I will to reproduce your issue, but I would like to know before how many custom fields do you have when the issue reproduces. Also, can you give it a try with the standard theme as well?

Thank you Marius for the replay. We have the issue with the standard theme also. Regarding the number of the custom fields, I didnt make really many tests to see at which number exactly the issue begin appearing, it may be a good test that I will perform shortly. By the way, the total number of custom fields is 1927.

I tried the mentioned test above ("the reducing of the number of custom fields to know at witch value the issue begin appearing"), and the result is that it is proportional, I mean:
- Reducing from 2000 to 1000 the issue still there (and the browser wait/abort message also appears) but the waiting time is now 30% approximatly.
- Reducing from 1000 to 500 the waiting time is about 10 seconds and now the message of browser is not appearing. Only the page freeze till passing the waiting time.
- With only 250 custome fields, there is no issue.

In case it helps, I attached 2 captures(both basic theme and our theme) of the appeareance of the page in the position where the custom fields stop loading.

Another option that may work (but I couldnt perform since I have no expirience in Ruby at all), is to implement a plugin (only in view level, no model creating neither migrations) is to split them in a 200 or 100 custom fields by page, having the pages index in the bottom of the page. The place to do that must be in "app/views/custom_fields/_index.html.erb", trying to avoid loading everything at once and stuck. Any idea about how to modify the file?

<table class="list custom_fields">
<thead><tr>
<th><%=l(:field_name)%></th>
<th><%=l(:field_field_format)%></th>
<th><%=l(:field_is_required)%></th>
<% if tab[:name] == 'IssueCustomField' >
<th><=l(:field_is_for_all)%></th>
<th><%=l(:label_used_by)%></th>
<% end >
<th></th>
</tr></thead>
<tbody>
< (@custom_fields_by_type[tab[:name]] || []).sort.each do |custom_field| ->
< back_url = custom_fields_path(:tab => tab[:name]) >
<tr>
<td class="name"><= link_to custom_field.name, edit_custom_field_path(custom_field) ></td>

<% end >
<td class="buttons">

<%= delete_link custom_field_path(custom_field) >
</td>
</tr>
< end %>
</tbody>
</table>

Yes, this is what we should do. Can you open a new feature request for this, please?

Anyway, if someone could averiguate the source of the issue and can help we appereciate a lot, since feature result may take a time.
Thank you for your effort and support.
