Symptoms

Sometimes it takes close or over a second to load for one small gif 16x16.

This issue exists for both POA and PBA, overall control panel slowness is observed when loading static content.

UI server is deployed on NG webserver/cluster.

Cause

mod_hostinglimits Apache module is enabled on the UI server.

Resolution

mod_hostinglimits module is only required for FastCGI and not needed on UI, so it can be disabled in the corresponding configuration file:

# grep LoadModule /etc/httpd/conf.d/modhostinglimits.conf
#LoadModule hostinglimits_module /etc/httpd/modules/mod_hostinglimits.so
