[exim] Bad file descriptor is manualroute

Hi everyone

This is my router

route_scanned_mail:
driver =manualroute
domains = /usr/exim/relayetrn
route_data = ${lookup{$domain}dbm{/usr/exim/routedata}}
transport = remote_smtp
no_more

This is the error I get

2004-09-20 16:15:38 H=smtp.x.net.tr [x.x.x.x] F=<x@???> temporarily rejected RCPT <sento@???>: failed to open /usr/exim/routedata as a db (v3/4) file: Bad file descriptor

Any ideas??

Thanx in advance
