Hmmm... The bug I was thinking of (affected ext3 with dir_index if you didn't use no_subtree_check) was fixed will before 2.6.17 came out. What filesystem are you using? If ext3, what does tune2fs -l /dev/XXXX say (for the device holding the filesystem). > > I'm not familar with tcpdump.

If no_subtree_check fixes it, then tcpdump won't show us anything interesting. NeilBrown ------------------------------------------------------------------------- Using Tomcat but need to do more?
