Hi Obaid, no, it's not, look at the trace I got. :)

Hi Ralph: As I said in my email before below, epoch bump does happen. Please see the network capture attached to this email for test case 1. Please look at frame 123 where epoch is bumped to 2 when lease is downgraded to none.

When no taking a brl in an otherwise unchanged scenario, the R lease is maintained and not dropped. The interesting question is: *why* this difference?

I've created case 2508130040006013 to track the issue. One of our engineers will investigate this and reach out to you soon.

Here comes another one related to Persistent Handles... I see the following behaviour against a Windows server with Fileserver for General Use role: 1. Client 1 opens file with PH, lease=R and sharemode=none 2. Client 1 disconnects TCP connection 3. Client 2 tries to open file and gets STATUS_FILE_NOT_AVAILABLE 4. Client 1 reconnects SMB 5. Client 1 reconnects PH, this succeeds but the lease is downgrade to NONE but the lease epoch is still the same as in step 1, iow it is not bumped Is this expected behaviour? There's footnote 247 in "3.3.4.7 Object Store Indicates a Lease Break" but none of the cases described there seem to cover my scenario. According to the SDC presentation "SMB 2.2 : Bigger, Faster, Scalier (Part 2)" from 2011, page 50, the server must bump the lease epoch. Can you please clarify? Traces (pcap + t.cmd) available. Thanks! -slow
