Process memory leak issue solaris 10

I have a process which has a memory leak issue. I ran this process on solaris 9 as well as solaris 10. When i run prstat command i get a different output for two. Funny thing is that memory leak noted in solaris 10 is much more than that in solaris 9 e.g if it is 1 MB in solaris 9 then its 4 MB in solaris 10.
What can be possibly causing this ? Is this related to kernel implementation on diff solaris ?

Memory leak issue with link server between SQL Server 2012 and Oracle

Hi,
We are trying to use the linked server feature with SQL Server 2012 to connect SQL server and Oracle database. We are concerned about the existing memory leak issue. For more context please refer to the link.
http://blogs.msdn.com/b/psssql/archive/2009/09/22/if-you-use-linked-server-queries-you-need-to-read-this.aspx
The above link talks about the issues with SQL Server versions 2005 and 2008, not sure if this is still the case in 2012. I could not find any article that talks about if this issue was fixed by Microsoft in later version.
We know that SQL Server process crashes because of the third-party linked server provider which is loaded inside SQL Server process. If the third-party linked server provider is enabled together with the
Allow inprocess option, the SQL Server process crashes when this third-party linked server experiences internal problems.
We wanted to know if this fixed in SQL Server 2012 ?

So your question is more of a information type or are you really facing OOM issue.
There can be two things for OOM
1. There is bug in SQL Server which is causing the issue which might be fixed in 2012
2. The Linked server provider used to connect to Oracle is not upto date and some patch is missing or more recent version is to be used. Did you made sure that you are using latest version.
What is Oracle version you are trying to connect(9i,10g, R2...)

Is this a memory leak issue ?

We are using Jdev10g + BC4J + Struts + JSP to build our enterprise application,
but when the application running some days in our Application Server(RedHat AS3-86, with 4GB RAM), the memory consumed is serious ! we doubt and worry
about maybe our application suffer the memory leak problem, so we want to know have the command to find out whether our application caused the memory leak
issue and which program is the major murderer for memory.
In EM console , the memory utilization chart have big memory consumed in "other" legend ? the "other" legend is mean what ? I cannot find the consumer process in system level through ps command ? it seems disapear ! but after I reboot the server , the "other" legend is clear !

The second scenario is, as we perform some deployment activity on 10g, the memory usage chart shows a sharp consumption of memory about 1.5GB .the loss memory almost be display in "other" legend chart !
Please give us some advice , thanks in advance

PGA memory Leak issue along with TNS: listener could not hand off client connection

Hi,
We have two Oracle Database instances in a 32 bit Standard Edition Windows OS machine with 3 GB RAM : 1) 1525 MB (SGA+PGA) 2) 515 MB (SGA+PGA)
Recently we upgraded the RAM from 3 GB to 4 GB. Subsequently we upgraded the SGA + PGA of the 2nd instance to 771 MB.
This has resulted into PGA memory leak issue reported in the alert log file and trace file.
Reverting back the SGA+PGA size to 515 MB solved the issue.
Is this issue related to Address Windowing Extension (AWE)?
Is the reason related to Total memory for all the cumulative Oracle instance should be < 2GB.
How to solve this?

There may be something fixed in the patch that gives the error rather than mysterious hangs. I would prefer that, myself. There may be something in the patch that changes how Oracle allocates user, system and program areas.
At some point you spend more trying to limp things along in a growing environment than simply upgrading. 32 bit environments these days is an indicator that management is figuring some false economies. But that's their prerogative.
The PGA can be affected by many things, not least of which is how the application uses it. Much has been written about it, my own experience has been more is used than most people say. But that is probably just my app. Note there are different ways to set it, and a parameter with "target" in it might not be a hard limit. Different execution plans for the same code may use different amounts of memory - there can even be situations where forcing some code to use a sort area instead, or even forcing more operations to disk, can free up more pga for everyone else. It depends. But that's why I look at multi-pass operations in dbconsole.

Is the above correct? If so, you are not even close to having the
latest patches. (NW65SP8, not SP6). Adding late tcp and winsock
patched to SP6 would probably cause problems.
If you look over the abend messages, and some of them refer to an LSL
component, it's very likely you need the wsock6o patch. (Check tip #1
at the URL below).
If you just typo'd the patch, and you are at sp8, at least try clearing
the cache. Unload proxy, load proxy -cc.

Memory leak issue on Blackberry Torch 9860

I own a Blackberry Torch 9860 Os 7.0 Bundle 1465 for the last 5 months
Previously I had Blackberry Curve 9300 which I had upgraded to OS 6.0. It had memory leak issues wherein my application memory would gradually dropdown to merely KBs within a few days and I had to reboot it to restore the same.
When I purchased Torch 9860, I migrated my device settings from Curve to Torch using the Desktop Manager. I face the same memory leak issues in this new device as well. I have 3 email accounts configured on my device and some social networking applications which include facebook, twitter, and some messengers. I usually delete my emails and keep only a few useful mails for reference. Still I am facing this issue wherein I have to reboot my device to restore the application memory. It starts from 152 Mb and usually dropsdown to merely Kilobytes of memory. The phone freezes for around 1-2 minutes sometimes when I am on call, or accessing my contacts.
Also to let you know that I have a 8GB memory card on my phone which has around 1.6 GB free space. I have disabled Compression on my memory card as well.
Please advise as I am having a hard time using this time this way.
Regards,
Abhinav Sharma
Thanks and regards,
Abhinav Sharma

I have the almost same problem when i run the phone gap app on the 9800 torch OS 6 than this build of 1.2 MB takes the memory of 40 MB at run time and the device gives the low memory message and close the app forcefully.
In my app phone gap is using 3-4 html pages and java script .
And when i navigate on these pages it gives this message of memory low.
Please help me to out of this .
And please suggest if any professional help in this
Thanks\\\

What is the best way to deal with memory leak issue in sql server 2008 R2

What is the best way to deal with memory leak issue in sql server 2008 R2.

What is the best way to deal with memory leak issue in sql server 2008 R2.
I have heard of memory leak in OS that too because of some external application or rouge drivers SQL server 2008 R2 if patched to latest SP and CU ( may be if required) does not leaks memory.
Are you in opinion that since SQL is taking lot of memory and then not releasing it is a memory leak.If so this is not a memory leak but default behavior .You need to set proper value for max server memory in sp_configure to limit buffer pool usage.However
sql can take more memory from outside buffer pool if linked server ,CLR,extended stored procs XML are heavily utilized
Any specific issue you are facing

Memory Leak issues

Hello. I am having an issue with Flash 9 and wasnt sure if
this needed to be posted in here or general. I figured that I would
need some kind of code to fix this so I posted it in here.
This is my issue..the typical dreaded memory leak problem.
The project looks very similar to this:
We have, say, 100 individual images in the library. Each
image is an 800x600 jpg file. We create a layer and put each image
on a frame. About every so many frames, (lets say frame 33 or frame
66) we stop at that point and ask a question and wait for some kind
of response from the user. If its the correct response, we continue
on, if not, we just repeat the question till they get the answer
correctly. There are also fscommands that send out to an external
application if the user clicked the correct or incorrect answer at
these points.
However, this is causing a rather massive memory leak. I was
wondering if there is a solution either by code or we are just
doing something wrong, to help fix our memory leak issue. Some
files in our projects are small enough to not notice it but we have
one particular file that is around 500 frames of animation and you
can imagine how hungry flash got with this one.
Any suggestions?

Lots of ideas:
First thing? Check the File Free at Options > Status, what is the number at File Free? Now, remove the battery of your device, hold a minute, replace and reboot. What is the File Free now?

Memory Leak issue 1.5.4.59.40-no-jre jdk1.6.0_12 jre6

Me and 2 other develops have been using SQL developer since it was created but we are getting really frustrated with the memory leaks we are experencing.
We will start up sql developer and if we just leave it alone within a couple hours it will have taken up 650Megs of ram and be completely locked up. If we are working in sql developer the time can be even faster till it lockups up. We have been experencing the issue for very long time but seems to have gotten worse in the last to updates.
I have tried to search the web and form for information to the memory problem to no avail. We are running oracle 10g and windows XP with 2gigs of ram.
Can some one point me to some information or have any idea what is going on?
Edit--
I just realized that I was not using the latest version that I have downloaded. Trying sqldeveloper-1.5.4.59.40-no-jre will advise as to results.
Edited by: ObeTheDuck on Mar 17, 2009 8:47 AM
2nd Edit--
1.5.4.59.40-no-jre has the same issue. 2hrs and it has locked up and is no longer listed as a running app and can only be seen under the process thread in windows task manager with 50% CPU use on a dual-core cpu and 626megs ram being used. Have to kill and restart ... <sigh>
Edited by: ObeTheDuck on Mar 17, 2009 10:45 AM

Thanks for the info so far....
We really do like sql developer as a tool and has been execeding helpful and useful as our development tool.
I am proud to say we have been using it since the 2nd month is was available and have been encourged and happy with most of the improvements.
I am looking forward to trying the modeling tool soon.
If I can get back to having a stable work enviorment for a work day that will be fine for now. It's just been reduced down to 2hrs which is a bit much.
Anyway...
1. We don't have any in house extentions that we need. I am speaking of the one that come bundled with the tool. Or at least I thought that they came bundled.
Several are migration tools which we don't need. One is TenTime tool which I don't think we need.
Last is the versioning extention, this sounds like something we want to use, but stability is more important at the moment. So unchecked they have all been.
2. Sue you asked about a clean install. Is that simply an unpacking a new folder copy and then not migrate settings when running?
3. I will be glad to uninstall java a switch to different version of the jdk which one is consider to be the most stable atm?
Thanks,
Obe

Memory leak in solaris 9

Hi ,
I have Oracle9i database running on Solaris 9. After every 6 days my solaris box went out of space although its a test box and there is no activity on the system. Why the hell it takes all the ram and swap space when there is no activity on the system except Oracle Instance is running with no user connection. What process are running in the background that takes all the memory and i have to restart this box every week. IS THERE ANT PATCH OF MEMORY LEAK FOR SOLARIS9?. I am not a solaris administrator and i have to fix this problem before moving my system to production. I would really appreciate your help.
Thanks.

Hi ,
I have Oracle9i database running on Solaris 9. AfterI have had for some months been running oracle 9i (and 8i) under solaris 9. There have been no problems and the server has been stable.
It sounds like you may have misconfigured the solaris kernel. It also sounds like your SGA is too large to fit in memory.
So I guess the first step would be to check the SGA and then the /etc/system file.
Here is what mine looks like for example:

Memory leak issues persist in Safari 6.0.5 (it's about time that Apple actually fixed this)

Safari has been notorious for its memory leaks for years, as I'm sure many of you know. I stopped using Safari as my main browser in 2010 or so, and I instead began to use Chrome. However, I recently had to use Safari to access some webpages, and I neglected to quit out of it. A few hours later, my computer slowed to a complete crawl. I was confused, because my computer never slows down to such a crawl, so I went into Activity Monitor to find the 'Safari Web Content' process using all of my available RAM, which was nearly 6 GB. Needless to say, Safari was force quit after that. I've heard that some plugins will cause this, but Flash was my only active plugin. Flash is, indeed, a heaping pile of crap that will readily eat resources as it sees fit- but this never happens to me in Chrome, and I use Flash all of the time n Chrome. This was after it had been sitting idle for quite some time, and I imagine that it would have used more RAM if it could.

Using 6.0.5 here without any of those issues ...
Regardless of whether Flash is being used, from your Safari menu bar click Help > Installed Plug-ins.
Try troubleshooting extensions and third party plug-ins.
From your Safari menu bar click Safari > Preferences then select the Extensions tab. Turn that off if there are any installed. Quit and relaunch Safari to test. If that helped, turn extensions back on then uninstall one a time to test.
If it's not an extensions issue, try troubleshooting third party plug-ins.
Back to Safari > Preferences. This time select the Security tab. Deselect: Allow all other plug-ins. Quit and relaunch Safari to test.
If that made a difference, instructions for troubleshooting plugins here.
my computer slowed to a complete crawl.
Checked to see exactly how much space is available ??
Click your Apple menu icon top left in your screen. From the drop down menu click About This Mac > More Info > Storage
Make sure there's at least 15% free disk space.
Checked the startup disk lately?
Launch Disk Utility located in HD > Applications > Utilities
Select the startup disk on the left then select the First Aid tab.
Click: Verify Disk (not Verify Disk Permissions)
If the disk needs repairing, restart your Mac while holding down the Command + R keys. From there you can access the built in utilities in OS X Recovery to repair the startup disk.

OBIEE 11.1.1.5 Memory Leak issues

Hardware: 64 bit Red Hat Linux Enterprise server 5.2(Tikanga)
Software: OBIEE 11.1.1.5 64 bit
Issue: The memory usage on the server slowly creeps up and occupies almost all of the available memory, then starts swapping.
In our case we have a 48GB RAM 2CPU Linux box on which OBIEE 11.1.1.5 was installed and once we startup Weblogic Server, NodeManager, Managed Server, and OPMN, the memory usage starts at ~4GB and slowly creeps up to ~45GB. The processes do not release the memory back even after shutting down all the services (OPMN, Managed Server, Weblogic Server and Node Manager).
The memory is released only after the Linux box is rebooted.
We have the same software on different boxes which have 8GB RAM and the behavior is same there too. It occupies all of 8GB RAM and then swaps over another 4GB space. Is there a software leak with OBIEE 11.1.1.5 or is it a configuration issue?
We found similar issues reported in forums at Memory Leak on OBIEE webserver 11G (linux version) But there was no resolution.

All,
We're having a similar issue, or at least we think we are on our 64-bit VM Windows environment, running OBIEE 11.1.1.3. Our PROD environment was OS level patched last Tuesday and rebooted, and now it's super slow and using way more RAM than before. Even if we reboot the server, our Managed server (bi_server1) is not working properly. Basically in DEV the Admin and Managed servers are using around 900 MB or RAM, in our PROD env that isn't working properly, the Admin server seems fine at about 900 MB of RAM, but our Managed server is up around 1.4 GB and now taking about 45 minutes to start instead of around 6. We also logged an SR about a week ago to no avail so far, and as you said, it's been going back and forth with the OBIEE and WebLogic teams. If anyone knows anything about this it would be great to hear it!
Thanks,
Josh

Finding Process Memory Leak?

I have been tracking down memory leaks in a Java server-based application. I recently ran the application for several hours, and monitored memory usage with both JConsole and the Unix �top� command. I encountered some behaviors that I don�t understand.
With JConsole, I observed that the heap memory usage was fairly constant over time. The Code Cache space, however, gradually increased in size over the life of the test. I expected some increase as additional methods in the application were executed, but it seems that eventually the rate of increase would level out. It did not. Any ideas why that might happen?
The resident memory (as reported by top) increased significantly over the life of the test. Using pmap and jmap, I was able to determine that the heap space was increasing (even though JConsole reported that the heap was constant.) So, it seems as though the heap usage of the application is constant, but the heap usage of the process is still growing? I am using Java HotSpot VM for Solaris (1.6.0-b105).
Any suggestions or insight would be appreciated.

I'm not sure exactly what you're saying, but it sounds like this:
A tool that's monitoring the VM says the memory used by your objects is not increasing, but other tools say the memory the VM has taken from the OS is increasing.
Is that the case? If not, nevermind--I've misunderstood.
If that is the case, then it's totally expected. The VM doesn't usually give memory back to the OS. If it hasn't used up the amount specified by -Xmx (or the default if you didn't specify -Xmx), it's free to just keep grabbing memory from the OS, rather than running a full GC to reclaim memory that it has used for objects but that is no longer reachable.

Tuxedo Memory Leak Issue (Tuxedo 8.1 - Windows Server 2003)

Hi
We are running tuxedo 8.1, 32 bit with patch level 258 in our windows server 2003 based production environment. We are currently facing an issue where the memory usage of machine slowly keeps on going higher and higher eventually resulting in “Memory Allocation Failure” to tuxedo servers. We then have to do a complete restart of tuxedo which stabilizes the system for other few days.
We have been analyzing the our source code in development/test environment using different tools like a customized Alzheimer tool and IBM purify but both tools reported no memory leaks. We then developed a test tuxedo server exposing a tuxedo service which simply allocates a memory to a response buffer and then returns the response buffer. I then configured tuxedo queue with same name “MEMTEST3” and configured a TMQForward server to call this “MEMTEST3” service every time a message is en-queued to the MEMTEST3 queue.
unsigned long _LIBENTRY ulTPAlloc(FBFR32 **ppc, long size)
unsigned long ulRes = MSG_SUCCESS_c;
ppc = (FBFR32 ) tpalloc("FML32", (char *) 0, size);
if (*ppc == (FBFR32 *) 0) {
vLogMessage(hGetLogHandle(), MSG_MEM_ALLOC_ERR_c, (char *) 0, (Event_t *) 0,
BM_NOSUPPRESS_c, size);
ulRes = MSG_MEM_ALLOC_ERR_c;
return (ulRes);
/*==============================================================================
Service MEMTEST2
==============================================================================*/
void MEMTEST3(TPSVCINFO *pRequest)
FBFR32 *pFmlResponse = NULL;
FBFR32 *pFml = NULL;
unsigned long ulRes = MSG_SUCCESS_c;
unsigned long ulActionCode = 0;
int iExitValue = 0;
long lTpurcode = 0;
FBFR32 *pFmlNULL = NULL;
userlog("Starting MEMTEST3 service.");
if (pRequest == NULL || pRequest->data == NULL)
vLogMessage(hGetLogHandle(), MSG_API_ARGS_ERR_c, NULL, NULL, BM_NOSUPPRESS_c);
ulRes = MSG_API_ARGS_ERR_c;
else
pFml = (FBFR32 *) pRequest->data;
userlog("MEMTEST3: GET THE MEM");
ulRes = ulTPAlloc(&pFmlResponse, 1024);
userlog("Ending MEMTEST3 service.");
tpreturn( iExitValue, lTpurcode, ( char * ) pFmlResponse , 0L, 0L );
While I was en-queuing the messages to the queue, I kept on monitoring the memory usage of the server hosting the service. What I observed was that I saw an initial hike in the usage of memory of the server followed by small jumps in memory increase. I kept on monitoring the server for a long time and the memory was never returned. What I suspect is that there is memory leak in tuxedo TMQforward process as it never released the memory allocated in the service.
Can anyone help how this situation can be avoided ?
Kind Regards,
Asim

Hi Todd,
Also as well as my previous question, I also found your reply to another user posting something similar at Re: Memory leaks in Tuxedo libraries
You mention that:
In general Tuxedo will free anything it allocates, although there are cases where memory is allocated and not freed because:
+1) it is one time or a fixed number of times allocations that will not continue to grow, and freeing up the memory just before exiting isn't of any benefit.+
+2) the memory is under Tuxedo's memory management functions where we manage our own look aside lists to provide better buffer allocation performance and again freeing these before process termination is of little benefit.+
Our code does only issue TPALLOC once and then a TPRETURN - could point (1) of your comment above also be something of concern to us, where we would observe a continuous growth of memory usage?
I know it may sound like a stupid question but do we need to run our code 20,000 times before memory gets freed?
Kind Regards,
Asim

Memory Leak Issue in OBIEE 11g

Hi,
We have OBIEE 11.1.1.5 installed on a 32-bit Windows Server. We had almost 10GB of free space yesterday, but after a few users logged in, the free space started coming down until we were left with no space at all.
Since then we have removed all the files that we could and created more and more space, but OBIEE seems to be eating it all up. I have seen a few posts for such issues with the Linux Systems. Has anyone faced this with windows? Also, is there any solution for this.
Thanks,
Naman

Hi Naman,
Oracle has provided set of patches to avoid memory leaks.
1) For memory leak with OPMN, apply the following patches:
Patch:12920592: OPMN HAS MEMORY LEAK
Patch:12989751: OPMN MEMORY STILL GAINS AFTER APPLYING PATCH#12920592
2) For the Presentation Server (sawserver) issue, apply the patch:
Patch:13102881: DATALAYOUT METADATA IMPLEMENTATION HEAP INTENSIVE
