Refreshing DataControl causes OutOfMemory Stack Overflow
The basic question is “How can I programtically refresh a DC so that it ‘re-reads’ in the values from an underlying managed bean in session that was returned by a web service proxy”?
In trying to solve this first question we saw hints on the forums to get a handle to the binding and call executeQuery() to force a refresh. We tried this during the invokeApplication phase just after we called our WS Proxy service that returned a POJO (e.g. DataRequest) which we placed into session. We have a DataRequestWrapper object that exposes a getDataRequest() method. We expose the DataRequestWrapper as a DataControl so as to bind the object hierachy of the DataRequest to our UI Views. The DataRequestWrapper.getDataRequest() method returns the reference to the DataReuquest stored in session (i.e. Java RefID=1).
So as we start our sequence we create an new DataRequest, put it into session and as users enter data, the data control pushes the values into the session bean RefID=1. Works as expected, then the user hits save and we have a method-action that calls the wrapper method who gets the session bean and calls the WS.save(). That service returns a decorated DataRequest object (i.e. RefID=2). We place that into session, but on rendering of the view the DC are still firing agains RefID=1.
We set all the CacheResult = false on the bindings in the pages. We see the DC refreshing, but (as expected) its occuring prior to the InvokeApplication phase which is before we've called our service to get RefID=2.
So in our wrapper, after updating the session reference with RefID=2, we access the binding and call executeQuery(). We see the getters start firing against the DataReuqest RefID=2 which we assume is the DC refreshing itself. The thread continues on as the view rendering presumably is occuring, but it never completes......stack dump in JRockit...a portion of the stack below.... There seems to possibly be a recursive loop problem here, not sure if its because of something we did (we can't find any where that we might be calling ourself...hiearchy has a strict parent-child relationships...no cross tree references). The refresh of the tree obviosuly works in other phases....so not sure where to go with this.
Should the executeQuery() be expected to work and the overflow be a potential defect? Should we not be calling executeQuery()? Should we be calling the exectureQuery() somewhere else (we also tried in a beforePhase listener prior to renderResponse with the same stack dump)? Should we being using the BindingContainer.refresh() (which seems to have no affect)? Are we looking at this the wrong way?

Thanks Frank, let me take step bkacwards in our implementation choice of the DC and managed bean....that might be where we took a wrong step? So we saw 2 POJOs being instantiated as you described, and we began to try and figure out how to get a handle to the POJO instantiated by the DC so that we could pass it to our page-flow method actions since it had the captured user data. The service implementations are in a different set of facade classes...so we've been thinking/treating the DC more as a model and maybe the service interfaces should actually be invoked on the DC POJO and then reference 'this' in the service method invocations parameters?
So is the implied scope of the POJO DC at the session level? Is there a way to reference the instance handled by the DC through EL?
As a follow up on the stack trace I reference, I think we found the conflict. We have a parent page bound to the DC and that view has a region to other pages which support different page flows for entering data on the child hierarchy under the root object. Both pages bind to the same DC object hierarcy and so iterators by the same name were created on each page def. What we found was that the 2 iterators that manage the root object were not set consistently. So in the parent page the 'requestIterator' and the child page's 'requestIterator' were both set to CacheResult=false but we had missed the combination of setting both Refresh settings to renderModel. So the read-only fields are now being refreshed.
However a further investigation showed that the writable fields were not because the source view and targer view for the page flow are the same view in this case and the lifecycle is different here. So we added the executeQuery invocation back in after our service and the OOM is gone. The OOM happened when the region page Refresh was set to deferred. Goes away when both set to renderModel.

Error while executing web part: System.StackOverflowException: Operation caused a stack overflow
Hello All,
I have a list with about 70 or so columns. When I try to access a NewForm for this list, I get an 'Unable to display this web part' error.
Looking at the Correlation always says it is a:
"Error while executing web part: System.StackOverflowException: Operation caused a stack overflow."
I have read many pages on the internet that it is due to an XsltTransformTimeOut value set to 1. I have applied the Feb 2012 CU and tried changing the value to 5, 10, 150, 250 and each time I reset IIS before I tried loading the form again. Each one has
failed and the correlation says the same thing (stack overflow).
I do not know what to do next because every page on the net says it is from that timeout value but I have followed the steps properly to change it but nothing has worked.
Thank you for your help!You may be exceeding the number of columns threshold with 70 or so columns in your list.
Take a look at the Column limits here:
http://technet.microsoft.com/en-us/library/cc262787.aspx#Column
Okay, so please help me to understand this. It says the maximum value for single line of text is 276 and the size per column is 28 bytes. How would I know if I have pushed the limit? I just multiplied 28 x the number of single line of text columns in that
list and the answer is 840. I do have many other columns, such as multiple lines of text and choice. I do not know if the theory above is correct though, because 28 does not go evenly into 276 (276/28 = 9.857)
Please help me understand how to calculate my fields to see if I have went beyond the limits.
Thank you! -

How do I fix a stack overflow?
Hi,
Well I hope I am posting this in the right section of topics.
I am new to programing.At the moment I am sudying loops in Java.
I did something that has caused
a "stack overflow" in my computer(Whatever that is).
Is this really bad for my computer, and how do I fix it?
thanks.Just to add a little more..
The Stack is a special area of memory in the virtual machine. It stores variables that fall in and out of scope. When methods are called, the values of variables are often placed on the stack. The problem with a stack overflow arises when a method calls itself, either directly or indirectly, and never stops doing so. This could be called 'uncontrolled recursion'.
When this happens, the stack will fill up until the method can no longer be called, and at this point a StackOverflowError will be thrown.
It is important to note that this will not do bad things to your machine, because the stack is quite small (circa 256KB ?). If you don't catch the Error with a catch(Throwable) statement, the VM will exit automatically - all you have to do is fix the bug. -

All of a sudden, I am getting messages on the home screen for "Stack Overflow at line 133 etc"
What does this mean and do I need to worry about it? Plus, how do I stop it?
And it does not give a full error.....just a small box that says, "Stack Overflow at line 133" or sometimes a different number.
I am using Windows 7 Home Premium, Mozilla Firefox Browser(do not like IE).
I also have:
Avast Anti-virus,
ZoneAlarm Firewall,
Advanced System Care Pro,
SpywareBlaster,
Malware Fighter(part of the ASC stable)
and Ccleaner.........I hasten to add, not all scans running at the same time.
Is it okay to have all of these?
Maybe some are conflicting with each other and causing the "Stack Overflow" problem?
Thankyou for any help you can give.Does it also tell in which file that error occurs?

Recursive function definition results in stack overflow
I am writing a library script to handle some basic calculations with complex numbers which includes a function, powerN(), that raises (or is supposed to raise) a complex number to the Nth power. The function compiles but gives a stack overflow error when called. The language guide has an example (p. 286 in PDF version- recursive subroutines section) of a recursive definition of a function which gives the factorial of a number, and my powerN function seems to be analogous. Can anyone shed some light on whatever the problem is? Relevant code examples are below. Thanks for any insights.
-----Apple recursive subroutine for factorials------
on factorial(x)
if x > 0 then
return x * (factorial(x - 1))
else
return 1
end if
end factorial
-----End Apple recursive subroutine for factorials------
-----My script with problematic powerN() function------
--Complex numbers a+b(i), x+y(i) represented by {a,b}, {x,y}
on multiply({a, b}, {x, y})
return {(a * x + b * y), (b * x + a * y)}
end multiply
--above multiply function works
on powerN({a, b}, N)
return multiply({a, b}, powerN({a, b}, N - 1))
end powerN
--above powerN function gives stack overflow error
-----End my script with problematic powerN() function------the problem is that your recursion has no end case, thus causing a stack overflow
you should add a test as follows :
on powerN({a, b}, N)
if N>0 then
return multiply({a, b}, powerN({a, b}, N - 1))
else
return 1
end if
end powerN
by the way, shouldn't your complex multiplication look like :
on multiply({a, b}, {x, y})
return {(a * x - b * y), (b * x + a * y)}
end multiply -
C++ stack overflow on desctruction of Set::View
Hi,
I've encountered a problem when querying large sets of data from coherence.
Gven the following code;
// load cache with a large data set
char buff[128] = {0};
for( int i = 0; i < 100000; ++i )
sprintf_s(buff,128,"key%05d",i);
// random binary data
int len = 128 + rand() % 512;
Array<octet_t>::Handle hab = Array<octet_t>::create(len);
hCache->put(String::create(buff),hab);
// query the cache, and print the results
struct tmpIt
Filter::View vAll;
Set::View vSetResult;
tmpIt *t = new tmpIt;
t->vAll = AlwaysFilter::create();
t->vSetResult = hCache->entrySet(t->vAll);
// iterate over the results
int ncount = 0;
for (Iterator::Handle hIter = t->vSetResult->iterator(); hIter->hasNext(); )
Map::Entry::View vEntry = cast<Map::Entry::View>(hIter->next());
String::View vKey = cast<String::View>(vEntry->getKey());
Object::View vValue = vEntry->getValue();
Array<octet_t>::Handle dt = cast<Array<octet_t>::Handle>(vEntry->getValue());
ncount++;
if( (ncount % 2000) == 0 )
std::cout << ncount << std::endl;
// delete the struct, thus forcing the destruction of vSetResult
delete t;On deleting the struct 't' causes a stack overflow deep within coherence. I'm guessing there's some kind of recursive delete that works on smaller data sets.
Can you please advise me on what to do in this situation, as this has put a halt to my coherence integrartion :)
Cheers
Rich
Edited by: user9929344 on 22-Oct-2008 01:57Hi Rich,
I've tried your test out in a few environments using both debug and release builds and have not been able to reproduce the issue. My guess is that it may have something to do with your build settings. Can you try building it using the build.cmd script which we ship with the product. This can be done by creating a new subdirectory under examples for your test, for instance "overflow", place you source code in that directory and then from the examples directory run "build overflow". You can then run the test by executing "run overflow". This is how I've tested an all seems to be ok. Assuming this resolves the issues on your side, you can have a look at the compiler/linker settings used in the build.cmd script and try applying them to your build process. If this does not resolve the issue, it would be useful if you could send us a fully buildable example (and build script) which reproduces it. Also if you could include the OS and compiler versions that would help.
In testing your source code I ran into a few small things I thought I should point out to you.
- while loading if you batch your puts into a local HashMap and then do periodic hCache->putAll() operations loading will be faster:
// load cache with a large data set
char buff[128] = {0};
Map::Handle hMapBatch = HashMap::create();
for( int i = 0, c = atoi(argv[2]); i < c; ++i )
sprintf(buff,"key%05d",i);
// random binary data
int len = 128 + rand() % 512;
Array<octet_t>::Handle hab = Array<octet_t>::create(len);
hMapBatch->put(String::create(buff),hab);
if ((i % 2000) == 0)
hCache->putAll(hMapBatch);
hMapBatch->clear();
std::cout << "loaded " << i << std::endl;
hCache->putAll(hMapBatch);
hMapBatch->clear(); - During iteration you should not cast the values back to Handles, but rather only to Views. It is not guaranteed that the cache will return non-const references to the data.
I did validate that the test did not fail prior to making the above modifications.
thanks,

at org/apache/xalan/templatesHi,
I had a JRockit Stack overflow core too, but on a Red Hat Linux 3.2.3, and without writing any recursive code !
===== BEGIN DUMP =============================================================
JRockit dump produced after 3 days, 08:38:33 on Wed Dec 21 13:24:43 2005
Additional information is available in:
/exec/applis/30abo1/G01R00C01/dt/sh/jrockit.10040.dump
No core file will be created because core dumps have been
disabled. To enable core dumping, try "ulimit -c unlimited"
before starting JRockit again.
Please send the file(s), information about your system
setup and the program you were running to [email protected]. Thank you.

Stack overflow error while creating connection using Oracle10G dirver
Hi,
Our web application built on Servlets runs on the iPlanet web server (In solaris machine). Earlier we used JDK 1.5 update 6 with oracle 9i driver and now got migrated to JDK 1.5 update 10 with same driver. Everything went fine until we started testing the environment with oracle 10G driver. Java 1.5 update 10 with oracle 10G driver throws "Stack overflow error".
Driver version is - 10.2.0.2.0
This occurs only when I access the portal. When I created the single main program and try to run it in the solaris machine it works fine. But wen I try to access the portal keeping this driver under classpath, it fails. Please let me know if anyone have any clues.
When I looked into it, I am able to find that the "stack overflow error" occurs at the point the code line DriverManager.Getconnection("url", "username", "pwd") executes.
Thanks in advance
below the stacktrace of the exception from webserver error log..

Nandakumar_sYes, request goes through connection pool but weird
thing is application throws stack excatly where
DriverManager.getConnection gets executed.
Not weird at all.
This is what I am guessing that you did. You changed the driver and some other stuff, like configuration information.
Then when it blew up you tracked down in your code where you see the stack overflow. That happens to be on the connection line. That is not where the overflow 'occurs' - it merely represents where you saw it.
That line however isn't using the oracle driver. What it is using is a connection pool of some sort. That connection pool is configured somewhere. And that configuration is self-referential (or maybe refers to a another driver which refers back to the original.)
And that causes you stack over flow. -

1) You are running on RHEL3u4, which is formally an "unsupported configuration". You should upgrade the OS to u5 or later. There are known I/O issues in RHEL3u4 and earlier. I don't think it has anything to do with your crash, but better safe than sorry. See http://e-docs.bea.com/jrockit/jrdocs/suppPlat/supp_142.html
2) You may want to try the latest JRockit update, which you can find here: http://commerce.bea.com/products/weblogicjrockit/1.4.2/142_x.jsp
3) If neither of the above helps, or you can't make an upgrade in your production environment, open a ticket with BEA Support. Before you do that, try to reproduce the crash after setting "ulimit -c unlimited" in the shell so that you get a proper core file. -
Stack overflow when calling a DLL
I have developped a DLL in Ada.
I tried to call a function of this DLL from a C++ executable.
My program crashed because of a stack overflow.
Then, I increased the stack size of my program (linker option), and now it
works.
Calling this DLL through the call library function from a 6.0 Labview
program causes the same stack overflow.
How could I increase the stack size of my Labview program ?
Thanks.Hi,
I have never come across this issue but here are a few things you can try:
1) Change the Calling Convention between C and StdCall(WINAPI). The main difference between the two calling conventions has to do with when the stack is cleaned up. In one method, the stack is cleaned earlier than in the other method.
2) Call your dll with LabVIEW 7.0. You can find the evaluation version of the latest version at http://www.ni.com/labview
Good luck

Getting stack overflow exception whilst reading from HashMap
hi,
We are getting stack oveflow exception exception whilst reading from the HashMap.
Following are few details about the code
We have a swing based client and Session beans and Entity beans deployed on Weblogic Server.
When the server is started, a session bean method queries to data base and creates a java object for each row in the data base.This java object is then stored in HashMap. These java objects have all get/set methods . and it has attributes of primitive data type as well as other java objects.This Hahsmap is then returned to client.
When client calls this method and the method processes succesfuly , but when tries to return the HashMap, it gives Stack overflow exception.
Looking at the stack trace i think this exception is thrown when the HashMap.readObject() methods is being invoked.
does any body have any idea about this ? a quick help is much appriciated.Stack overflow is often caused by infinity loops No, an infinite loop would be like while (true) {
// stuff
} That doesn't cause stack overflow.
or
recursive method calls.Bingo. -
Stack overflow exception when selecting the Organization tab on a contact card
I have encountered a reproducible crash in the Lync 2013 client. The crash happens after selecting the "Organization" tab when viewing a contact card.
The crash appears to happen because of a stack overflow with MSO.DLL. I have applied the latest hotfix for that module but the crash persists.
Before I open a case with MSFT, can anyone offer any insight? Perhaps this is being seen elsewhere?

FileDescription: Microsoft Office 2013 componentI actually think I may have figured this out. I took a network trace during the crash. What I found is that Lync is performing repeated LDAP searches over and over until it crashes from the stack overflow. Digging into
the searches, I found the same two user CN's being alternated one after another.
It appears that this crash may be the result of a "Circular Reference" where the two users are each listed as the others manager in their user object.
Example:
User1: Manager = User2
User2: Manager = User1
Proving this as the cause will take me some additional time as these two users are at the top of the Org Chart. :)
I'll update this post with the results when I get them. -
Regex gurus: Intermittent stack overflow from Matcher?
I've been using the following code to grep out links from <a> tags in html. For some pages it is throwing stack overflows from within the pattern matcher class. I am wondering, is there a better way to be doing this, or did I make some kind of mistake that is causing this to happen? Any help or advice would be greatly appreciated.
private static final String matchATags = "(?i)<a(.|\\n)*?>";
private static final String matchHREFPre = "(?i)\\A(.|\n)*HREF\\s*=\\s*\"";
private static final String matchHREFPost = "\"(.|\n)*$";
private static final Pattern tagPattern = Pattern.compile(matchATags);
protected List<String>
getLinkText(
String text
if (text == null)
throw new NullPointerException("null text");
Matcher matcher = tagPattern.matcher(text);
ArrayList<String> linkList = new ArrayList<String>();
while (matcher.find()){
String link = text.substring(matcher.start(), matcher.end());
link = link.replaceAll(matchHREFPre, "");
link = link.replaceAll(matchHREFPost, "");
linkList.add(link);
return linkList;

...Never do this in a regex: "(.|\n)" // WRONG If you want to match any character including line separators, use the dot in DOTALL mode: "(?s)." If there are characters you don't want to match, you can use a negated character class. In this case, you probably don't want to match angle brackets, so you could use this: "[^<>]" The way you're doing it (alternation) is extremely inefficient. Also, you aren't allowing for other kinds of line separator, like "\r\n" (DOS) and "\r" (older Mac OS). But if you do it the right way, you don't need to worry about that.

Stack overflow resolution and question
on Oct 8th, I posted the stack overflow at the end of this message. I
figured out the problem, but would like some insight into why it manifested
itself as a stack overflow. Why isn't it a heap overflow? I care which
overflows because a problem could still exist.
PROBLEM
Our server transmits an event object to our client. The event object has
references to 2 member objects which describe the context of the event.
About 200 of each type of member object is created. They are kept in a
HashMap so we can reuse them.
However, in one case, a new member object is created every time an event is
transmitted. That's the bug - about a thousand events a second are created
so one thousand of each member object is created, then transmitted. When we
changed the member object creation to a member HashMap lookup, the stack
trace stopped.
PROFILING
To isolate the problem, we profiled the client with OptimizeIt. This
showed about 150,000 member objects and about 148,000
java.io.ObjectInputStream$HandleTable$HandleList instances. In some runs,
Garbage collection reduced the number to about 60,000. In other runs,
Garbage Collection did not run before the stack error occurred.
If we create lots of member objects in the heap, then the heap should
overflow. Why does the stack overflow?

Well, the HandleList entries mark a dependency from a parent object to a
child (i.e referer and referee), and my guess is that you at some point
simply manage to serialize a very long object chain:
Obj1 -[ ref to]-> Obj2 -[ref to]-> Obj3 and so on.
This will cause a recursive deserialization (actually, it causes a
recursive serialization also, so sender should SOE as well). The amount
of memeory used is probably high, but not OOM high. Note, that for this
to happen, all objects sent must be unique, which you state that they
are. Question is how you've managed to create an object chain like this.
Another explanation might be that there is actually a bug somewhere in
the sender that causes a circular reference between two (or more)
objects to be sent not as reference handles, but unique objects. I
cannot see what would cause this though. I assume that you don't have
concurrency issues (i.e only one thread uses the ObjectOutput/Input
streams at one time)?
Do you have an exact count of the transmitted object? It might help me
figure out exactly what happend.
