When trying to access the groups page (http://servername/redmine/groups), the page would take about a minute to load. Thereafter we would receive the following error:

Proxy Error

The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /redmine/groups.

Reason: Error reading from remote server

We increased the keep-alive/timeout values in Apache (we assumed this was related to timeouts occurring because of the considerable amount of groups we have). Now we receive a different error:

Internal error

An error occurred on the page you were trying to access.
If you continue to experience problems please contact your Redmine administrator for assistance.

If you are the Redmine administrator, check your log files for details about the error.


I've attached an excerpt from our error log.

Please note we have a considerable number of groups in Redmine (over 30,000). Is the page failing to load because of an application or database limitation?

It is Apache log, not Redmine.

#2 Updated by Jonathan Heng about 8 years ago

Thanks for the correction. Yes, this is an apache log. Does anyone know if this is an Apache limitation? Or is it a Redmine limitation?

#3 Updated by Toshi MARUYAMA about 8 years ago

See Redmine log.

If you have many groups, this problem may be fixed by r13149 (included in forthcoming 2.6.0), see #16905. Before the fix, all users from all groups were loaded when displaying the group list.
