I've a little program that uses the Sqlite database. After it calls
seven times fsync (sometimes only twice), the whole process blocks. The
process cannot be killed (-9) anymore, and when I change into the
directory where I executed the program and do a "ls", I'm blocked as
When I execute the same program on a UFS partition, it doesn't hang. So
it seems to be a Hammer-related issue.
According to ktrace/kdump, it hangs on fsync.

I'm now creating a core-dump and uploading it.
