Oh, maybe I see the problem: this folder is on a non-Unix fiale system so it's probably not possible to have Unix sockets there. I'd think that this would properly produce a different error (not ENOENT) but who knows what happens in weird corner cases. On Mon, Jan 19, 2015 at 03:34:59PM -0800, Bo

1. To answer your question, if two files have the same name, deleting one will delete the other. 2. I meant to amend this "just guessing, possibly" but I hit send too early ;-) 3. Is NTFS also case-insensitive by default? Could be a possible issue there too. 4. The Linux kernel cannot be built on

These can be caused by a few different things e.g. if you are firing in packets at line rate then you will always see some errors here as the FIFO’s will fill up. However, with the amount of errors you are seeing and the fact that you’ve reported a 66 byte packet, I would start by checking that

Flow may not mean TCP connection with the current implementation. OVS uses wildcards to cover the largest amount of traffic with the smallest number of flows to improve performance. In theory, if MSS clamping were enabled, it could force the installed flows to match TCP connections; in practice thi
