Javaw.exe eating memory

I'm running a particular piece of software called Mailloop that appears to use javaw.exe. After about 6 hours I see in Task Manager that javaw.exe has gone from using approximately 50 MB virtual memory to over 500 MB. If I terminate the process, everything drops back to a normal level (software quits as well naturally). I've read on other forums that this can happen w/ javaw.exe, but is there any fix?

How can you say that it is app problem ? The JVM is mature, and fairly well tested. It is unlikely that large bugs like this would be either unfixed, or at lest not "well known".
trouble even for a shorter period.Is there any work
around to find out what is the actual problem ..?A profiler. It is likely that the app is not closing something correctly (a socket, file, etc) or hanging on to objects once it is finished with them.

Memory grows in javaw.exe but not in java.exe process

Hi,
I'm testing some heavy emoticons(most of them are animated). Emoticons are shown in a popmenu, each emoticon is inside a JLabel with borders that are draw on mouse over. These JLabels are in a GridLayout.
The test itself consists in pressing repeatly on a button that opens the popupmenu with emoticons many times.
I noticed that this test, as a webstart app process (javaw.exe), makes the memory grow continously until someone (SO or JVM) thinks its time to free the mem.
As a standalone app process (java.exe), mem does not grow - ok it grow about 3 MB and stabilizes
Is there some good reason for this to happen?
Thanks

Hello,
Metalink says that the OS is ok.
But now i have found a workaround . I used the installer
from the Oracle Designer patch 10.1.2.2 with the products.xml from the Oracle
Developer Suite 10.1.2.0.2. The installation cancels at the end. Doesn't
matter. I continue with the installation of the Oracle Designer patch 10.1.2.2.
The installation is terminating successful, i correct the tnsnames.ora and the
Designer is running.
No award of beauty - but useable as a workaround.

TosOBEX.exe eats up my Memory

Hello,
I'm currently using the Toshiba bluetooth stack, that came with the billionton BT Dongle, to manage my BT connections. The BT manager works fine, but I've noticed that TosOBEX.exe eats up my memory causing my PC to run slow. I figured it's the problem 'cause when I end TosOBEX.exe, my PC speed gets back to normal.
Is this normal? Or did I do something wrong?
Thank you?

Is your bluetooth stack up to date ? If not update it.

In your case I would also check your COM ports. Maybe there is a conflict with an other device.

Javaw.exe - Application Error while running JWS

Hi!
I have been working to change our application to work with JWS.
I seem to have solved all hurdles and the application runs perfectly as we want it on my computer.
It works perfectly well on my Win NT and another Win 2000 machine, but other people have problems.
On the machines my application does not work, they have JWS installed all right and they can run the demo applications without any problem.
They can also run my application some time at random.
The error they keep getting is a
Javaw.exe - Application Error
The instruction at "xxxx" referenced memory at "xxxx", the memory could not be "read".
Has anybody had this problem? Any help is appreciated.
This error does not happen on my NT no matter how many times I try to break it.
Thanks

I Found the problem.
I increased the heap size of the JVm and everything is fine.

Runtime.getFreeMemory -relatively- static, javaw.exe growing.

Hello. I have a J2SE app that I think it is leaking memory. It is mainly a GUI that connects to a DB. Thing is, if I repeatedly call the method getFreeMemory() from this app's runtime, it stays around the same value. Now, if I check the javaw.exe process in Windows' Task Manager, it keeps growing and growing.
So, my question is: which of those two values are usually taken as the real memory usage of an app?
Thanks!

Look at total memory.
Then check you are closing your Statements and ResultSets in finally blocks.

Big problem with 10.1.2.3 (javaw.exe)

Hello all,
On a single machine (WinXp), i have installed IAS 10.1.2.3 and an Oracle 9i Database.
to make our Forms application working in standalone.
As this is connected to the network all work pretty fine, but if i disconnect it, than lot of process javaw.exe are launched and run PC out of memory !
This seems to be in relation with report process as the cmd is :
= C:\oracle\FRHome_1\jdk\jre\bin\javaw -server -cp "C:\oracle\FRHome_1\j2ee\home\lib\ojsp.jar;C:\oracle\FRHome_1\reports\jlib\rwrun.jar;C:\oracle\FRHome_1\jlib\zrclient.jar" -Duser.language=fr -Duser.region=FR -Xmx256M oracle.reports.engine.RWEngine name=rwEng-0 server=rep_lio-xp_frhome1 ORACLE_HOME=C:\oracle\FRHome_1 engineimplclass=oracle.reports.engine.EngineImpl cacheDir=C:\web\cache\ server_ior="C:\DOCUME~1\LIO~1\LOCALS~1\Temp\rep_lio-xp_frhome1_12689643_1207124972762"
Why this append ?
and how can i make it not ? (whithout stoping report engine)
I have made same some times on 10.1.2.0 and dunot have any problems !
Thank's
lionel

re all,
always same problem with 10.1.2.3 with javaw.exe process,
is there a patch for this OAS version or any solution ... cause it's very very very strange and can't find a way to make it work .
Thank's for reply

Javaw.exe is still running when application is closed

The application works fine. when i close the application using "x" at the top of the window the javaw.exe is still running in task manager. javaw.exe is accumulating all memory when i run the again. The same problem occurs when i run the application through jar. Any help is appreciated

If you use
jframe.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
and you close de window, all your applications
running in the JVM will be closed too because System
exit is used. I prefer to use
jframe.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOS
E);
Alejandro H.If you had read the OP, he was complaining that the JVM was still running even though he had closed his application, which meant he wanted to stop the JVM.

I still see javaw.exe in Task Manager after I close app !

javaw.exe seems to like to hang around (45 mb in memory) after I close the app.
I'm running JWS 1.4.2.
I thought maybe it was because I wasn't doing the System.exit(0) on WindowClosed, but that doesn't seem to kill javaw.exe.
Unsolved mystery.

I am having the same problem.
When invoked from JWS, the javaw task does not exit when the app does.
I suspect this may be something related to a still running thread (the app does make use of threads).
If I exit the app prior to the "threading-heavy" logic, all behaves as desired/expected.
However, when the app is invoked from the command line via java or javaw, the app exits as expected, in all cases.
This confounds me.
Looking at the still active threads at the point at which the last window has been closed, it appears the only difference is that when running under JWS is that there is one additional thread ("traceMsgQueueThread", a daemon thread). Otherwise, the number and daemon state of these threads is the same.
Is there something other than a still running thread which could cause a JWS initiated process to remain running after the app has completed?

Javaw.exe has encountered a problem

Has anyone got this message.
"javaw.exe has encountered a problem and needs to close. We are sorry for the inconvenience."
I was trying to debug my java application using eclipse debugger [eclipse 3.1] on windowsXP when i get this message. This message is very random and doesn't occur at any particular instance.
I have done some background research on this and this is not a font's issue as i have read the solution to this problem at some sites.
The error signature gives ModName as jvm.dll.
I am using jre131_06 to run the application and can't use higher version of jre1.4. I have tried using various versions of jsdk131 - but no success.

I tried debugging the application on some other IDE's like netbeans and intellij IDEA , but it gives me the same error, although on Windows 2000 the description of the error changes to --
The instruction at "0x6d4218fx" referenced memory "0x000000041". The memory couldn't be "read".
This error occurs randomly at verious locations, for various memory locations. Some times the error is memorycouldn't be written.
I will appreciate any kind of help or guidance.

Adl.exe eating up 100% CPU (CS5, Windows)

Hi,
In Flash Professional CS5 on Windows 7 (64bit), whenever I test a movie (ctrl+enter) targeted at AIR, the adl.exe process starts eating up 100% of the cpu at intervals, that is:
- adl.exe eats up 100% of the cpu for several seconds
- then back to normal for several seconds
- then eats up 100% of the CPU again for several seconds
and so on.
I see it in the task manager that the process eating up all CPU is adl.exe; obviously the application being tested (and the whole computer) becomes almost unresponsive on CPU peaks.
If I publish the very same test app as an air package, install and run it, it runs fine, with near to 0% cpu consumption, which is normal.
The raise in CPU consumption does not coincide with anything significant happening, it seems just a random (though almost regular in intervals) oscillation, with no apparent cause.
My swf is not very cpu greedy, it is almost idle. I do ctrl+enter and then don't touch anything, just leave it running (which does almost nothing) and the CPU usage goes up and down. I repeat, this does NOT happen if I publish, install and run the AIR application without the ADL debug launcher.
Has anybody run into the same problem?
Is there any fix?
thanks
m.

Hi ,
Would you mind help me with following questions :
1. What is your AIR version? Could you please have a try on our latest AIR build(http://get.adobe.com/air/?promoid=BUIGQ)
2. In Which running mode you encounter this performance issue? In an IDE , or installing it? According to the prior post, matteosistisette met this issue when running it on Flash CS5 with ctrl+enter NOT by installing it after packaging it as an AIR file
3. I tried with winxp on some machines (such as; dell OPTIPLEX 760 and laptop thinkpad :T400) , using adl to launch it .
   Set it to the front application ,and do nothing, the cpu is 20% - 23%
   Minimize the application, and the cup is 0% – 2%
   Do some operations on the app , it is 30% - 70%
   So have you tried on other machines, such as : winxp on PC instead of na Imac, ,and what's the CPU usage? and relevant PC processor and memory info
4.A little confused about the following info you mentioned:
"I speak of the screen following
the name entry, once all transitions have finished and the puzzle has
exploded it's pieces and the main menu is simply sitting idle"
that the main menu sit idle is the expected result/designed by your app, right?
thanks

Javaw.exe crashing

We have a simple JNI call. We suspect that after the jni call returns something goes wrong and we get the windows XP crash dialog (telling us javaw.exe has crashed). Since we load and unload the DLL every time, we can keep using the program for a while but after that we get another message telling us some address cannot be read.
In the C code we have a printf just before we return 0 in the native method (the one defined in the .h file autogenerated .h with javah). So our native code returns correctly before hanging. Where is the crash happening?
The JVM does not crash, there is no error report. I'm clueless.

The only change is that java.exe crashes instead of javaw.exe.
I'm changing the C compiler. Maybe something changes if I use GCC.
The weirdest part is The java application and the native DLL (which is loaded and unloaded every time it is used through a wrapper DLL) can be used many more times after the first crash message and before windows it finally sais there was an error reading some memory address.
Something even weirder, if I use the app and close it normally before it crashes, when I start it again, it crashes at the first attempt to use it.

Javaw.exe

Hi,
Since we have upgraded to SP14, after working for 1/2 hour in XI(mapping and testing), my computer become very slow. If I look at the processes under task manager, I can see that javaw.exe is taking all the memory. What is wrong with SP14? java cache does not get refresh at all!!!
Rgds,
Yves

Hi,
did you monitor the messages in the Audit log and/or SXMB_MONI??
Perhaps there are very much messages send?
Did you check your default.trc log file to see if there are many error messages?
hope it helps,

Javaw.exe using 99% processor

I am a sys admin... Windows 2000. I support a java application. The app is using hyperthreading... I have two physical processors and I was using virtual processors as well (to have four) but I turned that off yesterday - it was only using two anyway based on some monitoring I did with perfmon.
I have a consistent problem with javaw.exe pegging the processor at 98 - 99 %. We have calculation runs that are taking 4+ days to run and should only take several hours.
We started with a Dell 1650. Then tested with a quad processor from Dell on loan (our architecture team decided a dual proc machine - Dell 2650 - should be enough) but now we have two Dell 2650s in place, three 1650s and they all behave the same.
Is there a heap setting or hyperthreading setting somewhere that I can manipulate for better throughput?
We are using Jrun.
thanks.

I'm not an expert on this stuff but I'm if the VM is
not written to use the hyper-threading, it won't be
utilized. I think this is backed up by the fact that
you determined that they were not being used.OK.
type this into a command prompt:
java -versionAnd send what it prints out to the developer asking if
this is the VM he is using.Will do...
Java is very new to me so I'm having trouble
understanding whether the developer is being honest
with me or not about how long the calcs should take.
There's no telling from our perspective what the
differences between your machine and the developer's
(if any) There could be a lot of problems. If you
don't have a lot of RAM the app could be thrashing
(paging memory on and off the hard-disk constantly.)
Or you might just have a slower machine. If this
program is using the network you might have a slower
connection. Who knows?Well... the development environment is also managed by me and it is the same as production and QA. They actually have a slower/smaller machine. The application code of course would be different at various stages in the life cycle but the Java, jrun and OS are consistent (and locked down so changes cannot be made).
I have 1 gig of RAM - and the hard drive is 34 gig, and the dual procs are 3.1 gHz.
Comare the VM and the RAM. Those are your best bets.Did that. We have ruled out hard drive issues, memory issues and network issues.

High CPU Utilization by JAVAW.EXE

Our report server is a Compaq Proliant 2 900MHz CPUs and 1 GB memory running Windows2000 SP4. Database 9.2.0.1 and iAS 9.0.2.0.1. When we are running 3 or 4 reports concurrently, we notice the CPU will spike to 100% and with that the processing time increases terribly. The process that's chewing up the CPU is JAVAW.EXE.
Anybody has seen this before? Appreciate your feedback.
Customer is also using firewall called prism.

Seen a simliar issue on another application.. just out of curiousity are you running McAfee v8 Virus scanner or equiv??... try to disable this and see if the problem goes away... if it does then it may be the vbscript/jsscript checking module causing the issue...
Worth a look??. let me know??
