The customer has installed OAM on Sun Solaris SPARC platform. OAM Server mode has been changed to Simple and WebGate agents have been registered in Simple mode.

The WebGates fail to initialise when a protected resource request is received by the WebGate webserver. The WebGate oblog.log shows messages similar to the following repeatedly:

2012/01/05@18:46:57.60776 26949 28 ACCESS_GATE FATAL 0x00001520 /ade/aime_ngamac_934556/ngamac/src/palantir/webgate2/src/apache2entry_web_gate.cpp:591 "Exception thrown during WebGate initialization"

The OAM 11g Server diagnostic log has the following entries:

The issue is not reproducible on Linux platform, it is specific to the OAM Server installations on SPARC Solaris.

The issue occurs with 10g WebGates, 11g WebGates and OAM Tester.
