Are there log files associated with this toolbar? I was running the Add Laterals to Connection tool on about 600 features overnight and in the morning I saw this message window:

then after clicking through several of the above dialogs I was unable to save my edits.

I had to exit ArcMap without being able to save. Upon re-opening the MXD I could see that the last feature created was at 2/27/2016 3:15:44 AM. Fortunately, it did save up to that point (I'm running this against a named version in SDE) and I was able to post and reconcile.
The only process that was occurring against the SDE database at that time last night were routine backups.
I don't know if a log file would have been helpful in this case.
