Geometric network connectivity issue

[nageshnangi1]

Reconcile fails and arcmap crashes where geometric network featureclass is modified. That featureclass is also ArcFM configured.

While trying to repair the feature using repair connectivity tool, error message is popping up 'repairconnectivity failed'.  Disconnect tool on particluar feature is also crashing the ArcMap.

Enterprise geodatabase with ArcGIS 10.1 SP1 and ArcFM Solution 10.1. All ArcGIS and ArcFM patches already installed.

Expecting some magic solution
