When VMS crashes, are you getting crash dumps? If not, start by
configuring the system to generate dumps. I recommend testing the
configuration by forcing VMS to crash.

The default crash dump file is SYS$SYSTEM:SYSDUMP.DMP. After a crash,
save a copy of the dump in another file, so it won't be overwritten if the
system crashes again:

$ ANALYZE/CRASH SYS$SYSTEM:SYSDUMP.DMP
SDA> COPY SYS$SYSTEM:<descriptive name>.DMP

Start your investigation with the CLUE CRASH command in SDA:

SDA> CLUE CRASH

If the problem is due to a bug in the device driver, you'll need accurate
compiler listings and linker maps .
