330	pdns-recursor doesn't respond to rec_control after reloading erroneous ACL file	anon	ahu	"First we check with a correct ACL file:

gimre@voy:~$ cat /tmp/foo.lst 
127.0.0.1
gimre@voy:~$ grep foo /tmp/recursor.conf 
allow-from-file=/tmp/foo.lst

gimre@voy:~$ sudo /tmp/pdns-recursor-3.3.1/rec_control --config-dir=/tmp reload-acls
ok

Then we write something in the ACL file, which cannot be parsed:

gimre@voy:/tmp/pdns-recursor-3.3.1$ echo ""uuuuu"" > /tmp/foo.lst 
gimre@voy:/tmp/pdns-recursor-3.3.1$ sudo ./rec_control --config-dir=/tmp reload-acls
Fatal: Unable to receive message over control channel: Success

In the logs we see the following error message:

Dec 15 00:10:37 Exception: Unable to convert 'uuuuu' to a netmask

After this, the recursor does not respond to any rec_control commands OR USR1 signal (for stats). Only a restart seems to work.

gimre@voy:~$ echo ""127.0.0.1"" > /tmp/foo.lst 
gimre@voy:~$ sudo /tmp/pdns-recursor-3.3.1/rec_control --config-dir=/tmp reload-acls
Fatal: Unable to receive message over control channel: Success
