See the error log manual

http://h71000.www7.hp.com/doc/83final/6048/6048pro_contents.html

Do consider reading the system management manuals at

www.hp.com/go/openvms/doc

and getting some training as you appear to be new to the openvms world.

Short answer:

A bug check is a statement that OpenVMS found a condition it didn't like. It protects itself by doing drastic things regarding those conditions.

A BUGCHECK entry tells you important things about your system. But the fact of a BUGCHECK is almost useless without knowing its "flavor" - which will be part of the code name associated with a BUGCHECK.

BUGCHECK comes in two main flavors - those that can crash a task and those that can crash a system. The latter usually relate to a problem in a critical system data structure, which can be caused by any number of hardware and/or software failures.

Bottom line: You need to know the code associated with the bug check.
