Problems with Jetspeed UserBrowser

[Kunchakarra Prasad <Pr...@arbitron.com>]

We are encountering a problem related to UserBrowser when the number of
users in the User Directory are large. Right now, when we loaded 1000 users
into the LDAP directory the following error is displayed on the browser:
 
Error rendering Velocity template: /portlets/html/user-browser
..vm: Unable to find resource '/portlets/html/user-browser.vm'
 
In addition, the following errors show up in velocity.log
 
velocity.log:2003-03-26 16:00:47,411 - ResourceManager : found

We are using jetspeed1.4b3 version with IPlanet Directory Server 5.1 as
Jetspeed User Repository. It seems to me that something is going wrong when
the number of users exceed a certain limit/timeout. Is there any
configurable parameter that governs this kind of limit? If not, is this a
bug? If so, is there any this bug is fixable.
 
We did not any see any problems when the number of users were around 900. 
 
Any hints in solving this problem are greatly appreciated.
