HTTPD Alarm Clock

When your apache web server dies when starting with a message that goes something like “alarm clock” or SIGALARM, your solution is to get rid of the file:

/var/run/httpd.pipe

Strace helped to track this one down:

[admin@theSuperStar] httpd # strace /usr/sbin/httpd
open("/var/run/httpd.pipe", O_WRONLY|O_CREAT|O_APPEND|O_LARGEFILE, 0666) = ? ERESTARTSYS (To be restarted)
--- SIGALRM (Alarm clock) @ 0 (0) ---
+++ killed by SIGALRM +++

[admin@theSuperStar] httpd # mv /var/run/httpd.pipe /var/run/httpd.pipe.off
[admin@theSuperStar] httpd #/etc/init.d/httpd start 
Starting httpd: [  OK  ]

Serviio and high quality LPCM audio output

So a quick post here. If you want your Serviio instance to push 16-bit, 2 channel LPCM audio to your DLNA client or renderer, you need to configure your audio profile like this:

<Audio targetContainer="lpcm" aSamplerate="48000" aBitrate="1620">

Basically, aBitrate=”1620″ for LPCM means 16 bit 2 channel. The default (as of this writing) appears to be 192, which makes no sense, and gives you horrible 1-bit 2 channel LPCM.

If you need help with editing the audio profile, read this slightly technical article: http://www.serviio.org/index.php?option=com_content&view=article&id=16 

Now go have fun 🙂
