CPU going high 100%+

[sound selecta]

I switched from MPC with mp3 to ogg to MPC mp3 and seems steamcast eats up CPU 100%+ once in a blue moon and stops responding.

This is what I saw in the tmux session but non of this if is in the log file.

Hmm just happened again. Same error messages in the tmux session.

[Jay]

Can you send your specific encoder details?

Hi

This is what I got in mpd.conf

Code: Select all

# An example of a shout output (for streaming to Icecast):

        type            "shout"

        host            "ice.futureassassin.com"

Seems to go haywire on some tracks so maybe the encoding on the tracks is wrong? I'll try to check each tracks encoding tomorrow.

[sound selecta]

Ok looking at some track through Kid3 I can see

Mojority of track are 128KB 44100 joint or stereo

Some are 128KB 48000

and for some kid3 doesn't shows the encoing info.

[Jay]

Does this tool just stream the track directly to Steamcast without encoding it?

[sound selecta]

I believe no encoding in mp3 to mp3 since I see minimal CPU usage vs when going from mp3 to ogg. I re econded all files to 41000 and will see if it still crashes. Since it didn't when going from MP3 to OGG I guess the 48000 files where maybe causing some issues.

[Jay]

K, will do some testing on the 48000 hz encoding.

[sound selecta]

I could zip up the files that I think were causing the issues if you want and pm you the link.

[Jay]

that would be great, thanks.

[sound selecta]

Well sopke too soon. Just happened again but not sure how I can detect when it happens to see if its a track that is causing it or something else. It never happned when going from MP3 to OGG.

I guess I can write the tmux output to file then check when is starts to go high.

This issue is due to too many IO handles being open on your system.

I suggest checking ulimit if this is Linux.

Hmm thanks I'll look into it when I restart my station over the holidays. Yes this was on Ubuntu serer 12.04 I believe what I was running.

[Max]

The new 1.0.1 release should handle this condition better. By properly warning that the system is not allowing it to open anymore IO handles.

[Max]

Ok, I believe 1.0.2 will have fixed this problem for you. We had a Socket leak that would allow Steamcast to fail to close sockets on Linux. This has been fixed in an update build of 1.0.2 as described in the announcement.
