Kadmin max connections

[Digant C Kasundra]

Hello list,

Does anyone know how many incoming connections/active connections
kadmind can handle?  I'm stress testing password changes and if I hit
the kadmind server with more than 20 simultaneous password changes, I
get "kadmin: GSS-API (or Kerberos) error while initializing kadmin
interface" errors.

Have I hit an upper limit here?  Is there a way to accept more
connections?  What are my options and/or errors and/or
misunderstandings?
