There is a group that is used as a Deny group for 3644 composite groups. I can navigate to the folder with the group. But when I try to "open the group".... the browser "times out" at exactly 60 seconds.

I have stumbled into an odd thing in my prod instance.

There is a group that is used as a Deny group for 3644 composite groups. I can navigate to the folder with the group. But when I try to "open the group".... the browser "times out" at exactly 60 seconds.  NOTE:  I believe there are no members in the group.

Any ideas on how to "fix that"?
 
Yes this is MYSQL... but other such "deny groups" can be displayed... so.....)
 v 2.5.29
LOL.. uh.. yea....
select count from grouper_composites gc where right_factor ="ad5c55b21c184823bbefd140d99aa99e"
– 3644
 

So it tops this query.. 
select right_factor , count from grouper_composites gc group by right_factor ORDER by count DESC
Next one is 1,492
 
I can display the second one on the list.
 So the "fail point" is somewhere between 1492 and 3644 for my env. 
 
( Or there is something else wrong with that group. )
 
I really don't know what the UI is doing that would be "slower" because the group is used in composites during the display of the group.
 
The group does have some memberships.... 13
select * from grouper_memberships_v gmv where GROUP_ID ="ad5c55b21c184823bbefd140d99aa99e"
4 are "immediate" [other groups]  ( others are effective, all subjects from our "person" subject API )
 
Oh.. strike that... those are all Privileges.... ( LIST_TYPE= "access", LIST_NAME = [ "admins", "readers", "updaters" ] )No "members" list.
