83A memory leak following recent patches?

A few days ago, I installed FIBRE V7, RMS V10, SHADOWING V5, SYS V16.

Since then Total committed paging file usage seems to be increasing.

I see that the RMS kit includes changes for global buffers, which we use, and I wonder if anyone else is experiencing a problem?

Re: 83A memory leak following recent patches?

Thanks for the heads up.

What makes you suspect RMS Global buffers?

There is a fix for those as part of the RMS patch kit, but I happened to have worked with the customer experiencing this problem and it has nothing to do with space allocation best I understood it.

When you mention 'increasing' can you be a little more specific?
Compared to what?
How much?
Pages, thousands of pages, millions?
And if it is lots, seemingly in large increments?
(like a global buffer worth ;-)
How Fast? every second? hour? day?
Per image activation? Per file open? Per...?

Perhaps use T4 to fnd a correlation?

If you can nail it down to a process (group) then maybe ANAL/SYS, SET PROC ..., SHOW PROC/RDE
Now use SHOW PROC/RMS=GBH.
You should see "GBH Address:" P2-address values corresponding with each (re)used RDE

Of course there may be other usages in the program.

Re: 83A memory leak following recent patches?

Thanks Hein, I'll see if I can get specifics.

I have had to reboot once since installing the patches because page file was exhausted and had no problems previously.

I had seen a bunch of BASIC "Cannot open file" errors a while before that, but didn't get to the underlying system error.

Peter,
Would probably also be a good idea to create/install a couple of large secondary page files, on some free storage. This would give you some breathing room, (if this is happening quickly or unpredictably)

Yes, thank you.

I doubled the page file size when the reboot became necessary.

Re: 83A memory leak following recent patches?

Peter,

in addition to Dave's advise and doubling the pagefile, please keep in mind that IF you notice pagefile usage growing, you CAN (on the fly) create and install an extra pagefile (as much as the number of SYSGEN specified pagefiles allows).
New pagefiles get used by new processes, so existing processes do not benefit ( Gurus, is this still true in V8.x ? )
Bear in mind, that you need to do this timely!
50 % pagefile use indicates the need to do it NOW, and NOT wait some more minutes (!).

fwiw.

Proost.

Have one on me.
