I've now received an MMC which triggers this bug. The FAT file system on this MMC is corrupted. I.e. you would see in dmesg messages about FAT errors and the crawler has some files open which names are complete (200 bytes long) garbage. Most of the MMC contents seemed OK though and I think that's why it was mounted. Please check whether all the file names on your MMC look alright and fsck it. If this doesn't cure the problem, more information about the problem is needed. - Eero ___ maemo-users mailing list maemo-users@maemo.org https://maemo.org/mailman/listinfo/maemo-users

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. ___ maemo-users mailing list maemo-users@maemo.org https://maemo.org/mailman/listinfo/maemo-users

Hi all, first of all I have to say that I am *very* impressed by the N800, great device! By the way, I just found metalayer-crawler0 is eating up a lot of CPU, I have 4 processes, and at least one is eating at least 50% of my CPU, all the time. As far as I discovered, metalayer-crawler is in charge of collecting information about the comings and goings of media files in the system. The metadata of media files is automatically extracted using Libmetalayer for other applications to use. I ended up to completely disable the daemon. My questions: 1) Has anyone else experienced same problem. 2) Could the absence of the daemon, be a problem for other applications (i.e. Media Player)?

Re: [maemo-users] metalayer-crawler
Quick upgrade. If I'm not wrong, the crawler explore the *whole* filesystem, and thus eating so much CPU (and resources). A quick work around could be to watch only thos directoryes which are likely to contains media files: /home/user/MyDocs/.video /home/user/MyDocs/.sounds /home/user/MyDocs/.images invoking with: media-crawler -F -c /home/user/MyDocs/.video,/home/user/MyDocs/.sounds,/home/user/MyDocs/.images I added a MEDIAPATH variable to /etc/init.d/metalayer-crawler0 script and added it to metalayer-crawler invocations in the same script. CPU consumption is now ok. I'm going to open a bug this evening from home. Bye william maddler wrote: Hi all, first of all I have to say that I am *very* impressed by the N800, great device!
