Issue/Introduction

Executing the following ldap query:

basedn='tssadmingrp=acids,host=CALDAP,o=ABC CO

Attribute = $null

scope = subtree

While query is running, the CALDAP started task (server) is consuming to 50-100% of the CPU.  The query eventually times out and/or the user kills the task.  However, the CALDAP task appears to be continuing to process the query, with high CPU usage. 

Even though the task was killed, the task on the client side still active connections via /F CALDAP,COPS on the console.

IP=111.222.333.444:unknown
SRCH : SUB : tssadmingrp=ACIDS,host=CALDAP,o=ABC CO,c=USSRCH
IP=222.333.444.555:unknown
SRCH : SUB : tssadmingrp=ACIDS,host=CALDAP,o=ABC CO,c=USSRCH

The only way to close the connections is to cancel the CALDAP task and restart.
