Well it’s an OOM. Are you using sqlite2 or sqlite3 as database?
What binary do you use, or did you compile yourself?

It’s indeed weird that that initial scan works, so I suspect database trouble.

Aye – that’s what bothered me too… What would be different in scanning at start up but not via the web interface?

Anyways, to answer your questions, I am using sqlite3, and I compiled myself.

My steps for compiling were as follows:

./configure --enable-sqlite3 --with-sqlite3-includes=/usr/include --with-sqlite3-libs=/usr/lib64
make
make install

My configuration file resides at /usr/local/etc/mt-daapd.conf and is as follows:

# $Id: mt-daapd.conf.templ 1660 2007-09-12 13:08:04Z rpedde $
#
# This is the mt-daapd config file.
#
# If you have problems or questions with the format of this file,
# direct your questions to [email protected]
#
# Questions and discussions about the format and content of this
# config file can probably be obtained by consulting the wiki:

# http://wiki.fireflymediaserver.org/Config_File

# Or by asking questions on the forums at

[general]

#
# web_root (required)
#
# Location of the admin web pages.
#
# If you installed from .RPM, .deb, or tarball with --prefix=/usr, then
# this is correct.
#
# If you installed from tarball without --prefix=/usr, then the correct
# path is probably /usr/local/share/mt-daapd/admin-root.
#

web_root = /usr/local/share/mt-daapd/admin-root

#
# port (required)
#
# What port to listen on. It is possible to use a different
# port, but this is the default iTunes port
#

port = 3689

#
# admin_pw (required)
#
# This is the password to the administrative pages
#

admin_pw = mt-daapd


#
# db_type (required)
#
# This is what kind of backend database to store the song
# info in. Valid choices are "sqlite" and "sqlite3".
#

db_type = sqlite3

#
# db_parms
#
# This is any extra information the db needs to connect.
# in the case of sqlite and sqlite3, this is the name
# of the directory to store the database in
#
# If you installed from RPM or .deb, this path likely already
# exists. If not, then you must create it. The directory itself
# must be writable by the "runas" user.
#

db_parms = /usr/local/var/cache/mt-daapd

#
# mp3_dir (required)
#
# Location of the mp3 files to share. Note that because the
# files are stored in the database by inode, these must be
# in the same physical filesystem.
#

mp3_dir = /media/music

#
# servername (required)
#
# This is both the name of the server as advertised
# via rendezvous, and the name of the database
# exported via DAAP. Also know as "What shows up in iTunes".
#

servername = Firefly %v on %h

#
# runas (required)
#
# This is the user to drop privs to if running as
# root. If mt-daapd is not started as root, this
# configuration option is ignored. Notice that this
# must be specified whether the server is running
# as root or not.
#
# This is also ignored on Windows.
#

runas = nobody

#
# password (optional)
#
# This is the password required to listen to MP3 files
# i.e. the password that iTunes prompts for
#

#password = mp3

#
# extensions (optional)
#
# These are the file extensions that the daap server will
# try to index and serve. By default, it only indexes and
# serves .mp3 files. It can also server .m4a and .m4p files,
# and just about any other files, really. Unfortunately, while
# it can *attempt* to serve other files (.ogg?), iTunes won't
# play them. Perhaps this would be useful on Linux with
# Rhythmbox, once it understands daap. (hurry up!)
#
# Failing that, one can use server-side conversion to transcode
# non-standard (.ogg, .flac) music to wav on the server side.
# See the ssc_* options below.
#
# To be able to index .ogg files, you'll need to have configured
# with --enable-oggvorbis. For .flac, --enable-flac, for .mpc,
# --enable-musepack.
#

extensions = .mp3,.m4a,.m4p

#
# ssc_codectypes (optional)
#
# List of codectypes for files that the daap server should
# perform internal format conversion and present to clients
# as WAV files. The file extensions that these codectypes correspond
# to must also be present in 'extensions'
# configuration value, or files are not probed in the first
# place.
#
# Valid codectypes:
#
# mp4a - for AAC (.aac, .mp4, .m4a, .m4p)
# mpeg - for mp3
# wav - for wav
# wma - for wma
# ogg - for ogg
# flac - for flac (.flac, .fla)
# mpc for musepack (.mpc, .mpp, .mp+)
# alac for alac (.m4a)
#

ssc_codectypes = ogg,flac,alac

#
# ssc_prog (optional)
#
# Program that is used in server side format conversion.
# Program must accept following command line syntax:
# ssc_prog filename offset length ...
# Parameter filename is the real name of the file that is
# to be converted and streamed, offset is number of bytes
# that are skipped from the beginning of the _output_ file
# before streaming is started, length is length of the song
# in seconds (or zero). All other possible arguments must
# be ignored. The resulting wav file (or the rest of
# the file after initial seek) is written to the standard
# output by the ssc_prog program. This is typically
# a script that is a front end for different conversion tools
# handling different formats.
#

ssc_prog = /usr/local/bin/mt-daapd-ssc.sh

#
# logfile (optional)
#
# This is the file to log to. If this is not configured,
# then it will log to the syslog.
#
# Not that the -d switch will control the log verbosity.
# By default, it runs at log level 1. Log level 9 will churn
# out scads of useless debugging information. Values in between
# will vary the amount of logging you get.
#

logfile = /var/log/mt-daapd.log

#
# rescan_interval
#
# How often to check the file system to see if any mp3 files
# have been added or removed.
#
# if not specified, the default is 0, which disables background scanning.
#
# If background rescanning is disabled, a scan can still be forced from the
# "status" page of the administrative web interface
#
# Setting a rescan_interval lower than the time it takes to rescan
# won't hurt anything, it will just waste CPU, and make connect times
# to the daap server longer.
#
#

#rescan_interval = 300

# always_scan
#
# The default behavior is not not do background rescans of the
# filesystem unless there are clients connected. The thought is to
# allow the drives to spin down unless they are in use. This might be
# of more importance in IDE drives that aren't designed to be run
# 24x7. Forcing a scan through the web interface will always work
# though, even if no users are connected.

# always_scan = 0

#
# scan_type
#
#
# This sets how aggressively mp3 files should be scanned to determine
# file length. There are three values:
#
# 0 (Normal)
# Just scan the first mp3 frame to try and calculate size. This will
# be accurate for most files, but VBR files without an Xing tag will
# probably have wildly inaccurate file times. This is the default.
#
# 1 (Aggressive)
# This checks the bitrates of 10 frames in the middle of the song.
# This will still be inaccurate for VBR files without an Xing tag,
# but they probably won't be quite as inaccurate as 0. This takes
# more time, obviously, although the time hit will only happen the
# first time you scan a particular file.
#
# 2 (Painfully aggressive)
# This walks through the entire song, counting the number of frames.
# This should result in accurate song times, but will take the most
# time. Again, this will only have to be incurred the first time
# the file is indexed.
#

scan_type = 2

#
# compress
#
# Whether to use gzip content-encoding when transferring playlists etc.
# This was contributed as a patch by Ciamac Moallemi just prior to the 0.2.1
# release, and as such, hasn't gotten as much testing as other features.
#
# This feature should substantially speed up transfers of large databases
# and playlists.
#
# It will eventually default to 1, but currently it defaults to 0.

Out of curiosity, when you say “its an OOM” what are you referring to?

Are there any commands you can think of that might help troubleshoot the database? Perhaps some sort of log I can take a look at that specifically deals with the database?
