Buffer overflow problem
In transaction qa32, I put my data and I enter usage decision. In inspection lot stock, when I enter one variable and push the button save.I get the error
Buffer is too small,
When I debug the system
CALL 'ThNoGet' ID 'BNRIV' FIELD BNRIV
ID 'NO' FIELD G_NOIVBUFFER
ID 'QUAN' FIELD P_QUANTITY
ID 'PERCENT' FIELD TNRO-PERCENTAGE
ID 'NONRSWAP' FIELD TNRO-NONRSWAP.
here sy-subrc returns 11 for one number range object. how can i solve the problem? how can i enlarge the buffer for this number range object?
Hi,
In SNRO check the number range objects associated with it, buffer for number range which is used is the probelm.
you can increase the buffer.
Thanks

I have created executable file, tested it for several days on my laptop and send it to the customer together with hardware.
As soon as he received it he faced buffer overflow problem.
Is it possible to eliminate this poblem?
When this error appeares the part of the program that does acceleration analysis still workes but signal generation stopped.
Unfortunately I do not have this hardware so I have to modify the program wihou testing it.
What are the ways to avoid buffer overflow(one of them is probably just to use DAQmx configure input buffer but I do not know where to insert it and how configure it).

Generator-Accelerometer New.vi 636 KBHere is what I see is happening.
You are using DAQ assistant in the 2nd loop to acquire 1000 samples at 1000 Hz It is set for continuous samples. So that will take a second. Then the data is passed of to the other functions. I don't know how long they would take to run, but they are pretty substantial. (By the way, your write measurment file as no data going into it.) If it takes longer than a second, then the DAQ functions which have been continuing, will have the buffer overwritten and you will get the error.
You could ignore the error, but that also means you've lost data which may or may not be important.
It is better to pass the data off into a queue. Let another parallel loop do the number crunching and saving to file. Search the labview help and the discussion forums for producer/consumer design architecture for examples. With only the DAQ assistant in the loop, you will get all of the data. The only risk would be if the queue would grow without bounds in the event that each chunk of data still takes longer than a second to process.
Putting a wait statement in the top loop as well will help. Without a wait statement, a loop will run as fast as it possibly can. Since you are mainly reading a local variable and some controls such as the stop button, you probably don't need to run instantaneously. Even a small wait of a few milliseconds can help yield processor time to other loops.
In your top loop, you are recalculating the waveform and writing it to the analog output on every iteration. It would be better to put that code in a case statement that only executes in the event the values change. I believe with continuous samples, and if you allow that channel to regenerate its data, the analog output will run continuously without needing to update it every iteration.
Also, please move your front panel down and size it to fit closer to the front panel controls. For some reason your VI appears with the title bar off the top of the screen.

Hi
Ive read a lot that java eliminates Buffer overflow problems. Could some one please elaborate how this is done.
Also if i were to limit the send and receive buffer sizes for a given socket by setting them to a small size and then send a String value over the socket with a larger byte size wouldn't that cause a buffer overflow ?

Problem of buffer overflow in Iplanet 6.0sp1
Hi,
I am getting these following error messages in the logs
[30/Mar/2004:12:55:06] warning (19529): flex log buffer overflow- greater than 4096 characters
Also I am getting a error in logs like filename.ext is temporarly not available
I am not able to figure out why we are getting this error. If its a patch which needs to be put on the web server, then which patch I would be needing to install.
NikhilThis has been answered before:

Spool file error - Buffer Overflow
I've a sql script that is running from a.sql file. The script fetches almost 9 million data as a result of the query. Main problem is related to spool file generation. It is saying buffer overflow. But, when i write that query from sql prompts it is running within 2 mins and completes the task within 15 mins.
I've written -
set serveroutput on size ######
But, still it is not working. Total application is freeze whenever i want to run it. Tell me any suggestion if u have.
Satyaki.i guess what you are more concerned with is the output produced by your query (the spool file).
you need not to see what is displayed on the screen all you need is open up the spool file to
check for those data in there.
to suppress the output from the screen and still generates spool file. use the SET TERMOUT option.
e.g.
-- code for a producing a sample spool file
spool r:\sample_spool.txt;
select * from emp;
spool off;
at the SQL*Plus command line:
SQL> @r:\sample_spool.sql;

Short dump in SAP R/3: SQL statement buffer overflow?
Hello,
I hope someone can help us with the following problem:
A short dump in SAP R/3 (DBIF_RSQL_INVALID_RSQL, CX_SY_OPEN_SQL_DB)
occurred during a delta load, which worked fine for several month.
The custom code crashes at a FETCH NEXT CURSOR statement.
I assume, it might be a SQL statement buffer overflow in SAP R/3?
The problem can be reproduced by RSA3, and is therefore not time-dependent.
The problem did not occur before or on the quality assurance system.
Cursor code:
Read all entries since last transfer (delta mechanism)
OPEN CURSOR WITH HOLD s_cursor FOR
SELECT * FROM ekko
WHERE ebeln IN t_selopt_ekko.
t_selopt_ekko has up to 60.000 data sets, which worked fine in the past.
It is very likely that the amount of data during the first crash did not exceed this.
SQL-Trace of RSA3 call:
It seems that 25150 data set can be processed via fetch before the short dump occurs
After that object SNAP is written:
"...DBIF_RSQL_INVALID_RSQL...dynpen00 + 0xab0 at dymain.c:1645 dw.sapP82_D82

During dump creation the following occurs:

DBIF_INCL_INTERNAL_CALL_CODE..."
Basis says, that the Oracle data base works fine. The problem seems to be a SAP R/3 buffer.
Does anyone had a similar problem or knows where such a buffer might be or how it can be enlarged?
Best regards
Thomas
P.S.
Found a thread that contains part of the dump message "dynpen00 + 0xab0 at dymain.c:1645":
Thread: dump giving by std prg contains -> seems not to be helpful
Found a similar thread:
Thread: Short dump in RSA3 --Z Data Source -> table space or somting else?
Edited by: Thomas Köpp on Apr 1, 2009 11:39 AMHi Thomas,
Its due to different field length.
Just check it out in code after FETCH NEXT CURSOR what internal table you have mention.
that internal table shoul deffined by taking refrence of ekko, because your code is
OPEN CURSOR WITH HOLD s_cursor FOR
SELECT * FROM ekko
WHERE ebeln IN t_selopt_ekko.
hope you got solution.

Microsoft C++ Buffer Overflow Error
I have created two movies from iPhoto on my Mac. When I move them to an XP machine, sometime after 30 minutes of playing, I get the Microsoft C++ Buffer Overflow Error message, and Quicktime for Windows aborts. I have no problems playing them to completion on several Macs.
I upgraded to the latest QT version, still see the problem.
Any help appreciated.You're having the same issue as I...see my post here: http://discussions.apple.com/thread.jspa?threadID=672272&tstart=30

Exception of buffer overflow.
Hi There,
I have a code to read the text file in jsp, the problem i am facing is of buffer overflow as the text file contains more than 2000 records and when i upload data to database it throws exception of buffer overflow, any help will be appriciated.
Thanks.P.S. A JSP should, obviously, do nothing but produce HTML, which is what it is meant for after all. Any other actions should, of course, be handled be external classes and uploads and other "like" actions should be done by servlets, again, of course. You do know this, right? You do know that scriptlets in a JSP are 1) just plain wrong, and 2) a maintainance nightmare, right? (among other things that are just plain wrong with this "plan".

2 Microphones. Buffer overflow.
I'm getting a buffer overflow error while acquiring data from 2 microphones.
I'm sampling at 22050 S/s with 5000 S/ch.
Within a second I get the error,
"Error 4823 occurred at Sound Input Read (DBL).vi->New.vi
Possible reason(s):
LabVIEW: (Hex 0x12D7) You cannot perform this operation without an active task. Ensure that a task is active and try again. An input task might stop running if the input buffer overflows. Overflow occurs when the data is not read fast enough."
Is there something I can do to fix this? I tried playing with the S/ch and S/s values but couldn't fix the problem. I would think this will become a bigger problem when I try more than 2 microphones. I searched online for a solution to this problem but couldn't find anything that worked for me.
Thanks very much. Examples or any suggestions are greatly appreciated.

ADL buffer overflow crash when loading external module
Hi,
ADL version: 1.5.3
Flex SDK version: 3.5
Flash Builder version: 4.5
OS: Vista 64bit
I have a project that uses various external Flex modules at runtime.
With Flash Builder 4, the Debug Launcher runs fine when compiling on a Windows XP box. The app behaves correctly, no crash.
When debugging the same project on a Vista 64bit using Flash Builder 4.5, all seems fine until I load an external module. At that point, the adl.exe process crashes with the following report:

Hi.
I have a HIL system where I have a Simulink model (dll) running a 1kHz on an RT system with VeriStand. Some outputs from the model is mapped directly to CAN signals. Theese CAN messages are sent periodically typically at 10, 50 and 100Hz.
Looking from the outside, i.e. listening on the CAN interface the messages seems to be sent correctly. However I get a lot of errors shown in the console viewer, see below. The errorcode is -1074388984 which is CAN buffer overflow.
When I disable the the messages which contains parameters mapped from the model the error code reporting stops.
It seems that a CAN message is stored in the transmit buffer after every iteration of the model i.e. every 1ms, then causing buffer overflow.
Is there a setting somewhere to avoid theese error messages or is it a bug? I have no problem with this the I was using the beta.
Regards
RogerHi.
1. Yes, I have used NI Dynamic Test and then later the VeriStand beta. However, my client PC has been reinstalled (Windows XP) meaning that I have a "clean" installation of the released Veristand software. On the RT target I have uninstalled all NI-software and then installed the new softare according to the VeriStand installation instructions.
2. The version of NI-CAN is 2.6.3 (f2)
3. It is NI-CAN 8461 board that are used.
4. My configuration is PXI chassie 1042Q, 8106 controller, FPGA board 7813R ans CAN 8461. I have a custom device configured that uses the FPGA board
5. I have created a blank configuration, added my model and mapped only one signal to the model and this results in the same problem. If I stop the model the error reporting stops. If I remove the mapping the error reporting stops.

I have been receiving the flex log buffer overflow error for a long time. I don't believe it is causing any problem but I'm not sure.
I have Iplanet Web Server 4.1 on Solaris 2.6.
I have changed the LogFlushInterval from the default 30 seconds to 5 seconds.
I am logging a great deal of information
My questions are...
should I be concerned ?
when I get that error is the buffer being immediately dumped to the log file ?
am I losing any log information ?
can I increase the buffer size ?
should I reduce the LogFlushInterval any more ?
ThanksThe error message indicates that an access log entry exceeded the maximum of 4096 bytes and was truncated. You should check the access log file for suspicious entries.
Adjusting LogFlushInterval won't affect this problem, and unfortunately there's no way to increase flex log buffer size. -

Hello,
I modified the very simple example "Cont-Ext-Buff-Cnt" to use 20MHz source clock and connected the signal of my encoder to gate. I can read fine with slow RPM, 1000 or lower. But I do get Overflow problem (-200141) for RPM > 1000. I am using 16 MIO E series card. I changed the BufferSize, Rate, # of samples, but still had the same problem over 1000 RPM. I am using Visual C++ 2005/NIDAQmx8.5/Vista. My processor speed is very good. Here is a snippet of the code I am using. Could anyone help me with this issue, or had a similar situation?

Thank for the reply, and No, the name is not a comment about NI.
I tried your suggestions and still couldn't get it to work. I think the error is Buffer overflow and here what it says: " DAQmx Error: Measurements: Data was overwritten before it could be read by the system.
If Data Transfer Mechanism is Interrupts, try using DMA. Otherwise, divide the input signal before taking the measurement.Task Name: _unnamedTask<0> Status Code: -200141". I think the "E" card uses DMA automatically, and I don't like to divide the signal of the encoder, as I know it worked before using traditional drivers. Here is the code I am using, this code fails when the RPM of the encoder exceeds about 1300 RPM or so (360 Samps/ Revolution). I don't know what I am missing as I would think this example would be very trivial.

Character set Conversion Buffer Overflow Error
Hi,
I have got an issue while loading data from a flat file to a staging table. i.e., Character set Conversion Buffer Overflow. Suppose there are 10,000 records in a flat file, after running control file only 100+ records are loading to the staging table. Remaining are errored out. I think there is no issue with control file because when I load data from different flat file containing same no. of records as the previous flat file, it is loading all the records. what could be the reason and solution for this issue.
Can anyone please suggest me how to resolve this issue.DBNS_OUTPUT is a poor choice for debugging. It has very limited used. And as you've discovered, merely debugging code can now result in new exceptions in the code.
The proper approach would be to create your own debug procedure (or package). Have your code call this instead of DBMS_OUTPUT.
In your debug procedure, you can decide what you want to do with that debug data for that specific program in the current environment and circumstances.
The program that runs could be a DBMS_JOB in which case DBMS_OUTPUT is useless. The program can be called several layers deep from other PL/SQL code.. and you want to know just who is calling your code. Etc.
Having your own debug procedure allows you to:
- create an autonomous transaction and log the debug data to a log table
- write it to a DBMS_PIPE for interactive debugging
- write it to DBMS_OUTPUT
- record the PL/SQL call stack to determine who is calling who
- record the current session's environment (e.g. session_context)
- record the current session's statistics, opens cursors, current SQL, etc. (courtesy of the V$ views)
etc. etc.
In other words, your debug procedure gives you the flexibility to decide on HOW to handle the debugging.
And when you code goes into production, your debug procedure ships with, containing a simple NULL command.. Which means that at any time the DBA can (when the need arise), add his/her debug methods into it in order to trace a production problem.
Using DBMS_OUTPUT is a very poor, and often just wrong, choice.
It is fine for writing a quick test. But when you are developing production code and using DBMS_OUTPUT, you must ask yourself whether you have made the right choice.
And this is not just about wrapping DBMS_OUTPUT. But also wrapping other system calls like RAISE_APPLICATION_ERROR and so on.
