Hi, Thanks for your suggestions. Here is what I found. Please let me know if you need more information.
This error happens only with the /mnt/mp3 filesystem. Just to make sure it was not a filesystem inconsistency I fsck'ed it. It turned out to be fine. This is what mount returns: /dev/wd1a on /mnt/mp3 type ffs (NFS exported, local, noatime, nodev, nosuid, softdep) And the df output: ~% df -h /mnt/mp3 Filesystem Size Used Avail Capacity Mounted on /dev/wd1a 230G 217G 2.0G 99% /mnt/mp3 To make debugging that a bit easier I did the following: sudo /usr/libexec/locate.updatedb --searchpath=/mnt/mp3/Klassiek/Schoenberg/PelleasundMelisande which also reproduces the bug. The dirtree looks like this: ~% \ls -l /mnt/mp3/Klassiek/Schoenberg/PelleasundMelisande total 108256 -r--r--r-- 1 han nfs 14321130 Oct 7 2003 Schoenberg - Pelleas und Melisande - 01 - Ein wenig bewegt - zogernd.ogg -r--r--r-- 1 han nfs 11406273 Oct 7 2003 Schoenberg - Pelleas und Melisande - 02 - Sehr rasch.ogg -r--r--r-- 1 han nfs 9792736 Oct 7 2003 Schoenberg - Pelleas und Melisande - 03 - Langsam.ogg -r--r--r-- 1 han nfs 19796656 Oct 7 2003 Schoenberg - Pelleas und Melisande - 04 - Sehr langsam.ogg And /var/db/locate.database base64 encoded looks like this: LXVuc2FvZ2hyZ2dlbmVsY2hhc2FuU2UvbS5vem90c3Nzcm5yZ3Azb2VudG5nbmRuYm0ubGxs aWxlbGFrL2lzaW5pZ2llaG9nc2dlZ2V3ZXJlZ2VhZWRlZE1kLmRiZWFtU2NQZU1lTGE0MzIw MS9TL1AvS3dybGJFLQ4vbW50L21wMy9LbGGPaWVrL7Bob5SuhC9QnGxlYXN1bmRNnGlzYW5k ZR4+AAAAL1NjaG9lbmKnZyAtILGaqXMgdW5kILJsaYluZGUgLSAwMSAtIEVpbiB3lGlnIGKm qHQgLSB6b4VybmQuo2ceNQAAADIgLSBTZWhyIHJhc2NoLm9nZw4zIC0gs25niYyjZw40IC0g U2VociBsYW5nc68ub2dn I checked the md5 of the file which you get if you save this code to a file and run it through base64 -e and it's the same.
