If this were windows, I would throw memory leak out there.
I've seen certain SELECT statements in Unidata leak - to the point the
U2 PID eventually dies a very bad death back to the shell.
On windows, we can see this using process explorer.

Sounds like a job for indexing.

You might want to look at splitting out some of those index records, e.g.
where you have 10,000 fields in an index for CRIME, split this into CRIME,
CRIME-1, CRIME-2 etc. with a maximum number of entries per index. Otherwise
you are not going to get efficient storage at those sizes: if

I really like these suggestions and will give it a go.

Does anyone have any real life examples of performance gains from converting
your large file to 64 bit files?
Does anyone have a performance comparison of 64 bit files vs. distributed files.
I wonder if a 4 terabyte file responds better/faster than a distributed/part
file? SELECTs, WRITES,

Thanks to all who made suggestions. I'm definitely going to use some of
them to improve processing.
Good news: Universe is not at fault!
So why did the process just end? Because a background process we run
logs out processes idle for more than 3 hours. To determine idle time
we check the
The who command's interpretation of idle is solely based on terminal
activity: Is there any input coming from the user? type of activity.
Any unix process that does not have terminal i/o will register as idle in
the who output.

Harold,
Is there any reason you don't use the UV command AUTOLOGOUT to time out idle
sessions?
It does what you want already from within UV already (and can be setup
individually or globally for all UV sessions) and doesn't have the problem of
just looking at terminal keyboard input idle
Real Indexing should win - compound key based on wo...@id, index on
word and then traverse keys in Basic (or via a select) ... saves having
to juggle your own key blocks for larger intersects/more popular words

G'day Baker,
Just thinking in the sandbox, with no 4Tb databases to be found, BUT (as
usual) there may be many aspects to the answer
My initial thoughts would be that avoiding running a subroutine to
determine part file for EVERY write and non-sequential READ would
represent a saving per

RE: nailed ports.
After a lot of hair pulling, I solved this problem on Unix but I don't know if
it can be done on Windows and certainly not the same way.
On Unix, UV uses a file named unohist but IIRC, on Windows, it uses the PID as
the port #.
I have a couple of ideas so contact me
Nailing ports on Windows is a critical issue.? IANA port rules specify
well-known and registered ports?ports should NOT be used without registration.?
At a minimum, a good OS would leave them alone at least for requests for
dynamic or random port numbers.? However, Windows will grab ANYTHING
