we've enabled NAS replication into our NimBUS infrastructure. We noticed however that in some situations the order in which alarms arrive to the first NAS is not the same with which the NAS replicates them on the second (see attachments). In the attached document there are two images related to the transaction log of a series of alarms. In the first image you see the sequence as it came to the first NAS. In the second image you see the same sequence as has been repeated on the second NAS. Message ACK in the second NAS arrived before the others. Is it correct or a mistake of NAS?
Thanks for your help
