question about open_owner sequencing

Hi folks,

I have a question about recovery from the BAD_SEQID and what should happen.

I have the following application that does:

1. open(file1)
2. open(file2)
3. close(file1)
4. open(file3)
5. lock(file2)

If CLOSE gets BAD_SEQID (for whatever reason), I see that LOCK later
fails with BAD_SEQID as well.

step1 OPEN creates open_owner1 seq 0
step2 OPEN uses open_owner1 seq1
step3 CLOSE uses open_owner1 seq2 gets BAD_SEQID
step4 OPEN sends new open_owner2 seq2 and it triggers OPEN_CONFIRM with seq3
step5 sends LOCK with seq4 and open stateid from the reply in step 2.

LOCK gets BAD_SEQID.

Question: is client sending something incorrect? is server not
correct? I tested against two different servers (Linux and NetApp) and
both reply the same way so I'm leaning towards "no". But I don't see
why "seq4" is not a valid sequence given that the open_owner/sequence
was just confirmed.

Thanks.
