VE configuraton was changed and the VE was restarted. During the restart operation, Virtuozzo node failed.
The most probable reason of the problem is incorrect processing of files, that were mapped from shared folder or via RDC and locked by MRxSMB (SMB client Kernel Driver) or rdprdr (RDP disk redirector driver) respectively, what leads to accessing invalid (non-existent) memory during VE shutdown.
Please run Virtuozzo Update Wizard and install Virtuozzo updates up to VZU35143
