After lots of testing, I can say that 2.5.18 works great in all three modes of ext3 for all but one purpose. Oracle database still gets corrupted during insert load. More precisely, online redo log gets corrupted, database panics and restore is in order. This leads me to thinking that there's something wrong with sysv shared memory in 2.5.x. Although the problem could also be in fsync() or swap_out() & co. paths, it's yet to be discovered. It could also be that journaled mode helps the trouble, and it could be that some swapping makes it more certain, but none of these two facts are proved for sure. Take it as an observation. Christoph, I don't know if you're still taking care of shmem in 2.5.x, so take my apologies if you didn't want to see this email. Regards, -- Zlatko
