Issue with workflow step sequence at runtime

Hi All,

I've a very strange case where step 3 is triggered before step 2. Details are as below.

Step Sequence                                                                                              Status                             Completed On

Step 1. Calculate deadline date - Date calculated as 18/03/2014                  Completed                        15/03/2014               

Step 2. Dummy step with requested start                                                       Waiting

Step 3. Send mail notification                                                                          Completed                       16/03/2014

This step sequence go in loop for 3 times before proceeding to processing Obsolete and all the three times I get the same issue.

Has anyone faced something similar or can throw some light on this issue?

Thanks,

Raj
