Pulse Audio appears to be causing HD to thrash repeatedly
 
Mandriva 2010, Gnome 2.28, PulseAudio 0.9.19-7mdv2010.0. I'm seeing
about 4 - 5 minutes of drive thrashing intermittently throughout the
hour. Looking at my syslog I see entries such as this:

and on and on and so forth. Among other problems this is causing
SpamAssassin to take a very long time to scan a message. Before
upgrading to 2010 I was seeing scan times like:

Spam: 5 Autolearn: 0 AvgScore: 31.40 AvgScanTime: 5.24 sec
Ham: 17 Autolearn: 0 AvgScore: -2.35 AvgScanTime: 17.40 sec

Now due to this almost constant drive access I'm seeing scan times like:

Spam: 21 Autolearn: 0 AvgScore: 19.38 AvgScanTime: 37.67 sec
Ham: 26 Autolearn: 0 AvgScore: -4.50 AvgScanTime: 27.56 sec

In fact while manually scanning a message awhile ago SpamAssassin
actually hung while the drive was being accessed.

Any advice for a fix or where to report this would be appreciated

1.) I am very sorry for you, I dropped pulseaudio from my own distros since day 1. I could recommend you do the same (google it) and deploy alsa + dmix instead (if necessary). That way you will not suffer those constant overruns, dumps and extra baggage. Most modern audio hardware does not even need software mix as manufacturing processes became cheaper. Many people will be safe without pulseaudio or things alike.
2.) As you appear to be using Mandriva, use their bugzilla reporting forms: http://twiki.mdklinuxfaq.org/en/Deve...Howto/Bugzilla

Thanks, I've de-selected pulseaudio in the Mandriva Command Center and things seemed to have settled down now. I'll watch it for a few days and see what happens. Thanks also for the link to reporting bugs in Mandriva.

For further information of any others reading this thread, I deselected pulseaudio after an update in 2009.1 screwed up my sound. Prior to the update it worked fine. I think pulseaudio must be buggy but as code933k says, who needs it!
