application:stop hangs

[Chandrashekhar Mullaparthi]

Hi,
 
I need help finding out why my application:stop hangs. 
I have a supervisor(one_for_one) which has:
 
5 vanilla gen_servers, 
    {permanent, 2000, worker}
 
10 workers spawned using proc_lib:spawn by one of the above gen_server. Do
not trap exits
    {transient, brutal_kill, worker}
 
2 gen_servers which trap_exits but also shutdown when they receive a
{'EXIT', Parent, shutdown} message
    {permanent, 2000, worker}
 
1 supervisor(simple_one_for_one) which supervises two other vanilla
gen_servers
    {permanent, 5000, supervisor}. Childspec is {transient, 2000, worker}
 
How do I track down the rogue process(es)?
 
tia,
Chandru
