[Exim] Exim Probs with solaris 2.7

Hello,

I tried to use exim-3.12 with solaris 2.7 with many virtual IP-Adresses and
found a strange behaviour. When I use 249 virtual IP-adresses everything is
fine. Is the number of virtual IP-Adresses greater than 249 exim ends with a
panic. A exim -d9 -bv rocholl@??? leads to:

Exim version 3.12 debug level 9 uid=0 gid=1
probably ndbm
Caller is an admin user
Caller is a trusted user
sender address = root@???
Verifying: uid=0 gid=1 euid=0 egid=1

original hostlist=mail.icsmedia.de options=byname
expanded hostlist="mail.icsmedia.de" options=byname
LOG: 0 PANIC DIE

Thanks for help

P.S. Here the content of my configure file:

primary_hostname = web.icsmedia.de
host_lookup = 0.0.0.0/0
end
remote_smtp:
  driver = smtp
local_delivery:
  driver = appendfile
  file = /var/mail/${local_part}
  delivery_date_add
  envelope_to_add
  return_path_add
address_pipe:
  driver = pipe
  return_output
address_file:
  driver = appendfile
  delivery_date_add
  envelope_to_add
  return_path_add
address_reply:
  driver = autoreply
end
system_aliases:
  driver = aliasfile
  file = /etc/aliases
  search_type = lsearch
  user = root
  file_transport = address_file
  pipe_transport = address_pipe
userforward:
  driver = forwardfile
  file = .forward
  no_verify
  no_expn
  check_ancestor
  file_transport = address_file
  pipe_transport = address_pipe
  reply_transport = address_reply
localuser:
  driver = localuser
  transport = local_delivery
end
lookuphost:
  driver = lookuphost
  transport = remote_smtp
literal:
  driver = ipliteral
  transport = remote_smtp
end
