5028: ZDSK-EVT-MEMORY-PRESSURE
Insufficient physical memory is available to support all the activity for the processor.
Unconditional Tokens
Cause. The processor didn’t have enough physical memory to support all the primary
disk process activity in it. The disk process reporting the problem rejects requests that
it cannot perform because of the memory problem. All other disk processes in the
processor probably report the same error.
Effect. If memory problems prevent the disk process from performing the requested
operation, the DP2 process reporting the problem rejects requests and reports
file-system error 36. All other DP2 disk processes in the processor probably report the
same error.
Recovery. Free some memory in the processor by doing one or more of the following:

Reduce the cache sizes of the disk process, using the PUP SETCACHE command
(D-series NonStop operating system RVUs), or using the SCF ALTER DISK
commands and specifying the CACHE parameter (G-series and H-series NonStop
operating system RVUs). See the Peripheral Utility Program (PUP) Reference
Manual for information about PUP commands and the SCF Reference Manual for
the Storage Subsystem about SCF commands.

Close files on the volume by stopping the processes that have these files open.
