Thanks for reporting.

The slimserver start script creates both slimserver group and user. Isn't there a message 'Adding slimserver group' before the slimserver user message?

What shadow version is installed? I think there was a problem with an earlier version (unfortunately, I don't remember the details).

root@bob:~# ls /ffp/var/packages/shadow*
/ffp/var/packages/shadow-4.1.2.1-1

packages today installed from your server

I updated shadow on Aug 27. Please try the latest version.

Maybe you installed from a different directory with older packages? Also, if you re-download to the same directory, be sure to add '--delete' to your rsync command, so that it removes old packages.

Anyway, glad it works.

fonz, i managed to install all the perl packages and the squeezecenter-7.3.2-1 package from the extra folder on your web server and can access the web interface. However, I found that whenever I do a scan on my music folder (only have like 1000 songs max), squeezecenter will crash after some 15-30mins. The last message in the scanner log will be something like this:

Any ideas what is wrong with my setup?

Hi Fonz,

Thanks for the prompt reply. I am already using most of the settings you have other than "skip-networking" and "skip-bdb". I'm guessing my problem could be timeout on the slimserver side as only slimserver crashed while mysql still runs fine. Oh, another point to note is that I have the db files stored on my USB partition rather than the harddisk. I read somewhere that USB writes are slower than HDD hence maybe that could be the problem?

[EDIT: Looks like my problem went away when I configure slimserver to use TCP/IP instead of named pipes. i.e. I changed the dbsource to "dbi:mysql:hostname=localhost;port=3306". Also, I found a way to reduce the amount of memory used. Turn off those plugins that are not relevant to you! I turned all the online music services off and my memory usage dropped from 135% to 113%.]

Thank you for those hints.
SqueezeCenter on my DNS-323 struggles with the low memory conditions too, so any advice is appreciated. I've tried some diffent configs, gathered by combining several posts on this forum.

About 8000 audio files on the NAS, only a fraction has cover art at the moment.

1. FFP & SC on the HD
SqueezeCenter itself is stable, but the scanner suffers from disconnects about 30% of the time.
Delete database & complete rescan time: about 2 hours 30 minutes.
HD's usually do not spin down because of constant swapping.

2. FFP & SC + Swap on USB.
Very slow and not stable at all. The nightly scan would bring down everything on the NAS about 50% of the time. Even holding te power button didn't shut it down.

3. FFP & SC on HD, Swap on USB (running like this at the moment)
SqueezeCenter seems to run well, the nightly scan still hangs the unit once a week.
Scanner sometimes disconnects from database, but not frequent.
Delete database & complete rescan time: over 5 hours (2 for audio, 3 for cover art)
HD's do spin down after 5 minutes when it's not streaming music.

At the moment, I disabled the nightly scan. I'll scan manually before going to sleep when I add files to the unit.
Another issue: Scanning with the faster settings 'Search for new and deleted files' never completes. The last step keeps running and slows down the entire unit.

I'd like to try moving the ramdisk from RAM to USB. This might reduce swapping.
The steps to do this are not yet clear to me. (especially getting the ramdisk image file)
Is there a way to check actual I/O speeds from withing the OS? I'd like to compare the transfer rate of the USB stick versus the HD's. The USB stick feels very slow.
