Unable to reconcile: the target version is currently being reconciled against

Configuration:

Oracle 12c (12.1.0.2 Oct 2015 PSU)

SDE 10.3.1 + Patches

ArcGIS Desktop 10.3.1

 

Background information:

-Feature classes are registered as versioned, but not with the move to base option.

-Concurrent users edit against default version, there are no explicit versions in the database

-Replicas exist for one-way replication to child database

-Editors save changes every 10-15 minutes, but will have the same editing session open throughout the day

-Editors could be concurrently editing the same feature class, though less common

-Attribute Assistant is used

 

Issue:

Since the upgrade, several users have reported receiving the following error message. 44648 - Unable to reconcile: the target version is currently being reconciled against  and have lost their edits as a result. It is understood that saving a large volume of edits at the same time to the default version could produce this error message.

 

Concerns:

This error message is more common since we have upgraded from SDE 10.2.2 to 10.3.1/Oracle11g to Oracle12c. Performance certainly has degraded with the upgrade despite the increased database memory allocation and could account for the increased chance of a long reconcile. However are there other factors that should be considered as to the cause of the error message?
