MATLAB Crashes During Automated Test

I run an automated test on our company's product. It takes about five hours, during which time MATLAB is connected to many external devices

a) two serial USB connections

b) one GPIB connection, via USB cable and GPIB-USB converter

c) another server running on my computer

d) one LAN connection to a network analyzer

Sometimes, during this scan, MATLAB simply disappears, meaning the program closes, with no error message or warning. The computer does not get stuck, there is no blue screen, etc. I can continue working as usual, and also restart MATLAB if I want. When I restart MATLAB, everything looks normal, except that the Command History does not contain the most recent commands I typed. Additionally, no matlab_crash_dump file is created.

The java.log file is:

Stack Trace:
[0] jmi.dll:void __stdcall mwJavaAbort(void)(0x78f833fc, 1, 0x78fb96dc, 0) + 21 bytes

FAQ: http://matlab.wikia.com/wiki/FAQ#After_installation.2C_MATLAB_crashes_or_gives_an_error_message_when_I_try_to_run_MATLAB.

It says "The Mathworks gives free support for all installation problems, even by telephone and even for the Student Edition. Call them at [phone]. Although the Student Edition normally does not get technical support, it does get support for installation issues."

Huh?

Yeah, that doesn't quite sound right, does it. Basically it means call them. I changed the FAQ to read this way: The causes for crashes are many and complex, and complicated to figure out, especially if you don't have access to the source code. This is why it's best for The Mathworks to work on your crash issue. Call The Mathworks at [phone] and explain to them the circumstances for your crash. Note, this is just if MATLAB itself crashes, not if it's your m-file throwing an error (red text in the command window).
