What OS are you running? I am running FreeBSD, and it doesn't support O_DSYNC. It seems that this flag ensures that writes to this fd ensure filesystem metadata is written out to disk with every write.
I added a #define O_DSYNC O_FSYNC to config.h. I don't think this will hurt anything but perhaps performance (if it is in fact necessary). I have seen references that O_FSYNC may even be a no-op on FreeBSD. Tim ----- Original Message ----- From: "Sergey N.
