Som information that would be useful: - did you run "e2fsck -f" to see if there were any errors in the filesystem? - do you run any specific applications that seem to trigger the problem (e.g. Vuze (formerly azureus) as was reported by another user) - do the applications writing to this file have any unusual IO pattern (e.g. mmap IO, lots of write+truncate+write on the same file, etc) We discussed the creation of a debugging patch to help diagnose this problem. It looks like you have already compiled your own kernel, so I assume it would be possible for you to run with an additional patch?
