Firefox 6.0 has memory leak
Firefox 6.0 (release) has a memory leak.
Tested with 5 windows and 43 pages loaded and left overnight, it crashed after several hours. Able to fully repro this every time.
I left it for 10 mins after all pages loaded. I opened Task Manager and I can see the Memory (Private Working Set) increasing every few seconds.
Well I'm using 7 beta and my memory usage is just short of 600,000k with plugin container using another 220,000k. There is a massive problem with this!

I typically keep many windows with several tabs open. It is possible that this causes more crashes since the number of pages multiplies any effect most users with less pages/tabs would experience. I have been having problems with Firefox crashing Using the windows task manager I have looked into this issue monitoring lots of variables. Bottom line the crash is caused by increasing memory usage possibly caused by the flash add on which is doing many IO reads on at least one offending page/tab. Could some sites be using flash to read from my disk without permission and there is a memory leak in either flash of the code the sites uses? I have searched the web for a task manager like add-on for Firefox tabs that would allow me to determine the offending page/tab/add-on/extension. It seems like a great idea which has not been implemented. Since I am a developer I would be happy to implement, but would like some guidance since my knowledge of your product is only at the user level.
There is currently about:memory page which is being actively developed. A "task manager"of sorts is also in the works AFAIK. If you want to help out, your best bet is to find the applicable bug in Bugzilla. If you have the coding skills I can help get you in touch with a mentor - just let me know.

Pro*c multithreaded application has memory leak
Hi there,
I posted this message a week ago in OCI section, nobody answer me.
I am really curious if my application has a bug or the pro*c has a bug.
Anyone can compile the sample code and test it easily.
I made multithreaded application which queries dynamic SQL, it works.
But the memory leaks when i query the SQL statement.
The more memory leaks, the more i query the SQL statement, even same SQL
statement.
I check it with top, shell command.
My machine is SUN E450, Solaris 8. Oracle 9.2.0.1
Compiler : gcc (GCC) 3.2.2
I changed source code which is from
$(ORACLE_HOME)/precomp/demo/proc/sample10.pc
the sample10 doesn't need to be multithreaded. But i think it has to work
correctly if i changed it to multithreaded application.
the make file and source code will be placed below.
I have to figure out the problem.
Please help
Thanks in advance,

Sample Program 10: Dynamic SQL Method 4
This program connects you to ORACLE using your username and
password, then prompts you for a SQL statement. You can enter
any legal SQL statement. Use regular SQL syntax, not embedded SQL.
Your statement will be processed. If it is a query, the rows
fetched are displayed.
You can enter multi-line statements. The limit is 1023 characters.
This sample program only processes up to MAX_ITEMS bind variables and
MAX_ITEMS select-list items. MAX_ITEMS is #defined to be 40.

sqlnul() is used to reset the high-order bit of
the datatype and to check whether the column

CHAR datatypes have length, but zero precision and
scale. The length is defined at CREATE time.
NUMBER datatypes have precision and scale only if
defined at CREATE time. If the column
definition was just NUMBER, the precision
and scale are zero, and you must allocate
the required maximum length.
DATE datatypes return a length of 7 if the default
format is used. This should be increased to
9 to store the actual date character string.
If you use the TO_CHAR function, the maximum
length could be 75, but will probably be less
(you can see the effects of this in SQL*Plus).
ROWID datatype always returns a fixed length of 18 if
coerced to CHAR.
LONG and

it is 240 characters.

Word 2011 has memory leak after applying 10.8.1 update
Word started crashing on me recently, it occurs every 8 to 10 minutes when i am working with a large documents. I looked around at the forums and tried all the "Verify Disk Permissions", re-installing, removing normal.dot and word preferences and creating new users. None of these work. I opened Activity monitor and witnessed the memory grow rapidly without any activity in word (The larger the document, the quicker it would rise) from 0-1.5 Gb in around 10 minutes - High CPU is also presentduring this memory leak. When the memory reaches the limit of the available system memory (usually around 1.6G), word crashes.
I tested the same documents on a few other similar computers (macbook and another imac) they did not have the issue, memory remained steady for long periods of time. I check the software versions of the computers and Word was all the same (14.2.3) however OS X was only 10.8 on the working computers where as the failing computer was 10.8.1.
I confirmed the error by updating both of the other computers to 10.8.1, now all computers exhibit the memory leak.
Anyone got any ideas?Update Soundflower to the most recent version. You have an unsupported edition. http://code.google.com/p/soundflower/downloads/detail?name=Soundflower-1.6.6b.dm g&can=2&q=

Querying BOE security - getObjectPrincipals() has memory leak?
Hi,
I am querying the BOBJ Enterprise security and noticed that when I introduce the getObjectPrincipals() method in my code, my program consumes a great deal of additional memory, and will eventually fail due to insufficient heap space as the code iterates through the reports. The issue does seem to be tied to specifically this method, as the memory is handled fine with everything else the same. Is there a known memory leak with this method? I am currently testing against XI R2 SP2 and noticed in release notes for SP5 there was a documented memory leak with a similiar method in the COM SDK - getAnyPrincipals().
Can anyone shed any light on this? I can provide code samples too if need be...
Thanks!Thanks for the responses guys.
Ruben - I did try to use remove() for both of my iterators in use (the first of which contains all principals who have rights for the given InfoObject, and the 2nd contains all of the explicit security rights for the principal) - this unfortunately didn't have any affect on the memory usage. What I tried was as follows:
ISecurityInfo objSecurityInfo = boInfoObject.getSecurityInfo();
IObjectPrincipals objPrincipals = objSecurityInfo.getObjectPrincipals(); //THIS I BELIEVE TO HAVE MEMORY LEAK
Iterator objPrincipalIterator = objPrincipals.iterator();
//retrieve rights applied to object
while (objPrincipalIterator.hasNext())
...get security Role information for each principal
//now get explicit rights information
ISecurityRights objPrincipalExpRights = objPrincipal.getRights();
Iterator objPrincipalExpRightsIterator = objPrincipalExpRights.iterator();
while (objPrincipalExpRightsIterator.hasNext()
..process explicit rights
objPrincipalExpRightsIterator.remove();
obPrincipalIterator.remove();
Ted,
I was already batching the # of InfoObjects to retrieve security information for, but just to be sure I greatly decreased this number and did not see any improvement in memory usage. I actually worked a case with SAP on this question, and they confirmed there was a memory leak with the getObjectPrincipals() method. They confirmed this was fixed for XI R2 in SP5 for the .Net and COM SDKs, but not for Java. Is there anything else I can try? Using getObjectPrincipals(1) for only explicit rights works great as far as memory consumption, but only exposes users with custom roles and I need to retrieve principals with any type of role.
Thanks! -
Firefox Crashes computer with Memory Leak
When I'm viewing a chain of FLV (flash) videos on the web, if I don't close and reopen the browser regularly, it BLUE SCREENS my laptop.... well not blue screens, as much as it forces a Memory Purge then a full shutdown... so .. Black Screens?
This isn't good for my computer, and I've isolated the solo cause of this incident to Firefox itself. (tested with no plugins etc..)Awww.. poodles.. looks like it duplicated itself somehow.. the request that is...

Firefox 27 memory leak (/questions/978195)
I already did this, sorry , but now I include the automated information.....
More than 6GB in 3 hours (MacOSX 10.7.5, 16Gb RAM)
(No time personally to look at this but, I have tagged it as escalate)I will make a quick comment, but am unlikely to get back to this again before the weekend.
First do not think we are ignoring this or saying it is not a problem. It is a case of it is something often difficult to pin down and must initially be checked and compared with Firefox in a clean configuration, and using memory figures from the Firefox's reporter about:memory.
If you can ramp up memory usage to 6GB in only 3 hours at least it should be relatively easy to demonstrate whether or not something prevents that from happening.

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,
NamanHi 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

Memory Leak Issue for Adobe Access iOS API
Hi,
We are trying to develop an iOS app (with ARC enabled) using Adobe Acces API 4.0 and we have identified that the function [drmManager createDRMSession] has memory leak.
DRMSESSION = [drmManager createDRMSession:METADATA playlist:PLAYLIST error:nil complete:^() {}];
We are using:
DRMSESSION -> weak
METADATA ->strong (as need to share within object)
PLAYLIST ->strong (as need to share within object)
After calling this function, the object is unable to dealloc and most of the leaking object related to networking (such as CFNetwork...)
Is this a known issue for the Adobe Access iOS API or we are missing some key steps.
Any suggestions is appreciated. Thanks in advance.ans0600, sorry about that, I read Hiroshi's forward too quickly. I've done a little digging and have come up with two work-arounds:
Create a file with ARC disabled to translate the returned object to be an autorelease
declare the returned DRMSession as __unsafe_unretained and use CFRelease, as noted on stackexchange
In the future we may change this method to return an autoreleased object to avoid this issue. Let us know if you have any further questions! -
Memory leak with File Write.vi
Hi All,
I am trying to save a big data cluster, which includes images, into a data log file. The vis I use are: New File.vi, Write File.vi, Close File.vi.
The problem is Write File.vi has memory leak when the data cluster includes images .
Anyone sees similar case? Any solution?
Thanks.
AiqiuAiqiu,
I am glad you found out about flattening your image to a string. I was about to post and say that you probably didn't want to save the IMAQ image reference to a file, because after you closed the image in memory, there wouldn't be anything for the IMAQ image reference to point to. You are correct to flatten the image to a string. Below is a link to a document which discusses doing this to communicate over datasocket, but the processes of flattening the image to a string is the same regardless of whether or not you are sending the image across a datasocket connection or saving to a file.
Transfering Images with DataSocket
As for the memory leak. I am pretty sure that if you passed all of the IMAQ Image references created in the "Image Init Buffer.vi" subVI and then closed each reference individually, that the memory leak would probably go away.

SQL Server 2012- Memory Leak Issue
Team,
We are running a Mission Critical Application on SQL Server 2012 SP2(11.0.5058) which is configured on Always ON Synchronous mode. Offlate due to heavy development work, Application team have come up with stating memory issues. I have analysed all the areas
and everything looks normal. Please suggest if we have to patch the latest CU4 for SQL Server 2012 SP2.
The checks were performed on the below areas:
- Errorlog, System Logs - No errors reported.
- There are close to 8 Databases hosted on the instances which are all configured for AlwaysON. SQL Server is running on VM Infrastructure and the total physical memory allocated is 96GB out of which SQL is capped for 92GB.
-The Page Life Expectancy is healthy and is showing a greater number. There are no Signal waits either or pending memory grants.
- The writes are more than reads for one of the databases which is flagged with application team. There are no blockings & Deadlocks.
Please suggest me the future course of action and your inputs are much appreciated.
Best Regards,
SharathActual issue is- Application team have reported a memory leak and their builds have significantly slowed down. They suspect that its Database memory leak. However I have verified from database end and gave the above inputs.
The AOAGs are good. I was looking for any pointers whether there are any bugs which is related to memory leaks in SQL Server 2012. I know all of them are addressed with SQL Server 2012 SP2.
Application team has NO idea about SQL Server do they ? And to say SQL Server has memory leak you have to actually prove it did they showed any proof. Its common for application team to say SQL Server is leaking memory because they are unaware about fact
by default SQL Server would take as much memory as possible and would release when SQLOS asks it to do so. This might give sign that it is leaking memory BUT IT IS NOT.
As you already said AOAG is working fine so I am presuming there is nothing much to worry. To monitor memory usage in SQL Server 2012 you can use below counters
SQL Server: Memory Manager-- Target Server Memory (KB)
SQL Server: Memory Manager--Total Server Memory (KB)
SQL Server: Memory Manager- Free Memory (KB)
SQL Server: Memory Manager--Database Cache Memory (KB)

The Security ID is not valid causes memory leak in Ldap
Hi, all:
We are using the Novell LDAP Provider to allow our server application
be configured in LDAP mode. One of our clients is experiencing a memory
leak and we believe that the problem could be related to a "The Security
ID is not valid" error. When he changes to native Active Directory mode
the memory leak dissapears (he still gets the "Security ID" error, but
all works fine). So, we think that the problem caused by the "Security
ID" error is affecting the Novell Ldap Provider library. He is using a
Windows 2008 R2 platform.
My question is: Do you know if these kind of errors are properly
handled so that resources are released?
We are using the 2.1.10.1 version of the library.
Many thanks for you help,
Luis

One of tmy applications has memory leak sometimes, not always. I find most tools to check the memory leak needs to reproduce the leak, but now I can not reproduce this issue, is there any tool to analyze the source code to find the memory leak?
Don't know about source code analyzer, but dbx, the Sun Studio debugger, is capable of detecting memory leaks at run time. You can use bcheck script on your application or start dbx, issue "check -leaks" and then run your app under dbx.
