[Info-vax] Defrag Fails on a Large Disk

[richard.l.dyson at gmail.com]

Hi,

I have an IA64 rx2660 running OpenVMS v8.1-1H1.  Can't upgrade to anything else,
off support.  I have a single spindle disk, 600 GB SAS.  Every time I run Defrag (v3.0) I get this error:

%SYSTEM-W-ACCVIO, access violation, reason mask=!XB, virtual address=!XH, PC=!XH, PS=!XL


Here are the spdisk details:

There are a lot of files on this disk:

$ dir/grand/total/siz=all [...]*.*;*

Grand total of 19534 directories, 7689325 files, 607075030/674749212 blocks

Is this some issue with lack of system resources that Defrag needs when it is running due to the large # of files?  Here are System's UAF system resources:

Any suggestions to try?  Or other info needed?

Thanks,
