Random outages of OAM-protected applications that have been upgraded to WebGate are occurring.

HTTP-500 Internal Server error is displayed in the user's browser. The Apache server console and WebGate oblog.log show Oblix_OBWebGate_AuthnAndAuthz error message repeated, as shown in the example below.

[Mon Jun 23 10:24:39 2008] [error] [client] Oblix_OBWebGate_AuthnAndAuthz: Error: /oracle/product/oam/access/oblix/config/oblog_config_wg.xml - Unable to read log
configuration file., referer:

Restarting the Apache WebGate resolves the issue until next occurrence.

The problem only reproduces when Apache is using worker MPM on a multi-CPU server.
