I have a B2 to host my Squeezesbox database (Squeezeserver 7.5.4.dfsg1-2)
I initially loaded about 8000 flacs and all worked well.
I then ripped the rest of the collection (30000 songs in total). I kicked off the database scan which appeared to complete after about 2 days. Following this I couln't log in to the server nor could the squeezebox see it.
I checked the system log and it showed the scan proess was repeated every 20 minutes and that there were 5 erros due to duplicate items. I removed these albums and that error message disappeared but the scan process continued to cycle. The following is an extract from the system log:
Jun 19 18:39:48 bubba mt-daapd[2437]: Rescanning database
I ssh'd in the B2 and confirmed the squeezeserver process was running (consuming most of the CPU) but seemed to restart every 20 or so mins. The squeezerserver log confirmed that the squeezeserver died every 20 mins and restarted.
Any suggestions? Is there a limit on the no of songs the database can handle or are there some corrupted songs?
I had similar problems when trying to add a large number of songs (> 20,000). Not sure if it's due to a limitation with the B2's hardware or a bug in the software but I think you'll need to a bit of trial and error to see what the song limit is.
In the config of bubba's mt-daapd server (bubba:3689) you may set the scanning interval (in seconds), standard is every 600 seconds (10 min). You might even set it to once daily.
When using SSH the config file is in:
/etc/mt-daapd.conf
Thanks Random and Binkem
I altered the mt-daapd scan rate and it is currently not running.
The log indicates that mysql is still cycling and squeeze server is running on top but doesn't appear on the system log. Latest system log dump appears to be a memory problem:

This repeats about 6 times every 15 minutes or so.
I get the feeling that the best way forward might be to nuke the system and start again with fewer songs to begin with. I have seen a few posts on purging squeezeserver and reinstalling it. Will this deal with the mysql issues as well?
Hm actually it does not look like is it the same memory problem. If I read the log correctly it seems you do not have any swap at all on the machine. What does
I reinstalled my bubba system on a new HDD and I've got the same swap settings.
Can anyone point out how to create and activate a swap partition on the Bubba?
Here is my output. The interesting thing here is the Linux Swap which have the id 8e

That should definitely be reported to Excito since that is no good.
You could create your own swap partition with either
fdisk,cfdisk,sfdisk or parted, I would probably use parted since this is the most advanced of them. But this is only easy to do if you actually have unused space on the hard drive. If you do not have that you need to first shrink one of the current partitions and then it gets more complicated. parted should most likely be able to handle that to but it is a little more risky.
I have installed the B2 on a new HDD since my old one kind of stopped working after dropping it on the floor from my window frame .
It might depend upon the size of the HDD sinze the script needs to adapt the partitions to the size of the HDD.
I unfortunately do not now any easy way to unpack the installer to look at the installs script more than actually booting the bubba in rescue mode. It would be nice if you could do that on an other computer too try to understand what might be wrong or if you just want to modify it yourself.
