issue.
