[Pdns-users] Error with rec_control reload

[MRob]

Hi can anyone explain what this means and if it is important or can be 
ignored? I only find unanswered mailing list posts about it.

$ sudo rec_control reload-lua-script
pdns_recursor: Error dealing with control socket request: Unable to send 
message over control channel '/var/run/lsockl2eLnQ': No such file or 
directory

Because of this error do I presume reload failed? Must I execute service 
restart of recursor?
