[Icecast] icecast eating CPU in Debian

[Per Gunnarsson]

Hello!

I have had problems with icecast beginning to eat all my CPU lately.

I use the icecast2-2.4.4 source on Debian testing, I have recompiled it
for SSL support. The hardware is amd64.

I see nothing particular in the log files. One thing I can think of is
that I have liquidsoap asking icecast if some mount points are up. It
looks like this in the log files:

10.0.0.6 - - [22/Apr/2019:18:20:00 +0200] "GET /test.ogg HTTP/1.0" 404
394 "-" "Liquidsoap/1.3.7 (Unix; OCaml 4.05.0)" 0
10.0.0.6 - - [22/Apr/2019:18:20:01 +0200] "GET /verketlive.ogg HTTP/1.0"
404 394 "-" "Liquidsoap/1.3.7 (Unix; OCaml 4.05.0)" 0
10.0.0.6 - - [22/Apr/2019:18:20:02 +0200] "GET /test.ogg HTTP/1.0" 404
394 "-" "Liquidsoap/1.3.7 (Unix; OCaml 4.05.0)" 0
10.0.0.6 - - [22/Apr/2019:18:20:03 +0200] "GET /verketlive.ogg HTTP/1.0"
404 394 "-" "Liquidsoap/1.3.7 (Unix; OCaml 4.05.0)" 0
10.0.0.6 - - [22/Apr/2019:18:20:04 +0200] "GET /test.ogg HTTP/1.0" 404
394 "-" "Liquidsoap/1.3.7 (Unix; OCaml 4.05.0)" 0
10.0.0.6 - - [22/Apr/2019:18:20:05 +0200] "GET /verketlive.ogg HTTP/1.0"
404 394 "-" "Liquidsoap/1.3.7 (Unix; OCaml 4.05.0)" 0

Liquidsoap used to do this earlier for weeks without problem.

The hardware is pretty old, that's another thing I can think about.

Usually there is only one or two listeners connected when icecast starts
eating CPU.

I am grateful for pointers and clues.
