We have a MicroVAX II running ELN v2.1; the following section of code is used to communicate with a `home-brew' device driver: (`>>' is our code) >>SEND ( CM_MSG, CM_PORT ); >>WAIT_ANY ( CM_PORT ); >>RECEIVE ( CM_MSG, CM_COMMAND, CM_PORT ); It runs fine, but at random intervals (range: 5sec to many hours) the program stops & prints the message: (`<<' is system response) <<JOB 7, PROCESS 4, PROGRAM GEM4 RAISED EXCEPTION. <<ACCESS VIOLATION, REASON MASK = 00, VIRTUAL ADDRESSS = 00020410 << PC = 001CF85, <<PSL = 03C000A0 and the Edebug program counter points to the first statement following the receive statement above. Any help we can get in helping us to decode the message or to fix the problem would be greatly appreciated (the standard `thanx in advance'). Additionally, I'd like to know whether there is a list of <subject>-gurus handy; I'm having some problems with some other DEC packages on our VAX 11/780 which runs VMS v4.2 (mainly, the things in the new VAXset) & would really appreciate hearing from anyone else in a similar situation.
