Hi,

I have a SB3 with 7.5.2. While playing internet radio stations, the CPU on the SB server will eventually get pegged at 100%, and the SB3 will lose connection. This never occurs with music or podcasts from my own library. It can take 20-30 min. to regain control of the server once this occurs.

Is there a fix?

The SB server is installed on an older Compaq SR2139, with AMD Athlon 64 CPU, and 2GB RAM, clocked at 2.2 GHz.

Thanks and regards,

Rob

More info will help.

What format is the audio stream being played ?
Have you changed default settings ?
What process is taking bulk of CPU time according to Task Manager ?

For WMA and MP3 stream - they will be played directly by SB3 and will have no load on the SBS server.

For other stream format - the stream will have to be transcoded and this can cause a CPU load but it is usually small for a normal PC.

Have you tried updating to 7.5.4?

That sounds like IO starvation more than anything.

It would also help to know what OS you're running.

No, I was concerned that this rev was buggy, based on reports on this forum.

What is that?

Windows XP, SP3. All updates current.

Other applications on this machine are iTunes and Microsoft Antivirus. Not much else.

ALAC

What is the URL so others can test ?

I think is unlikely to be IO starvation given the processor size and you are playing an internet stream which are not that fast.

I think it is more likely that something is interfering (e.g. security s/w) with the transcoding processes and blocking data.
