Hi

Running multiple "configure" commands via birdc, while there is an error in configuration file, creates multiple file descriptors.

Scenario

CentOS 6.4 2.6.32-358.el6.x86_64

bird 1.4.0

birdc.conf main configuration file

comp.conf included in bird.conf

there a loop of "configure" and several "show" commands runs in a background to ease configuration debugging

after a while following error appears
/etc/bird/bird.conf, line 96: Unable to open included file /etc/bird/comp.conf: Too many open files

lsof provides thousands of the following

Only solution found is to restart the bird proccess
