Pesky bugcheck solved
The bugcheck that we uncovered a number of months back has been resolved by OpenVMS Engineering. I received an e-mail yesterday telling me that the fix would be in patch VMS73_SYS-0700 for OpenVMS 7.3, and patch VMS731_SYS-0400 for OpenVMS 7.3-1.
A recent comment made me realise that I had not posted a footprint for this crash. So here it is. Names of the machine and process obscured for security reasons.
