This article describes the CtxExceptionHandler Dump under C:\ProgramData\Citrix\CDF\Reports.

Instructions

When an unhandled exception occurs in an EXE or DLL that uses the CtxExceptionHandler SDK(the CtxExceptionHandler(64).exe), it will generate a memory dump. 
The memory dump is written to C:\ProgramData\Citrix\CDF\Reports\<process name>\*.dmp on Virtual Delivery Agent(VDA) machine.

The following registry values control the operation of CtxExceptionHandler(64).exe.

For 64-bit processes the registry key is HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\CtxExceptionHandler.
For 32-bit processes the registry key is HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\CtxExceptionHandler.

1. DumpType - REG_DWORD, 1=Mini dump, 2 = Full dump
2. Enabled - REG_DWORD, 1 = Enabled, 0 = Disabled
3. MaxReports - REG_DWORD, Number of dump files to collect

* If you want to avoid this memory dump, you can set 'Enabled' value as 0 to disable it.
