5213.0. "ELMS AM crashes MCC with ACCVIO" by GIDDAY::COOPER () Thu Jun 17 1993 02:14


Hi,

I have a customer running MCC V1.3 with the ELMS AM and he is intermittently 
having problems with ACCVIOs.

Sometimes when he goes into a bridge or concentrator icon and selects 
something e.g. identifiers he gets and access violation and MCC crashes.

The stack dump looks like:

5SYSTEM-F-ACCVIO, access violation, reason mask=01, virtual address=EA352800, 
PC=0175F767, PSL=03C00000

  Improperly handled condition, image exit forced.

Is this a known problem and is there a fix?

Any help much appreciated.

Thanks,

5213.1check account privsQUIVER::HAROKOPUSFri Jun 18 1993 11:176
    Check to make sure he has log_io and phy_io privs.  When these privs
    aren't enabled the bridge AM and conc AM will crash sometimes instead
    of giving an error message.  This is a known bug in the MCC EA
    routines.

5213.2Checked PrivilegesGIDDAY::COOPERSun Jun 20 1993 22:117
Thanks for the reply. I checked with the customer and he claims he had 
all privileges enabled. I will wait till he has another problem and get
more detail on exactly what he was doing and the account setup.

5213.3Another crashGIDDAY::COOPERWed Jun 23 1993 03:1841
Hi,

The same customer has had another problem. This time he was rearranging 
icons in some of his larger domaIns and clicked on a DECbridge 90 that
was registered as a station. He clicked on the DB90 and pulled down show
identifiers and clicked. He got a crash that looked like:

%SYSTEM-F-ROPRAND, reserved operand fault at PC=80000010, PSL=03C00004

  Improperly handled condition, image exit forced.

This customer seems to have all the good problems. Anyone seen this before?

Any help much appreciated
