[icecast] ices crash

[David M Dennis]

Dear List,

Running icecast 1.3.11, ices 0.2.2, 

I've been running six streams on one server, PII 333 mhz intel / linux
kernel 2.2.17 .  (icecast and six instances of ices, all are 32kb streams)

Most of the time things work but occasionally, the following happens and
one or more ices streams crash --

<p>Would it matter that some of the playlists are located on SCSI rather than IDE ?

Also - this is using mp3 not ogg.  lame is compiled in, but I am not 
re-encoding, load avg's have been in the 0.10 - 0.40 range, this is
also due to this being an X desktop box as well as icecast server.
(so load doesnt seem to be inordinately high with ices prior to these crashes)

<p>Thanks,

-Dave D
