Problem
In a distributed setup, you encounter the following problems on the central site.:
The GUI on the central site randomly becomes very slow, and the "liveproxyd.log" gets filled with hundreds of these entries:

2021-09-30 16:24:45,502 [40] [cmk.liveproxyd.(5252).Site(<remote_site_name>).Client(81)] Reading request from client took longer than 5s
Traceback (most recent call last):

raise ClientRequestTimeoutException(
cmk.cee.liveproxy.Client.ClientRequestTimeoutException: Reading request from client took longer than 5s |

Reading requests from client took longer than 5s |
This is caused by the GUI, which establishes a connection with the Liveproxyd but then does not send any query. This could indicate an overload of either the GUI or Liveproxyd.

If the werk mentioned above is the cause, this workaround might also help before installing p9: - Remove all Host/Service Statistics Snapins in all dashboards
- Save them
- Re-add them
- Then reload all dashboards in the browser.

If this does not work, please open a ticket and add the ~/var/log/apache/access_log of some of the affected sites, which might show many entries like
"ajax_figure_dashlet_data"
