NOTE
The results of the VMS error handler may be preserved
within the operating system session (for example,
disabling a cache) but not across reboots.
Although the system can recover with cache disabled,
the system performance is degraded because access
time increases as available cache decreases.

Entry Format
The VMS error handler for the kernel can generate six different
entry types, as shown in Table 5–11. All error entry types, with
the exception of correctable ECC memory errors, are logged
immediately.
