Solaris process memory usage increase but not forever

On Solaris 10 I have a multithreaded process with a strange behaviour. It manages complicated C++ structures (RWTVal or RWPtr). These structures are built from data stored in a database (using Pro*C). Each hour the process looks for new informacion in database, builds new structures on memory and it frees older data. But, each time it repeats this procedure, the process memory usage increases several MB (12/16MB). Process's memory usage starts from 100M until near 1,4G. Just to this point, it seems the process has memory leaks. But the strange behaviour is that after this point, the process stops to continue growing up anymore. When I try to look for memory leaks (using Purify tool) the process doesn't grow up and no significant leaks were showed. Did anyone found a similar behaviour or can explain what could be happening?

Hi, thanks for responding
Ja, i guess thats possible, but to do it all one row by row seems ridiculous, and it'll be so time consuming and sluggish surely. I mean, for a months worth of data (which is realistic) thats 44640 individual queries. If push comes to shove, then I'll have to try that for sure.
You can see by the example that I'm saving it to a text file, in csv format. So it needs to be a string array, a cluster won't be of much help I dont think.
The only other way I can think of is to break it up into more manageable chunks...maybe pull each column separately in a for loop and build up a 2D array like that until the spreadsheet storing.
You only do 1 query, but instead of Fetching All (as the Select does) you'll use the cursor to step through the data.
You can use Format to String or Write Spreadsheet fire with doubles.
You can break it down to get the data day by day instead of a full month at once.

What's the recommended setting for "Process memory usage" ("process virtual" in UI) for a 64-bit host on a 64-bit OS?

Hi gurus
In resource based throttling, what's the recommended setting for "Process memory usage" ("process virtual" in the resource based throttling tab of the UI) for a 64-bit host
on a 64-bit Windows OS?
According to MS (http://msdn.microsoft.com/en-us/library/ee308808(v=bts.10).aspx):
"By default, the
Process memory usage throttling threshold is set to 25. If this value is exceeded and the BizTalk process memory usage is more than 300 MB, a throttling condition may occur. On a 32-bit
server, you can increase the Process memory usage value to 50. On a 64-bit server, you can increase this value to 100. This allows for more memory consumption by the BizTalk process before throttling
occurs."
Does this mean that 100 is the recommended setting for a 64-bit host on a 64-bit Windows?
Thanks
Michael Brandt Lassen

Hi Michael,
Recommended setting is the default setting which is 25 .dot.
If your situation is abnormal and you see message delivery throttling state to “4” when the following performance counters are high or if you expect any of you integration
process could have impact on following counters, then you can consider the suggestion by Microsoft. Don’t change the default setting.
High process memory
Process memory usage (MB)
Process memory usage threshold (MB)
You can see these counters under “BizTalk:MessageAgent”
You can gauge these performance counter and its maximum values if have done any regression/performance testing in your test servers. If you have seen these counters having
high values and causing throttling, then you can update the Process memory usage.
Or unexpectedly you’re process high throughput messages in production which is causing these counters to go high and cause throttling, then up can update the Process memory
usage.
The above two cases where I know my expected process usage (by doing performance testing) or suddenly my production server processing has gone high due to unexpected business
hike (or any reasons) which caused throttling, then do changes to default throttling setting.
Just changing the default setting without actual reason could have adverse effect where you end up allocating
more processing capacities but the actual message processing message usage ever is low means you end up investing in underutilised resources.

Sql memory usage increase each time win app runs

Hi,
Sql memory usage increases each time when win app runs. Why does it work like this? Is it normal ?
I restart SQL Server 2012. Only my win app uses SQL server.
First run of winapp.
start memory usage : 211.800 KB
close memory usage: 528.136 KB
Second run of xaf app.
start memory usage : 528.136 KB
close memory usage: 996.844 KB
Third run of xaf app
start memory usage : 996.844 KB
close memory usage: 997.640 KB
Fourth run of xaf app
start memory usage : 997.640 KB
close memory usage: 1.104.864 KB

Hi,
Sql memory usage increases each time when win app runs. Why does it work like this? Is it normal ?
Yes, it is perfectly normal for SQL Server to acquire and hold onto large amounts of memory indefinitely. This memory improves performance by avoiding disk I/O, query plan compilation and costly memory management.
On a dedicated SQL Server you should usually let SQL Server dynamically manage memory. It will release memory if it detects memory pressure. But if you often run other applications on the server than need significant amounts of memory (e.g. IIS,
application services), you may want to set max server memory as suggested.

CPU/Memory Usage increases when loading SWF files in AIR.

Hi,
We face the below mentioned problem. Would be great if someone could help us.
Due to problems with uploading the attachment here, please send a email to the following email-id ([email protected]) and I shall send the attachment in response.
CPU/Memory usage increases drastically while moving the SWC components and loading the SWF Files.
"Problem Description" - On executing the sample application, a window with multiple objects is shown. The loaded SWC components in flex consume too much Memory and CPU cycles. This is visible in TaskManager. On dragging one of the object, CPU / memory usage increases drastically.
"Steps to Reproduce" -
Draggable window is placed at the bottom in the sample application with Text indication.
Drag the indicated window.
"Actual Result" - System's CPU usage increasing drastically around 50% to 60 %.
"Expected Result" - Drastical increase in memory\CPU should not occur.
"Any Workarounds" - No"
Thanks in advance.

You can control your external swf from your main.swf in the following method:
loadswf(clips[0]);
function loadswf(tmp:String):void{
    passedString=tmp;
    ldr= new Loader();
    ldr.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, progressListener);
    ldr.contentLoaderInfo.addEventListener(Event.COMPLETE, swfLoaded);
    ldr.load(new URLRequest(animPath+tmp));
    function progressListener (e:ProgressEvent):void{
        ploader.visible=true;
    function swfLoaded(e:Event):void {
        mcExt = e.target.content as MovieClip;
        ldr.contentLoaderInfo.removeEventListener(Event.COMPLETE, swfLoaded);
        mcExt.addEventListener(Event.ENTER_FRAME,onEnterfn);
        ploader.visible=false;
        addChild(mcExt);
function onEnterfn(e:Event):void{
    var num:int=mcExt.currentFrame;
    switch(passedString){
        case clips[0]:
            if (num==1) mcExt.play();
            if (num==9) {
               mcExt.skipmc.addEventListener(MouseEvent.CLICK,skipfn);
                function skipfn(e:MouseEvent):void{
                    mcExt.stop();
                   mcExt.removeEventListener(Event.ENTER_FRAME,onEnterfn);
                    gotoAndStop("help");
            if (num==mcExt.totalFrames){
               mcExt.removeEventListener(Event.ENTER_FRAME,onEnterfn);
                gotoAndStop("help");
            break;

Solaris 8 memory usage

Is there a tool like McDougal's prtmem that will show accruate (or more accruate) memory usage then vmstat's freemem will show?

tzzhc4 wrote:
prtmem was part of the MEMTOOLS package you just listed, I belive it relies on a kernel module in that package and doesn't work on any of the newer kernel revisions.But it certainly works on 8, right? And that's the OS you were referring to, so I assumed you were thinking of something else.
From that page:
System Requirements:     SPARC/Solaris 2.6
               SPARC/Solaris 7
               SPARC/Solaris 8
               SPARC/Solaris 9
               x86 /Solaris 8
               x86 /Solaris 9
So if that's what you want to use, go for it!
I thought freemem didn't include pages that had an identity, so there could be more memory free then was actually listed in freemem.What do you mean by 'identity'? Most pages are either allocated/reserved by a process (in use) or used by the disk cache. Under Solaris 7 and earlier, both reduced the 'freemem' number. Under 8 and later, only the first one does.

2nd. gen. shuffle volume (on wheel) will increase but not decrease

My 2nd. gen shuffle will increase the volume using the wheel but it will not turn back down using the wheel. to reduce volume you must reset by turning off- then on. I have turned the max vol (using windows computer) both on and off and this does not affect problem. When you reset the volume is about mid point and again you can increase using + wheel but not decrease with -. the other wheel and all other functions are perfect.

Not looking good if you ask me especially since the problem was persistent across two different PCs and the reset utility did not help.

Trying to lock out Solaris 11 non-root users but not working-

Hi,
We are trying to lock out non-root user after 5 unsuccessful login attempts by editing the policy.conf file but it's not working..It's working in the global zone but not in the non-global zones. Is there something else we need to do?
This is Solaris 11 with Solaris 11 NGZs.
kind regards

It works exactly the same way in the global and non global zone cases. This code is 100% userland so it doesn't mater if it is running
in a global or non global zone.
Note that you do need to configure policy.conf in both the global and non global zone.
Are both configured similarly with respect to nameservices ?
Currently we only support lock_after_retries for the local files nameservice.

Why does memory usage increase after RAM upgrade

I upgraded my MBP RAM from 4GB to 8GB. I'm not running any additional applications, so I expected machine's RAM usage to remain the same as it was before upgrade.
However, my RAM usage has increased to 4.6 GB. Why does my machine need more RAM now for the same lot of programs?

3.6.7 Lag, Delay, Memory Leak Checked But Not Fixed?

Well, open a tab, try to open another tab, about 20 seconds of appearing frozen passed.
Okay let's try clicking the first tab again, oh well, another 20 seconds frozen with cursor not even usable.
Okay let's try clicking the url bar, oops, another 20 seconds of delay, and the program is up to 180 megs of memory, that spikes down to 150, then builds again, apparently a new routine is added to "clear" the memory every so often, however, THE MEMORY LEAK ITSELF REMAINS UNTOUCHED.
Maybe Firefox has become so disgustingly bloated with worthless and useless "innovations" that stroke the egos of its developers that, finally, the program is worthless for daily use.
Second Life is a program that's been around for a very long time, and just open firefox, then Second Life. First, you log in to second life wearing the image of the webpage you have open in Firefox. Then you notice that Second Life is lagging endlessly, sometimes with 5 second delays trying to select anything. Close Firefox, and Second Life performs properly. Amazing isn't it?
Memory issue is THE MOST IMPORTANT FIRFOX ISSUE but apparently no one cares, too busy appreciating themselves for some part of the program that was their idea I guess.
Who cares if 3.5 Firefox is the first to have video without a plug in, if, the program is memory leaking like the BP well was leaking oil??
But, as one can see with a memory monitoring program, Firefox now, finally after almost 20 revisions, has a "fix," to lower the amount of memory along some time-line that seems to keep it from accumulating to 500 megs in a matter of minutes, but, WITHOUT ACTUALLY FIXING THE CAUSE OF THE MEMORY LEAK.
I wonder if these volunteers for Firefox are unemployed, and that's why they have time to work on Firefox, their lack of competence the reason they are unemployed, long before this recession.
FIX THE MEMORY LEAK THAT STARTED WITH 3.5 ALREADY! PUT EVERYONE ON THAT INSTEAD OF ANYTHING ELSE!
P.S. My extensions have nothing to do with Firefox's lack luster performance. The issues have existed with or without them installed. Reality: Firefox programmers are busy with head inserted in hindquarters, feeling good about themselves for volunteering, irrespective of coding pure junk. Quality and doing what is right have apparently been thrown out the door, and the message, "a free internet means you get worthless products" the message of Mozilla.org.
== This happened ==
Every time Firefox opened
== version 3.5

same basic idea- ctrl-shift-del (clear everything) and it went from taking >700megs on startup (PC XP,all addins disabled) to ~60megs.
Better wtf is what was stored in that 650+ megs?

Why Loop execution of ActiveX method cause memory usage increase dramatically?

hi,all
I have tried a simple structure as follow:
ActiveX Control is TeeChart Control which is widely used in Delphi
env.
ActiveX Control Ref |------------------------
| |
| ActiveX method |
| |
| |
| |
| i stop->@ |
As the loop execut
ing, memory used by labview increase 4k/second
and several
minute later, it has used up 100M!!
I can confirm that ActiveX Control is Valid cause no problem occure
in VB or Delphi.
I google the web and found that many people have been puzzled by
such problems. Is it a bug in Labview?
Software :
LabView7.0
TeeChart ActiveX Control V5
WinXP
Hardware:
AMD Athlon
256M SDRAM
Any reply be appreciated!

> ActiveX Control is TeeChart Control which is widely used in Delphi
> env.
I like the picture, but couldn't tell if your ActiveX method was
returning other refnum values which it allocated and expected LV to
Close. This is the most likely cause. So, I'd inspect each of the
return values, and if any of them are refnums or are being cast to a
refnum and used as one, be sure it gets Closed. Other things like
arrays should either be converted into LV arrays and released, or if
unwired, they should be released. If you have excluded the problem with
refnums, you might look at the unwired inputs and wire them temporarily
to the edge of a sequence or something just to see if the problem gets
better or worse. Please report anything that you find that
doesn't look
correct.

I got an iPod nano a week ago, and since I installed the CD for the iPod on my computer, iTunes doesn't open. I removed QT and iTunes and the iPod updater and reinstalled them, but to no avail.
I took my computer to the local Apple store and they tried to help me, but again to no avail.
For some reason, iTunes.exe and iTuneshelper.exe are both running as processes when I doubleclick the icon on my desktop, but the physical program doesn't open, thus I am unable to update my iPod and put any music on it.
Anybody come across this problem and know a solution?

First uninstall iTunes and quicktime, scan the system for viruses and then scan for malware using Ewido http://www.ewido.net/en/download/
Disable antivirus and any other security programs you have, download the latest iTunes from www.apple.com and install it.
If this doesn't work try to see if you can open the quicktime program, If you can't install the stand alone version of quicktime to see if it will fix the issue http://www.apple.com/quicktime/download/standalone.html
Also goto the PC makers site and download any patches they may offer revolving around iTunes, alot of PC makers like HP have some models that have issues with iTunes and offer patches to fix it

Shared memory: apache memory usage in solaris 10

Hi people, I have setup a project for the apache userID and set the new equivalent of shmmax for the user via projadd. In apache I crank up StartServers to 100 but the RAM is soon exhausted - apache appears not to use shared memory under solaris 10. Under the same version of apache in solaris 9 I can fire up 100 apache startservers with little RAM usage. Any ideas what can cause this / what else I need to do? Thanks!

a) How or why does solaris choose to share memory
between processes
from the same program invoked multiple times
if that program has not
been specifically coded to use shared memory?Take a look at 'pmap -x' output for a process.
Basically it depend on where the memory comes from. If it's a page loaded from disk (executable, shared library) then the page begins life shared among all programs using the same page. So a small program with lots of shared libraries mapped may have a large memory footprint but have most of it shared.
If the page is written to, then a new copy is created that is no longer shared. If the program requests memory (malloc()), then the heap is grown and it gathers more private (non-shared) page mappings.
Simply: if we run pmap / ipcs we can see a
shared memory reference
for our oracle database and ldap server. There
is no entry for apache.
But the total memory usage is far far less than
all the apache procs'
individual memory totted up (all 100 of them, in
prstat.) So there is
some hidden sharing going on somewhere that
solaris(2.9) is doing,
but not showing in pmap or ipcs. (virtually
no swap is being used.)pmap -x should be showing you exactly which pages are shared and which are not.
b) Under solaris 10, each apache process takes up
precisely the
memory reported in prstat - add up the 100
apache memory details
and you get the total RAM in use. crank up the
number of procs any
more and you get out of memory errors so it
looks like prstat is
pretty good here. The question is - why on
solaris10 is apache not
'shared' but it is on solaris 9? We set up
all the usual project details
for this user, (jn /etc/projects) but I'm
guessing now that these project
tweaks where you explicitly set the shared
memory for a user only take
effect for programs explicitly coded to use
shared memory , e.g. the
oracle database, which correctly shows up a
shared memory reference
in ipcs .
We can fire up thousands of apaches on the 2.9
system without
running out of memory - both machines have the
same ram !
But the binary versions of apache are exactly
the same, and
the config directives are identical.
please tell me that there is something really
simple we have missed!On Solaris 10, do all the pages for one of the apache processes appear private? That would be really, really unusual.

DAX error "Formula is invalid" when updating underlying data, but not changing the formula?

Hello,
first of all: I use the 64-bit versions of Excel 2010 and PowerPivot on Windows Server 2008 R2.
I use this formula to calculate the median of my data:
MINX( FILTER( VALUES( TableName[ColumnName] ),
              CALCULATE( COUNTROWS( TableName ),
                         TableName[ColumnName] <= EARLIER( TableName[ColumnName]
              > COUNTROWS( TableName ) * 0.5 ),
      TableName[ColumnName] )
The data comes from a view on an MS SQL Server and has about 3.5 million rows. With one dataset ("dataset 1"), everything is working out fine and VERY fast ;-). When I change the view on the SQL server to filter for different data ("dataset 2", the result
set still containing about 3.5 million rows) and update the PowerPivot data and then the pivot table, the status bar reads "Executing OLAP query..." and excel.exe utilizes one CPU core at 100% for a long time and its memory usage increases significantly, but
nothing happens. If I interrupt that process by pressing Esc, I get the following error (original German text included):
============================

I have analyzed the two datasets for differences and found the following ones:
Dataset 2 has also negative values in its ColumnName column, dataset 1 does not. Filtering dataset 2 (by changing the view on the SQL server) so that the column contains only positive values does not help.
A displayed column contains text with square brackets in it in dataset 2. Changing the SQL view to replace them with an empty string (replace(column2, '[', '')) does not help.
I do not know what else to try. Can anybody help me? The two datasets are very large, but if anyone can give a recommendation how to export them in a reasonable size, I can make them available.
Best regards
Michael

Hello Javier,
I use a new measure (button "New Measure" in the toolbar or option in the context menu of the table). Here are the data samples:

In both datasets, probability has a range from 0 to 1, both thresholds from -1 to 1. In dataset 1, value has a range from 0 to 1, in dataset 2, it's -1 to 1.
Thanks for your help!

Very high memory usage with Yahoo Mail

After using Yahoo Mail for an hour or so my memory usage increases to a very high level.
Just now, after reading and deleting about 50 e-mails (newsletters etc.) I noticed Firefox 17 running slowly and checked the memory usage in Windows Task Manager (I am using XP) and it was 1.2 Gb. My older laptop only has 2 Gb of RAM. Yahoo Mail was the only thing open at the time.
I never notice this problem with Gmail which I mainly use. However I use Yahoo Mail for quite a few newsletters etc. that are less important and which I only check once a week or so.
I found the following bug report about 3 years old which almost exactly describes my problem.
https://bugzilla.mozilla.org/show_bug.cgi?id=506771
But this report involves a much earlier Firefox version, and at the end it seems to say that the problem was fixed. However it well describes my current issue with Firefox 17, especially the continual increase in memory while using the up/down arrow keys to scroll through Yahoo e-mails.
Is this normal to have to shut down and reopen Firefox every hour or so to clean out the memory? For some reason I only notice this when using Yahoo Mail. After using many other sites and having multiple tabs open for several hours I rarely reach that kind of memory usage. About the highest I've seen with other sites after a couple of hours is 600 Kb which is roughly when I start notice slower response times.
