Subject: [PATCH] Ticket 49631 - same csn generated twice
|
|
|
96373c |
|
|
|
96373c |
Bug: if in the csn adjustment the local time was less or equal than the remote time
|
|
|
96373c |
the sequence number has always been adjusted to remote++
|
|
|
96373c |
but if the csn time was equal and the local seq number was larger the effect
|
|
|
96373c |
was a reset of the csn generato.
|
|
|
96373c |
|
|
|
96373c |
Fix: correctly handles seqnum in csn adjustment
