Weblogic not releasing threads or memory
Actually, making Weblogic do a thread dump helped us find the issue,
our application did not close its LDAP connection threads in all cases, so
that was why its number of threads kept going up. The thread dump option
is a very useful tool for troubleshooting.

This is "unintended object retention", ie a java version of a memory
leak.
So you have a couple of options.
1. Profile your application and after running your test which reproduces
the problem, and running GC see who is holding refs to objects.
2. Do the same as 1.
3. Do the same as 1.
I suggest Jprobe 2.5.

We are runing Weblogic 4.5.1 on SunOS 5.6, with Solaris_JDK 1.2.1_04 and
we have allocated 512 Meg to the heap. We set the ThreadCount to 90.
The threadcount showing in the TOP utility is growing higher and higher,
it never decreases. It is up to 200 at this point. The resident memory
also seems to keep growing and growing, it is at 445M now.
So it looks like resources do not get released. Does anyone know the
solution to this?
Or is this normal behavior?

Weblogic server does not release the memory after shutdown the weblogic server.
A bit late to the party here but this issue is still live and I can't find anything else on the forum similar to it (apologies if there is).
Photoshop does not seem to re-use memory it just keep allocating new right up to the limit before the prog crashes (same applies to Fireworks) so any batch/script processing of more than a handful of files is impossible.
I am Photoshop via Creative Cloud (so I am always updated to your latest release), Windows 7 64k with 8Mb memory and am using Norton Intenet Security 20.3.1.22 which is updated daily. -
Memory not released on disconnections
Hi,
We are developing a pro*C++ application to connect to an Oracle 8i database running in Windows 2000 . The application will run in HP-UX. When the application try to connect to the database, either the connection fails or successes, a memory segment is allocated to the connection, and even when we do a rollback release before the disconnection, the resources allocated are not released, so the memory allocated to the application grows without a limit (every 60 connections it takes 128 kb).
We´ve tried with a rollback/commit release before every disconnection (depending on the failure or success of the associated processes), analising the tnsnames parameters to avoid any waiting time, increasing the timer period between connection tests, but the memory is not being released after disconnections... any idea about what is happening? why even when the connection with the database is not possible there is any memory allocated to it? how could we release it? do you know how to test that the database/listener are alive so the connection is possible, other than try to connect and examine the possible error messagges?
Thanks a lot!
AnaJim,
I don't think this is ID directly causing a problem, but some other interaction. I'm using 5.0.3 on XP pro SP2 and the exe disappears from processes about 2 or 3 seconds after close.
What version of Windows are you running?

Full garbage collection issue, not releasing/flagging memory
I have the following problem running on a multi-cpu windows server with Java 1.4.2_05 using WebLogic 8.1:
During a lifecyle of the web application (under load, but not to heavy) memory usage seems ok and garbage collection is called regularly. Suddenly, the used heap starts to rize very fast and after a while, even a full garbage collection cylce, does not release any memory anymore.
I am sure that, from our coding, we release memory ok, and normally we should only use about 5 to 10 mb for each user max (with0 normal defnew garbage collections).
I tried changing the garbage collection parameters, but this does not solve the problem. Best scenario was with the concurrent collector and I got this output at +/- the end:

Another strange item is: I maximized the amount of memory it uses to 512m with the Xmx parameter, I am almost sure that that one is used, but it never gets higher than 203M? Does anyone know why this is?
Another strange item: the monitoring in the weblogic code indicates 32MB of usage (relative memory usage seems to be ok, but the quanity indication is just plain wrong) with 15 threads running.
This problem does not exist when using JBoss 4.0.2 or 4.0.3 (standard j2ee settings).
If anyone has an idea or can help me, I would appreciate it very very much. :)Hi ,
Is this issue resolved ?
we are facing same problem.
1. We have checked the CPU and memory utilization everything is normal
2. GC logs showing FULL GC calls continuously
3. After restart the resin server system is working normally.

Weblogic Data source is not releasing connections
Hi All,
Weblogic JDBC data source is not releasing connection until JDBC connection is deleted and created again. Could you please let me know this is a database issue or weblogic jdbc driver issue. We are using weblogic 10.1. Please see the following xml for JDBC driver.
Although maximum connections are set to 300, it stills keeps increasing connections over 300. This issue is resolved only when jdbc data source is deleted and created again.

Edited by: bpenugon on Aug 24, 2010 8:02 AMThe root cause is pinned-to-thread is enabled. When the application finishes using the connection and calls connection.close(), WebLogic Server keeps the connection with the execute thread and does not return it to the connection pool. The connection pool maximum capacity is ignored when pinned-to-thread is enabled. So you saw the number of connections in connection pool keeps increasing over 300.
Set pinned-to-thread to false can solve the problem. -
Self tuning threads are not releasing even though server running fine.
One of the cluster instance is running fine and serving the requests with good response but there self tuning threads are not releasing .I am not seeing any stuck threads in logs and no errors. why threads are not releasing.How we can troubleshoot this issue. May I know what are the cause of this.

OIM 11g using too much memory and not releasing it when shutting down
Hello,
we have a problem with OIM 11g using too much memory (about 5gb) and it's not releasing it at shutdown (4gb still used).
We are using a VM with RedHat Linux 5.6. Originally we had 4gb RAM + 2gb swap file. We installed Admin Server, OAM, OIM and SOA on that machine but quickly realised we couldn't run all 4 programs at once in 6gb. AdminServer could run with 2 other products, but it was a tight fit in memory.
So we increased the RAM to 8gb (still 2gb swap file). But then our problem occured : I start the Admin Server (2.7gb total memory used), then OAM (4.6gb total memory used) and then OIM. After it started the server is now using 9.6gb of memory (~300mb of free memory) ! The problem gets even better : after I shut down everything (OIM, OAM, admin server) the "top" command show that there is still 4gb of memory used even tho nothing else is running on the server ! There is absolutely no other process (other than root stuff) running and no other users connected to the machine. After a reboot, it shows 400mb of memory used. I tried restarting the programs and it did the same thing.
Our intuition is that there might be a memory leak or some bug in OIM that might use up almost all the free memory and it's not releasing it upon shutdown. It might have been there before we increased the memory but have not noticed it since memory was already tight.
Anyone encountered the same problem ? Any idea ? Any suggestion to narrow down the problem ?
Thank youYou can adjust the memory settings for WLS by editing the setSOADomainEnv.sh file that can be found in your /middleware/user_projects/domains/<domain>/bin/ folder. There is an argument called PORT_MEM_ARGS which is used to set your Java memory arguments. This way you can decrease/increase the amount of memory used by each managed server.
I usually type "ps -ef | grep oracle" to see what processes are running by the oracle user. This way the output doesn't get cluttered with root processes.

XML,CLOB AND MEMORY : CONSUMED BUT NOT RELEASED !!!
Hi,
I'm working with XMLGEN Package and XSLT Processor to produce XML Document on Oracle 8.1.7.3 server, I use 9i XML and Java packages.
I'm facing the following BIG MEMORY problem :
Environment : I must generate an XML parsed with an XSL document of 80Mo (nearly 22 000 rows),
as XMLGEN is on DOM parsing method, I extract my XML by 500 Rows and I loop until 22 000 rows. I use DBMS_JOB with jobs who read and execute export each minute.
The algorithme is :
keeprow=22000
while keeprow>0
Create 3 clob (DBMS_LOB Package) : one for XSL Sheet, one for XML and one for result
GetXML (XMLGEN Package)
Transform in XSL (XSL Processor)
Write to disk (UTL_FILE Package)
Free the 3 Clob ((DBMS_LOB Package))
keeprow =keeprow-500
loop
The problem : The process start at 250Mo ot total memory and END at 1000 Mo of used memory and NEVER RELEASE 1 ko of memory.
So often I get a JavaOutOfMemoryError (I've allocated 1Go Ram to my JAVA process).
Any help will be very very appreciated !
My derived problem is 22 000 rows is not enough I've some export of 200 000 rows to do (And I cannot allocate 10 Go of RAM !!!)
Following My PL/SQL Code.
Regards
Fred

******************************Thank you for the info - I had no idea I was puing myself in danger by cutting it so close. Since your post I have moved my iphoto library to an external drive and now have 165 GB of space on my HD. Following this I have 2 questions.
1. Since my available HD space was reduced by the size of the photo download it seems logical that the download is somewhere on my HD still. Is there a place where these photos might be hiding on my HD even though they are not available on the iphoto library?
2. I was able to recover the .jpg files which are fine. I also recovered the .mov files but they have been compromised. I am hoping I can find the originals still on the HD somewhere. If not, do you have any suggestions for recovery methods or programs? I have not used the SD card since the incident so I should be able to attempt another recovery to salvage the .mov files if there is an alternative method/program available.
Thanks again! -

SQL Server Memory Usage Peaks to 95% and its not releasing SQL 2012
We are currently running SQL 2012 64 bit, Lock Pages Enabled, 128 GB. We allocated Max Memory 112000, Min Memory to 0. We have a SQL Maintenace Job which backs up (Full Backup) of our server around 11PM at that time the SQL Server memory peaks to almost
96% even during full business hours we are constantly in the range of 56 to 60% but after 11PM within 10 minutes of the job it peaks to 95 or 96 Percentage and even after the job completes it's not releasing the memory back. I have to manually shut the sql
service and then restart at that time it comes back to normal.
Any suggestions/any help really appreciated.Here are the details Memory is at 96% I still didn't restart...Please any help appreciated...The memory detals is for 24 hours I restarted the service around 11AM before I posted my previous message..

PS Touch Android does not release memory when closed.
I have to force closure with Task Manager on my Samsung Note 2 running JB 4.1. Why and when will it be fixed?
Hi Ignacio,
Sorry for the lack of information - I had typed more complete description, but had trouble posting it.
The app is installed on a Samsung Galaxy Note 2 phone that is running Jellybean 4.1.1.
The only way I can see to exit the application is by using the "back" soft key under the screen on the right. Some apps have an "exit" choice under the "menu" soft key, but that key is not active with PSTouch.
I see the same issue with Google Chrome. The menu key is active with this app, but it does not have an "exit" choice.
With both these apps, I have to go to the "Active Apps" tab of the Task Manager to release memory.
There is one difference with PS Touch. Google Chrome always starts the same way whether or not I release it's memory. With PS Touch, if I release memory after closing with the back key, the next time I start it I get an initial royal blue screen with the PS Touch icon in the middle followed by a second screen with a menu in the middle titled "New Project From". If I exit at that point, it takes two presses of the back key to first close the menu and then exit the program and return to a home screen. If I do not release memory, the next time I start PS Touch, it goes directly to the second screen, but without the "New Project From" menu.
I hope this gives you the information you need.

Photoshop does not release memory after closing document.
When I close a large document Photoshop does not release the memory. If I open another document the program is slow and not resposive. If I close out of Photoshop and restart it then load the other document it is quick and responsive again.
A bit late to the party here but this issue is still live and I can't find anything else on the forum similar to it (apologies if there is).
Photoshop does not seem to re-use memory it just keep allocating new right up to the limit before the prog crashes (same applies to Fireworks) so any batch/script processing of more than a handful of files is impossible.
I am Photoshop via Creative Cloud (so I am always updated to your latest release), Windows 7 64k with 8Mb memory and am using Norton Intenet Security 20.3.1.22 which is updated daily. -
Vector renewed but memory not released
Hi,
Please see the following code:
Vector v = new Vector(10000000);
// from windows task manager, it seems it takes 40 Mb of memory.
// there is a need to do the following after some code
v = new Vector(10000000);
// now the memory taken is around 80 Mb
It would be useful if the program releases the earlier memory of 40 Mb. May be it does not work that way? Any thoughts are welcome.
Regards
Chandra.Thank you all folks. Each suggestion helps me understand vectors and memory in a better way than before. I have noted setting the heap and also the 'clear' function.
When I repeat the code several times, it seems that initially there is an increase in memory up to a certain limit (in my case it is 128 Mb) but there is no increase after that, how many times I repeat the code. (Repeating the code is to find when the out of memory problem occurs). It works okay for now.
Thanks to all again.
Regards
Chandra. -
Interface operator : Memory not released
Hello,
In the interface operator provided by Ni “Full-Featured \ CVI”,
it would seem that the memory is not released correctly.
By adding the
following lines of codes at the end of the hand, one realizes that the
number of block and byte are not to 0.
#ifdef _CVI_DEBUG_
unsigned int
NbByte;
unsigned int NbBlock;
CVIDynamicMemoryInfo (“Fine of the Hand”,
&NbBlock, &NbByte, DYNAMIC_MEMORY_SHOW_ALLOCATED_MEMORY);
#endif
A priori that comes from the function:
errChk
(TS_LoadMenuBarResourceStrings (gMainWindow.engine, GetPanelMenuBar
(gMainWindow.panel), 0, “TSUI_OI_MAIN_PANEL”, errMsg));
In spite of my
research, I do not manage to solve the problem.
Somebody would have it
the solution or then a track to be exploited.
Thank you in advance for
your assistanceHello Dave.
I found this KB for your problem.
I hope it will help you.
Let me know if it's ok for you.
Have a nice day.
Regards.
