RangeError: Maximum call stack size exceeded

Dear all,
we are executing and EDGE project in a Samsung SmartTV. In more powerful models (more memory and cpu) the execution is correct. but in some old TV models we receive the following message:
File: file://c/........../EDGE_006/edge_includes/edge.2.0.1.min.js
Line No: 135
Error Detail: RangeError: Maximum call stack size exceeded.
It seems that this happens depending on the complexity of the EDGE project, as for some simple projects it works.
we would like to adjust our EDGE project for this less powerful models modifiying animations and simplifying complexity, but we dont know where to start (which animations to remove, etc.)
Or if there are some parameters in the edge API to adjust in order to increase performance in low memory browsers.
Thank you in advance,
Luis

Unless you know this DLL is using exceedingly lots of stack (at least
several dozens of MB) for whatever obscure reasons it is very unlikely
that running out of stack space is causing your problem. More likely
either the DLL does something nasty to a data pointer passed in to it or
you made an error in setting up the call to the DLL.
For instace if the DLL expects strings or array pointers to be passed in
they need to
be allocated by the caller (here LabVIEW) and you need to
tell LabVIEW to do that in the diagram code.

Call Stack Size

Is there a way to increase the call stack size of LabVIEW or to know
when it has been exceeded?
Thanks.

Maximum file size exceeded?

Recently I've bought curve 9300 - so far it looks to be the best phoned I had so far.
But yesterday I finally decided to install desktop software and check some other functions of the phone. And that's when I found a problem. I haven't installed ny media card, but there's some free space showing on the built memory. I've wanted to upload a couple of multimedia files ( .mp3 - using "file" button, I'm not using Itunes, Windows media etc) . I got an info that maximum allowed file size has been exceeded (I'm not sure it's excat phrase as I had to translate it from Polish). What's wrong? I'm pretty darn sure that file I wanted to upload is smaller than free space (mp3 of around 5MB).

Hi and Welcome to the Community!
Here is a KB that discusses that error:
KB26221 "File exceeds the maximum file size of the destination or is too large for the system" appears when saving attachment files on the BlackBerry smartphone
Hopefully it contains something useful! While it is written for the 9700, I suspect it applies to your BB as well.
Good luck and let us know!

Actually, the size constraint is on the size of the compiled P-Code, which means you should probably watch for different things. Things that don't compile down to P-Code tokens (e.g. string constants, embedded SQL) should be reviewed carefully. If you have a lot of embedded SQL (a common trap for those new to PB), you might want to consider encapsulating that in a DataWindow, which will be more network-traffic-efficient at run time anyway.
Good luck.

Desired stack size of 8197 Kb exceeds current process limit of 8192 Kb.

I've installed HP's JDK on my hp box:
HP-UX HPUX B.11.23 U ia64
However, I noticed that when I got some error just type "javac":
# java -version
java version "1.5.0.06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0.06-_12_jan_2007_03_27)
Java HotSpot(TM) Server VM (build 1.5.0.06 jinteg:01.12.07-08:49 IA64, mixed mode)
# javac
Java HotSpot(TM) Server VM warning: Desired stack size of 8197 Kb exceeds current process limit of 8192 Kb.
Well, I could compile and execute java programs on this box, but I'm curious to know the cause for the error message.
Thanks,
Tuan

What is your ulimit set to ?
e.g.
$ ulimit -a
stack(kbytes) 8192
Check your kernel limit with :
e.g.
# kctune | grep maxssiz
maxssize 8388608
maxssize_64 268435456
So you could boost it by changing the maxssize kernel parameter.
Hope this helps,

552 Message size exceeds maximum message size

Hello, I have the same problem, 10 emails I sent out bounced with the following same error message:
">>>xxxxxxxxxatxxxxxxxx.co.il(reading confirmation): 552 Message size exceeds maximum message size"
And they also sent the headers....which is all Greek to me. Being a very beginner computer user, I can't execute the good advice given here.
This is very strange since the emails so bounced only had 5 small pictures I had taken in my small, cheap dig camera, while other messages I had sent out
successfully before were probably 4 times as big.
Also, whose fault is it: my server RCN? Microsoft? I wonder...
I hope there's something easier for me to do to fix this problem?
Thanks ever so much for any help! :) Adela

It says to me that the message you sent was rejected along the way because it was too big. Ask the e-mail administrator of the system that's bouncing it.

ORA-29279:SMTP permanent error:552 5.3.4 Message size exceeds fixed maximum

Hi,
I can send attachments smaller than 25MB.
But my attachment is 27MB and it fails. Don't ask why I need to send this big file by email, I have to.
Where can I change this maximum size?
- any parameter in utl_smpt?
- any parameter in server where DB is located? (Linux 2.6.18-238.1.1.el5)
- any parameter in smtp machine server?
Thanks.

Edited by: Joaquin Gonzalez on Apr 12, 2012 11:46 AM

The actual error, "+552 5.3.4 Message size exceeds fixed maximum+", is from the smtp server. Oracle expects a 0 return code and instead get a 522 return code in the smtp server's response (to the DATA command). So Oracle throws an exception that in turn contains the error response of the smtp server.
Interesting that you did not get the error earlier - many smtp servers have the ceiling set a lot lower and you can expect this error after sending around 5MB of data.
There are ways around this. Send the attachment as multiple fragments using a compression technology like zip or rar (where it is fairly easy for the recipient to reconstruct the source from the pieces send).
There's also another problem. The 20+ MB e-mail may be accepted by the smtp server, but the POP3, IMAP (or Exchange?) account (mail drop) may not accept an e-mail of that size.
Success is also assuming that you are delivering that mail directly to the correct/target smtp server. If not, then that e-mail needs to be relayed via a number of intermediate smtp servers before reaching the target smtp server and domain.
And there is a good chance that one of these relay servers will object to the size of the e-mail and trigger a hard bounce response.
Keeping an attachment size down to at most 3 to 5 MB is IMO the better approach as that guarantees a better chance of delivery than a 20+ MB e-mail.

Stack size for native thread attaching to JVM

All:
I have a native thread (see below, FailoverCallbackThread) that attaches to the JVM and does a Java call through JNI. The stack size for the native thread is 256KB.

This causes stack overflow in Oracle JRockit JVM. (It does not cause overflow with Oracle Sun JDK.) Is there a recommended stack size for this use case for JRockit? Is there a way to compute it roughly?

How do I found default heap size, stack size for the
thread, number of threads per jvm/process supported ?The threads is OS, OS install and jvm version specific. That information is also not useful. If you create the maximum number of threads that your application can create you will run out of memory. Threads require memory. And it is unlikely to run very well either.
The default heap size and stack size are documented in the javadocs that explain the tools that come with the sun jdk.
and how the above things will vary for each OS and how
do I found ? Threads vary by OS, and OS install. The others do not (at least not with the sun jvm.)
If I get "OutOfMemoryError: Unable to create new native thread" Most of the time it indicates a design problem in your code. At the very lease, you should consider using a thread pool instead.
I found in one forum, in linux you can create maximum
of 894 threads. Is it true ?Seems high since in linux each thread is a new process, but it could be.

Checking stack size

I have written a JNI app and it seems to work fine, but processing with very large files I run out of stack space.
I have solved this issue for the moment by changing the stack size with the -Xss param to java but this is not the ideal issue because with even bigger files I still will have issues.
So, I have 3 questions:
1. Is there any way (in the c++ dll) to query the total stack size ?
2. Is there any way to determine free (available) stack size ?
3. Is there any way to increase the stack size when the dll is already running (if it starts to get low)
I look forward to your thoughts
Ding

I have written a JNI app and it seems to workfine,
but processing with very large files I run out
of
stack space.
That suggests that you have a design problem.
As a guess you are using recursion. Start by
unrolling the recursion code to produce a
non-recursive solution.ood Guess but there is no recursion in my code :-)
While I am always trying to optimize my design, in
this case I am constrained by 3rd party c libraries
that are using very large multi dimensional arrays of
doubles that are neccessary for lots of complicated
math doing triangualtion of satellite data. So, I
have no control over how much memory they want to
consume.
ood Guess but there is no recursion in my code :-)
Then it is unclear as to what you think a good solution would entail.
Do you intend to just to keep retrying the processing step with ever increasing stack sizes? Will that not impact the processing time? Why not just start with a larger stack size? And if the stack size just continues to grow because the file sizes are continuing to grow then what?

One solution would be to create a C app, not a java one. Find the maximum amount of stack space that you can allocate via a C app and still operate (this depends on what happens with the file itself.) The output goes to a file.
Your java app just starts that in a separate process space.

I was referring to the native C stack, used within
the c++ dll, for which the java VM starts via the
-Vss flag. I know the initial total as I am setting
it at runtime. I just wanted to print the value from
within the dll. #2 (below) is more important
though.
That would depend on your OS and compiler.
2. Is there any way to determine free(available)
stack size ? This is the part I was mostly hoping for an answer
to, as I need to communicate with the parent java app
if the stack space gets too low, instead of just
allowing the dll to crash when it runs out
That is a two part question. You want to know the size and you want to know if it gets 'too low'.
You suggested that this is all stack based processsing. So unless you have C methods that are called by the library and in addition it is recursive in nature then this is not possible. There is no point where you could detect it.
You can analyze the file yourself and compute a size before you start processing. But if that is what you are doing then you should do it first and let the java app know the result.
Other than that most OSes allow you to catch 'system exceptions' (which might or might not be actual C++ exceptions.) One of these would be generated when the stack overflows.
You then convert into something that java understands.
For example in Windows there is a function that allows you to set up system exceptions so that they cause a C++ exception to be thrown. You would then catch this exception and convert it into a java exception.
That lets you know that it didn't work but then what?
For example in windows you can create a custom stack for the dll but only when the dll loads (so far as I know.) So to restart this you would have to unload the dll and that means that you will have to have everything wrapped in a custom class loader (which is the only way to cause a dll to be unloaded.)
Not to mention that in my experience the windows function that I mentioned above doesn't necessarily always catch everything.
>>>
>>
No. The VM must be restarted.if that is true, It i a bummer :(You can however, on most OSes, increase the stack size for the shared library. This is done on start up of the shared library. To resize it however means that the shared library must be reloaded. And the only way you can do that in the Sun VM is with a class loader.

Max-stack-size - default_stksize

Hi,
First, sorry for my english ^^
I'm new on Solaris. I installed Solaris 10 on Sun V490 . I use Core Network.
Why with the default setting, daemons or process of the OS "don't work" like this:
Jun 17 14:50:10 unknown genunix: [ID 883052 kern.notice] basic rctl process.max-stack-size (value 8683520) exceeded by process 353In this example I generate the error with the format command. But I get this error with other command or deamon like nscd.
I had the same problem with the value max-file-descriptor. The values set by projmod for the system project did not seem take effect. Thus I used the "old" parameters rlim_fd_cur, rlim_fd_max. Now it's ok.
I find this parameter default_stksize in the Sun documentation. I put this in my /etc/system file:
set default_stksize=16384At the boot time I have no error message for the value, but the max-stack-size value is the same:
prctl -n process.max-stack-size 130
process: 130: /usr/sbin/nscd
NAME PRIVILEGE VALUE FLAG ACTION RECIPIENT
process.max-stack-size
basic 8,28MB - deny 130
privileged 127MB - deny -
system 2,00GB max deny -
nscd is in the system project:
ps -p 130 -o project
PROJECT
system
Thank in advance, any idea is welcome.

Hi Prasad,
Block Size is the number of parallel processes that are being executed in background during the application. This is normally a configuration activity to be configured in line with basis.
In Block size, we enter the number of objects to be processed per block by the CIF comparison/reconciliation during data selection in SAP APO or in the partner system.
If you increase the block size, the memory required also increases. This has a positive effect on performance. If processes are cancelled due to lack of memory, you can decrease the block size to save memory.
If you do not enter anything here, the system determines the block size dynamically from the number of objects that actually exist and the maximum number of work processes available.
Normally, when you execute a job in background, it picks up the application server automatically or by manually defined server. In parallel processing, at a time, one or more job of the same identify can be triggered under this scenario by defining application servers. But too many parallel processing activity will affect the performance.
One needs to define the parallel processes also to control system behaviour. The Parallel processing profile is defined for parallel processing of background jobs. You then assign these profiles to variants in the applications.

Cannot increase the stack size

Hi,
We have a program which gives a StackOverflowError. Trying the increase the stack size using command line options does not work. A simple program shows that the stack is the same size, whatever option we set.
This is the program:
class StackOverflowTest
public static int counter = 0;
public static void main(String[] a)
try {
sub();
} catch (StackOverflowError e)
System.out.println("recursive calls: "+counter);
public static void sub()
counter++;
sub();
We tried several -Xss (and -Xoss) settings: 600K, 2048K, 4M but got the same recursion deep: 16683 (with Eclipse), or 16689 (command line).
We used Windows XP.
Do you have any clue?
Many thanks,
Zsolt

Table size exceeds Keep Pool Size (db_keep_cache_size)

Hello,
We have a situation where one of our applications started performing bad since last week.
After some analysis, it was found this was due to data increase in a table that was stored in KEEP POOL.
After the data increase, the table size exceeded db_keep_cache_size.
I was of the opinion that in such cases KEEP POOL will still be used but the remaining data will be brought in as needed from the table.
But, I ran some tests and found it is not the case. If the table size exceeds db_keep_cache_size, then KEEP POOL is not used at all.
Is my inference correct here ?

Does it mean that if the db_keep_cache_size < table size, there is no caching for that table ?
Or am I missing something ?

Hello Jonathan,
Many thanks for your response.
Here is the test I ran;
SQL> select buffer_pool,blocks from dba_tables where owner = 'HR' and table_name = 'T1';
BUFFER_     BLOCKS
KEEP          1977
SQL> select count(*) from v$bh where objd = (select data_object_id from dba_objects where owner = 'HR' and object_name = 'T1');
COUNT(*)
      1939
SQL> show parameter db_keep_cache_size
NAME                                 TYPE        VALUE
db_keep_cache_size                   big integer 20M
SQL>
SQL> alter system set db_keep_cache_size = 5M scope=both;
System altered.
SQL> select count(*) from hr.t1;
COUNT(*)
    135496
SQL> select count(*) from v$bh where objd = (select data_object_id from dba_objects where owner = 'HR' and object_name = 'T1');
COUNT(*)
       992I think my inference is wrong and as you said I am indeed seeing the effect of tail end flushing the start of the table.

Change the default stack size in the java.exe file

Does anyone know how to change the default stack size of the jvm?
I'm having problems with my stack. Is there anyway I can change it. I found a tool editbin.exe which is shipped with Visual c++, however I don't have the tool.
Thanks,
William

I am using JNI to connect java with a C++ application.
When calling the C++ appliction, STACK_OVERFLOW
happends. I tried java -Xss<size> to increase the
stack size, but failed.This has nothing to do with the above question.
Does anyone knows why?Probably because the java parameter specifies the java stack size and not the C++ stack size.

Maximum Data file size in 10g,11g

DB Versions:10g, 11g
OS & versions: Aix 6.1, Sun OS 5.9, Solaris 10
This is what Oracle 11g Documentation
http://download.oracle.com/docs/cd/B28359_01/server.111/b28320/limits002.htm
says about the Maximum Data file size
Operating system dependent. Limited by maximum operating system file size;typically 2^22 or 4 MB blocksI don't understand what this 2^22 thing is.
In our AIX machine and ulimit command show
$ ulimit -a
time(seconds)        unlimited
file(blocks)         unlimited <-------------------------------------------
data(kbytes)         unlimited
stack(kbytes)        4194304
memory(kbytes)       unlimited
coredump(blocks)     unlimited
nofiles(descriptors) unlimited
threads(per process) unlimited
processes(per user) unlimitedSo, this means, In AIX that both the OS and Oracle can create a data file of any Size. Right?
What about 10g, 11g DBs running on Sun OS 5.9 and Solaris 10 ? Is there any Limit on the data file size?

How do i determine maximum number of blocks for an OS?df -g would give you the block size. OS blocksize is 512 bytes on AIX.
Lets say the db_block_size is 8k. What would the maximum file size for data file in Small File tablespace and Big File tablespace be?Smallfile (traditional) Tablespaces - A smallfile tablespace is a traditional Oracle tablespace, which can contain 1022 datafiles or tempfiles, each of which can contain up to approximately 4 million (222) blocks. - 32G
A bigfile tablespace contains only one datafile or tempfile, which can contain up to approximately 4 billion ( 232 ) blocks. The maximum size of the single datafile or tempfile is 128 terabytes (TB) for a tablespace with 32K blocks and 32TB for a tablespace with 8K blocks.
