Ok, then it's definitely a bug, not "just" a performance issue. >> If you reboot, can you get it again to consume that much CPU >> i.e. is the problem (easily) re-producable? > > It starts consuming CPU as soon as it starts, and keeps going. But only if your MMC is in when you reboot? Does "dmesg" tell anything? What happens if you remove MMC? Does the device complain that your MMC is in use? If it does, what is the output of following: for pid in $(pidof metalayer-crawler); do ls -l /proc/$pid/fd; done (Does it list any files from the MMC?) >> Could you file a bug to Maemo bugzilla about this (with the above info) >> and send link to the bug here? > > Sure, I was only trying if that was my fault or a real bug. Please attach also result of this (contents of MMC triggering the bug): ls -lR /media/mmc1/ to the bug report. AFAIK the crawler digs out extra information from some file types and it might be some specific file that is triggering the problem (e.g. because the file is broken in some specific way which triggers a bug in crawler), or the amount of files (e.g. of certain types). >>> [...] >>> 1) Has anyone else experienced same problem. >>> 2) Could the absence of the daemon, be a problem for other applications >>> (i.e. Media Player)? >> Not sure, but I think Mediaplayer gets the files in its "library" >> from the crawler database. > > I'll try then Thanks! - Eero PS. I tried triggering the bug by creating some partial mp3 files: cd /home/user/MyDocs/.sounds/; for i in $(seq 20); do out=/media/mmc1/test-$(($i+10)).mp3; dd bs=102400 count=$i if=Road_To_Ruin.mp3 of=$out; done; sync And re-inserting the MMC, but at least that didn't trigger the bug.
