I got similar results in the /proc/nn/ dir for telnetd.

I did confirm that a sync fails even if the program does not have any files open during the sync. The sync the fails with the emplode message: Syncronization faid while checking media, 0xc0041010.

I couldn't interpret anything from roger's error code table from that one. I don't think it's in there.

This however is the serial output when the sync fails:

Adding Swap: 16596k swap-space (priority -3)
e2fsck 1.19, 13-Jul-2000 for EXT2 FS 0.5b, 95/08/09
ext2fs_check_if_mount: No such file or directory while determining whether /dev/
hda4 is mounted.
Restored terminal settings
Remounting first music partition read-only

Maybe that "ext2fs_check_if_mount" line will tell you something. Let me know if I can help with anything else.
