CentOS 6 x64 VM (clean install) on vsphere 5.0 Update 2 (1vCPU and 4GB RAM).
This morning we've upgraded our Nagios XI 2012v2.3 to v2.7. After the upgrade the page "Scheduled down time" isn't available. Screen remains blank.
In the apache errorlog this error occurs:
[Mon Jan 13 10:00:54 2014] [error] [client 145.32.229.244] PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 36885192 bytes) in /usr/local/nagiosxi/html/includes/components/nagioscore/coreuiproxy.inc.php on line 157, referer: http://ssc-nagios/nagiosxi/
Update: Our test server doesn't have the problem. However, there are only 3 hosts in there. The production server has 281 hosts (+/- 1000 service checks).

We've removed some recurring downtime for a servicegroup so that or status.dat could shrink from 36MB to 11MB. We've changed the timeperiod for that service. Now the scheduled downtime webpage is available.
However, the recurring downtime setting for a servicegroup that I removed is still present in this screen.
It looks like we found the root of the problem. The status.dat file was 36MB and this file is used to build the screen.
We've removed the scheduled downtime entries for a servicegroup and our file is now 1,8MB.
I've seen this probleem before on the forum but can't seem to find it.
When a downtime is scheduled on a servicegroup not 1 but a lot of (unnecessary duplicate) comments are being made for that service. That service runs on a lot of hosts so service * comments * hosts = large status.dat
