nagios upgrade from 4.0.7 to 4.2 interface very slow

Hi,
After upgrading from nagios 4.0.7 to Nagios 4.2 the web interface is extremely slow. Accessing e.g. the "problems" page takes around 60 seconds to load previously it was less than 5 seconds. The instance is large as it has 800 hosts and > 30k services.
Any ideas if this is normal behavior or how to debug further?
Chris

There is a known issue with 4.2.0 and the verify taking a long time, this could be related.
The maint branch on GitHub has a fix for it:
https://github.com/NagiosEnterprises/na ... tree/maint
4.2.1 is due to be released early September.
Are you seeing any errors in /var/log/httpd/*_log ?
What OS is Nagios running on?
Do you use http or https in your apache config?

Hi,
I did see that bug in my research but it doesn't fit as the verify command works fine for me.
I didn't check the http logs before rolling back.
Nagios is running on Ubuntu 14.04 LTS 64 bit
Only use http.

The apache logs would help out quite a bit as to see if it's looping on a timeout or what not.
I did see the maint branch working for another customer as well, which seems to be a similar issue to yours.

Could you test the maint branch in development, to see if this fixes your issue? Even if the -v works, it could still be related.
