Siebel AOM crashes during CTI hoteling call transfer due to an access violation exception (0xC000000

@UserName}

We are having sporadic Siebel Callcenter Object Manager crashes during call transfers, usually it happens when CTI operators transfer a call to operators which are logged off. We have a hoteling (free seating) configuration.

An operator clicks a CTI toolbar item which calls a command:

[Command:BlindTransferCallToPopupEmployeeVoice]

   CmdChannelOnFocus = "TRUE"

   Description       = "Перевод в 1 шаг"

   DeviceCommand     = "TransferSStep"

   Hidden            = "TRUE"

   Title             = "Blind Transfer"

   Profile           = "Gplus Universal Profile"

   CmdData           = "BlindTransferCallToPopupEmployeeVoice"

   [CmdData:BlindTransferCallToPopupEmployeeVoice]

      AttachContext        = "TRUE"

      Param.CallNotifyText = "Blind transfer from {@UserName}..."

      Param.PhoneNumber    = "[$HotelingPhone(Login Name):Lookup]"

      Param.TSC_TRANSFER   = "TRUE"

      Param.TrackingID     = "{@SelectedWorkItem:DriverWorkTrackID}"

      SelectApplet         = "TSC ACD Transfer Call Applet"

      SelectBusComp        = "Employee"

      SelectBusObj         = "Employee"

      SelectParam          = "TRUE"

      SelectQuerySpec      = "[Login Name] IS NOT NULL"
