[squid-users] New squid3 error : DiskThreadsDiskFile::openDone: (2) No such file or directory

Hi squids users,

I've made somes changes to my squid boxes (new fresh server, more
powerful). All seems to be ok, but now i've got some strange errors
(from time to time) on cache.log.
Exemple :
2010/01/15 18:59:47| DiskThreadsDiskFile::openDone: (2) No such file or
directory
2010/01/15 18:59:47| /data/cache/0C/6A/000C6ABE
2010/01/17 19:21:05| DiskThreadsDiskFile::openDone: (2) No such file or
directory
2010/01/17 19:21:05| /data/cache/03/5C/00035C53
2010/01/17 19:21:05| DiskThreadsDiskFile::openDone: (2) No such file or
directory
2010/01/17 19:21:05| /data/cache/03/5C/00035C53
2010/01/17 19:21:05| DiskThreadsDiskFile::openDone: (2) No such file or
directory
2010/01/17 19:21:05| /data/cache/03/5C/00035C53

Squid version :
2010/01/14 10:32:53| Starting Squid Cache version 3.0.STABLE8 for
x86_64-pc-linux-gnu...

Did someone have already see this beforce ?
Google seems not to be my friend on these errors. :(

Data directory is a reizerfs FS dedicated to cache files dans squid logs.

It seems, that squid could not open a cache file. But kern.log and
message didn't have any clue to help me. :(

Thank you. :)
