[exim] Problem with exim

Hello Exim-Users,

i have the problem on my exim-server ( 4.82 ) that mails to remote_smtp
servers only work by the second connect. On the first connect i recive a
Bad file descriptor.

Regards

excerpt from my configuration:

begin routers

dnslookup:
  driver                      = dnslookup
  domains                     = ! +local_domains
  transport                   = remote_smtp
  ignore_target_hosts         = 127.0.0.0/8
  no_more


begin transports

remote_smtp:
  driver                = smtp
  delay_after_cutoff    = false
