I then have next-to-no internet for the rest of the month...) [snip] I had the same problem when a faulty modem made my connection rather unreliable. I solved it by limiting get_iplayer and its subprocess to only ten minutes of CPU time each. This is ample for normal use but ensures that rtmpdump will spin for up to ten minutes and then be killed off. I just put this in my download script: ulimit -t 600 If you persist with trying to kill get_iplayer you might like this patch that ensured get_iplayer cleans up after itself when it receives more signals: -- commit a2f38bedebe4ea412f59f686d2a07ab60bf181f2 Author: Mike Crowe <[email protected]> Date: Tue Aug 6 19:29:10 2013 +0100 Clean up on more signals diff --git a/get_iplayer b/get_iplayer index ea6c034..9df2520 100755 --- a/get_iplayer +++ b/get_iplayer @@ -497,7 +497,7 @@ for ( progclass() ) { } # Setup signal handlers -$SIG{INT} = $SIG{PIPE} = \&cleanup; +$SIG{TERM} = $SIG{HUP} = $SIG{ALRM} = $SIG{INT} = $SIG{PIPE} = \&cleanup; # Other Non option-dependant vars my $historyfile = "${profile_dir}/download_history"; HTH.
