Bad directory data with multiple clients

Hi.

I'm connecting directly to our Elektron Edge Device, which has two services, ELEKTRON_AD and ELEKTRON_DD. I'm running software that instantiates multiple RFA client objects (derived from rfa::common::Client), using the same Session configuration. I'm using C++ RFA7.6.2.L1, I've also tried 7.6.1.E1, and 8.0.1.L1 (all win-shared, VS2013, windows 7).

The problem is that second and subsequent clients receive incorrect directory information.

To demonstrate the problem, example program "Consumer" (directory \Examples\Consumer in C++ RFA version 7.6.2.L1.win-shared) can be modified to show the problem. Modify Application.cpp, at line 157 insert "::Sleep(15000);". This makes the second and subsequent clients start up after a delay. Note that the problem doesn't manifest without the delay between clients starting up.

When configured with multiple clients, only the first client gets the expected directory data:

ConsumerClient_10 :
/Directory cache (Msg Refresh)
Service: ELEKTRON_AD  last action: Add
  INFO:
  ServiceId: 265

Second and subsequent clients get "bad" directory data:

/Directory cache (Msg Refresh)

My application configuration, which I would have attached but for whatever reason attachment upload isn't working:

\ConsumerClient_10\session = "Session1"
\ConsumerClient_10\service = "ELEKTRON_AD"
\ConsumerClient_10\itemList = "BHP.AX"
\ConsumerClient_10\msgModelRequestType = "marketPrice"
\ConsumerClient_10\msgModelDefaultDisplay = true 
\ConsumerClient_10\userName = "treprt"
\ConsumerClient_10\appId = "256"
\ConsumerClient_10\InstanceId = "<Instance Id>" 
\ConsumerClient_10\loadLocalDicts = false
\ConsumerClient_10\fieldDictionaryFilename = "./RDMFieldDictionary"
\ConsumerClient_10\enumDictionaryFilename = "./enumtype.def"
\ConsumerClient_10\directoryReqFilter = "SERVICE_INFO_FILTER | SERVICE_STATE_FILTER"
\ConsumerClient_10\SourceMirroringMode = "0"
\ConsumerClient_10\useEventQueue = true
\ConsumerClient_11\session = "Session1"
\ConsumerClient_11\service = "ELEKTRON_AD"
\ConsumerClient_11\itemList = "CBA.AX"
\ConsumerClient_11\msgModelRequestType = "marketPrice"
\ConsumerClient_11\msgModelDefaultDisplay = true 
\ConsumerClient_11\userName = "treprt"
\ConsumerClient_11\appId = "256"
\ConsumerClient_11\InstanceId = "<Instance Id>" 
\ConsumerClient_11\loadLocalDicts = false
\ConsumerClient_11\fieldDictionaryFilename = "./RDMFieldDictionary"
\ConsumerClient_11\enumDictionaryFilename = "./enumtype.def"
\ConsumerClient_11\directoryReqFilter = "SERVICE_INFO_FILTER | SERVICE_STATE_FILTER"
\ConsumerClient_11\SourceMirroringMode = "0"
\ConsumerClient_11\useEventQueue = true
\ConsumerClient_12\session = "Session1"
\ConsumerClient_12\service = "ELEKTRON_AD"
\ConsumerClient_12\itemList = "CBA.AX"
\ConsumerClient_12\msgModelRequestType = "marketPrice"
\ConsumerClient_12\msgModelDefaultDisplay = true 
\ConsumerClient_12\userName = "treprt"
\ConsumerClient_12\appId = "256"
\ConsumerClient_12\InstanceId = "<Instance Id>" 
\ConsumerClient_12\loadLocalDicts = false
\ConsumerClient_12\fieldDictionaryFilename = "./RDMFieldDictionary"
\ConsumerClient_12\enumDictionaryFilename = "./enumtype.def"
\ConsumerClient_12\directoryReqFilter = "SERVICE_INFO_FILTER | SERVICE_STATE_FILTER"
\ConsumerClient_12\SourceMirroringMode = "0"
\ConsumerClient_12\useEventQueue = true

I haven't included my RFA.cfg file, because obviously its contents are unique to my environment.

Notice the service name is "UNKNOWN". If you inspect the contents of the directory message more closely, it seems to contain what looks like "stale" data.

Our organisation has an RHS solution as well, and the problem does not manifest there - it only occurs when directly connecting to the Elektron Edge Device.

Because of the architecture of our application and our deployment environment, all clients need to use the same login/Session.

Is the above a bug in RFA? Is there something fundamentally wrong with my use of RFA here?

Thanks in advance!
