I use iTunes as the main database for all my music.  This has always worked 
fine.

I noticed, while using a Slimbox, that certain artists/albums were now missing 
(previously they were present).  I had set the new option of re-scanning the 
database at a set time on my server - so thought it could be this.

I ran the slimserver web interface and found that only a 1/3 of my albums were 
present.

I decided to run the "wipe cache" function.

I waited a while and selected "browse artists" in the web interface - and the 
list that is normally shown as "A B C D E F ... X Y Z" now showed "A B S B A B 
P A B A T A ...".  I have taken a screen shot that you can find at 
www.moyo.me.uk/squeezebug.

Even when the scan was complete, the list was the same.

When I checked the albums, only A to M were listed.

I decided to re-boot the server PC.  When this booted, Windows XP reported 
that there was an error with "slim.exe" and asked if I wanted to report this.

I started the server, chedcked the settings with respect to iTunes (I have 
manually set the directories for the xml etc files) and all was correct.

I again did a "wipe cache" and this time all was fine.

I have not been able to repeat the problem so far.

Perhaps the code for lisiting A to Z could be made more robust, so that if 
there is a corruption of some sort this could be reported, rather than 
lisiting random letters?
