DWarn 0xECE53844: DestroyPlatformEvent failed with MgErr 42

[royceking]

hello,

recently labview develop environment crashs frequently, but after built as application, running status has been ok for a period (4 days continuously).

sometimes, labview crashed when just a project file was opened and no vi was running.

attached file is just one typical crash report, and part of lvlog.txt inside this report as follows:

most of warnings are Dwarn 0xECE53844.

Any clue will be appreciated.
