Both my main Nagiosxi and Backup xi server started doing this immediately after the 2012R1.1 Upgrade:
I rebooted the Backup server but that made no difference. Help!
It appears search hangs too... really anything with any kind of details page is hanging.xi 2012R1.1 Service Detail and Host Detail pages hang

Did you try holding the "Shift" key + Right click->Reload in your browser?

Just tried that, no change. I also tried a different web browser, same thing.
The legacy Nagios (not xi) interface is working as well as the Nagios Mobile interface. Weird.

Run the following command and show the output:
Code: Select all
tail /var/log/httpd/error_log

Re: xi 2012R1.1 Service Detail and Host Detail pages hang
I think this is some sort of local caching issue on my end.
I just browsed the detail page from my phone (Android) browser, and it worked.
edit: Confirmed. I did a manual cache clear in Chrome and that resolved it.
Sorry to have bothered you
