Hello,
I have recently setup 2 dfsn & dfsr servers, both 2012 one physical the other virtual.
The idea is to have one server as primary and the other as a failover \ DR.
The primary server is virtual and connects via mpio \ iscsi to a dell san, using the provided dell DSM Drivers.
The secondary server is physical with local disk for storage.
I copy files to a namespace setup to always prefer the primary server, these files are then replicated across to the secondary.
I have also turned on deduplication on both servers to get the most out of the available storage.
This has been working well for 6 months or so, there have however been 2-3 occasions where the primary virtual server has crashed and blue screened causing the DFSR database to undergo a full consistency check.
The bug check errors i have managed to extract from the Memory.dmp and mini dump are as follows:

REFERENCE_BY_POINTER (18)
Arguments:
Arg1: 0000000000000000, Object type of the object whose reference count is being lowered
Arg2: fffffa80379a3070, Object whose reference count is being lowered
Arg3: 0000000000000002, Reserved
Arg4: ffffffffffffffff, Reserved
The reference count of an object is illegal for the current state of the object.
Each time a driver uses a pointer to an object the driver calls a kernel routine
to increment the reference count of the object. When the driver is done with the
pointer the driver calls another kernel routine to decrement the reference count.
Drivers must match calls to the increment and decrement routines. This bugcheck
can occur because an object's reference count goes to zero while there are still
open handles to the object, in which case the fourth parameter indicates the number
of opened handles. It may also occur when the object?s reference count drops below zero
whether or not there are open handles to the object, and in that case the fourth parameter
contains the actual value of the pointer references count.

I have searched for others having a similar problem but have not managed to find much.
The memory dump at the time of the crash does seem to hint at a problem with DFSR.exe.
The setup seems to be running fine again now and is going through its consistency checks, it is just a major inconvenience and will only get worse as the DFS becomes busier and approaches capacity.
The plan was to put this setup into production however with the unpredictability of blue screen reboots I cannot see this happening until I can find a fix or work around.
I have yet to see this problem occur on the other (physical) server, this is pretty much identical in configuration apart from its storage access.
My thoughts are a possible bug in the DFSR component or a bug in the DSM Drivers used for the iSCSI SAN connection or maybe a combination of the two.
Any help, thoughts or suggestions greatly appreciated
Thanks
