Error TheEvent.cpp line 233

I want to add my encounter with this error message, hoping it will help someone who's working on a solution.

On the computer that this happens, I have the following related softwares installed:

- PC: Windows XP Pro version 2002, SP3

- LabVIEW 2009 (with one patch applied)

- TestStand 4.2

- RealTime + FPGA 2009 (patch applied)

- Driver for the high voltage Glassman FL series (1.5KV). There are vi's built to communicate with these power supplies through USB (serial) ports.

- Also have the "NI USB to RS-485" 4-port signal converter

I have seen ' "thEvent.cpp", line 233 ' regularly. In my case, it does not happen when I turn on only one of the above power supplies. It occurred only when I turn on both of the above high voltage power supplies which use two USB ports (maybe they should be daisy chained). TestStand was not started. After sending commands (telegrams) to these power units for a number of times (10 - 20), Labview would fail on one or both units (Property Node (arg 1) in VISA Configure Serial Port (Instr).vi- ...). The error sometimes popped up when shutting down Labview. Other times it appeared during PC shutdown in a reboot attempt.

Powercycling the power supplies or restarting Labview would not clear the problem. My only option is to reboot the PC. My guess is that it's related to the VISA drivers.

Not sure if this is significant but I have been having this problem running a TestStand sequence via a Labview operator interface.  I have eventually narrowed the problem down to three vi's called from the TestStand sequence. One thing all three problem vi's have in common is that they all contain event structures. All three vi's are now re-written without event structures and the problem has dissapeared.

I am also running Labview 2009 and TestStand 4.2

Further to my previous post. The problem only occurrs when event structures are used in labview vi's called in sub sequences or a called sequence. If thoser same vi's are called in the top level sequence then there is no problem. I have re-written the labview vi's so as not to use event structures and the problem has not surfaced in three days of continuous use. Whereas the top level sequence crashed continuously before.

Has anyone figured out a solution to this? I am getting the error "TheEvent.cpp line 236" in my built executable as well. It is the exact same code that WAS working fine in 2009 SP1
