Enterprise Manager

I have an issue with an Oracle database (10.2.0.4) I'm managing where under Availability in the Enterprise Manager it reports "Agent Unreachable" continuously. I've been through the various posts on this forum and other I've found but I've not been able to resolve the issue.

Here is the output of various logfile and command which might be of use:

[oracle@tspr05 log]$ emctl status agent

I can access the URL and get back the message "Congratulations, EMAgent is working!" when I connect.

The emagent.log file shows no errors however I get the following messages repeatedly in the emagent.trc file:

Again if I try and access the URL for the upload server it works and I get back "Http Receiver Servlet active!"


I'm not sure where else to look so if anyone can be of any assistance I'd be very grateful.
