We are trying to open web console for the web reporter but getting the above error. Actually we have restarted the server and also rebooted the server but still no changes. actually the installation folder is having few MB of free space left. I could see that both the web reporter services are running.
Please let me know how to come out of the situation.
Likely something crashed it, or if/when you tried to restart it, there was a port conflict.
Stop/Kill the service, which is java.exe running under the SYSTEM account.
Then try starting it again.
