Ring buffer overflow message (Solaris 10)

When I disconnected the Ethernet cable from the back of our Netra 210 , the console would show this messages
# telnet <ip>

Could anyone tell why these messages are keep on coming on ??
-Amit

'su' is one of the serial drivers. I'd expect that message if the serial port is attached to something that is screaming data at the machine. One of the buffers that is examining the data is overflowing.
Is something attached to one of the serial ports?

IPVC-3540-MC03A "ring buffer overflow!"

My IPVC-3540-MC03A module in my IPVC 3544 lost communication to my network. I consoled into it and all I am seeing is the below message over and over:
"interrupt: panic: netJobAdd: ring buffer overflow!"
It will not even allow me to use the help command. I have yet to reboot it, since I have a pt to pt H323 Video Conf. currently going on. Any advice as to what to do from here. I believe I will have to reboot it to possibly have it recover and then upgrade the firmware(if possible) to ensure that this does not happen again.

Upgrade your MCU to veriosn 3.2.113 or higher.

FTP buffer overflow in Solaris 10

ftp session starts but it is not transferring files. The problem is showing in machines running Solaris 10. It was perfectly working till last week. All of a sudden one-by-one servers started showing this problem. Also let me know how to view ftp logs separately ?
Thanks

This message I gets when I starts any file transfer using ftp.

Log buffer overflow

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 ?
Thanks

The 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.

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
Thdyn...Report für den Extraktoraufruf...I_T_FIELDS...Table IT_43[16x60]TH058FUNCTION=

<...tabi         = Not allo......S_CURSORL...SAPLRSA3...LRSA3U06...SAPLRSA3...
During dump creation the following occurs:
"...SAPLSPIAGENTCW...CX_DYNAMIC_CHECK=...CRSFH...BALMSGHNDL...
DBIF_RSQL_INVALID_RSQL...DBIF_RSQL_INVALID_RSQL...DB_ERR_RSQL_00013...

INCL_SEND_TO_SAP...GENERAL_EXC_WITHOUT_RAISING...GENERAL_ENVIRONMENT...
GENERAL_TRANSACTION...GENERAL_INFO...GENERAL_INFO_INTERNAL...
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 AM

Hi 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.

Script running in the background and buffer overflow

Hi,
I have written a script that is supposed to be a background process, which will check every 5 minutes if given person is logged in on Skype.
The script does it basic job (alters me when given person is on Skype) but when I try to quit it (see code below, first display dialog inside on idle handler) it does not quit. Instead it displays "buffer overflow" or "stack overflow" error message (I am not certain how to exactly translate the error message - it is not in English as I am not running MacOS X in English). Also on rare occasions it displays another error message about terminated connection.
Any advise about how get rid of these errors would be greatly appreciated.
I have saved the script as an application and I have added to Contents/info.plist the following:
Application is agent (UIElement) = true
Here is the applet code:
global interval
global _path
on run
set _path to POSIX path of (alias ((path to me as text) & "Contents:Resources:sound.aif"))
set interval to 300
end run
on idle
tell application "System Events"
set _run to (name of processes) contains "Skype"
end tell
if _run = true then
tell application "Skype"
set _Calls to send command "SEARCH ACTIVECALLS" script name "cal"
end tell
if _Calls = "CALLS" then
tell application "Skype"
set Lstat to send command "GET USER " & "user_nickname" & " ONLINESTATUS" script name "stats"
set AppleScript's text item delimiters to " "
set status to text item 4 of Lstat
if status is "OFFLINE" then
--do nothing
else
do shell script "afplay " & _path
tell me
activate
display dialog "user_nickname is on Skypie" buttons {"OK", "Change interval", "Quit"} default button 1 giving up after 60 with icon note with title "Skype check"
if button returned of the result is "Quit" then
quit
else if button returned of the result is "Change interval" then
display dialog "Enter new interval in minutes:" buttons {"OK"} default button 1 default answer "5" with title "Skype check"
set interval to ((text returned of the result as number) * 60)
end if
end tell
end if
end tell
else
-- do nothing
end if
else
-- do nothing
end if
return (interval as number)
end idle
on quit
quit
end quit

Delete the following code:
on quit
quit
end quit
The purpose of the 'on quit' handler is so additional instructions can be executed when the script is told to quit. If desired, 'continue quit' can be part of the handler to call the normal quit command; without the 'continue', the script just repeats the handler over and over with no exit, which causes the overflow.

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
Unfortunately, though, I have not gotten a response to my original post.

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.

CAN buffer overflow

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
Roger

Hi.
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.

Buffer overflow

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).
Attachments:
Generator-Accelerometer New.vi ‏636 KB

Here 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.

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.
Nikhil

This has been answered before:

DBMS_OUTPUT.put_line buffer overflow

Hi all
I am taking some values into a cursor and updating a table with those values, and catching the exception in the exception block
EXCEPTION
WHEN OTHERS
THEN
sqlm := SUBSTR (SQLERRM, 1, 100);
sqlc := SQLCODE;
DBMS_OUTPUT.put_line ( 'Error Code : '
|| sqlc
|| ' Error Message : '
|| sqlm
|| ' : aaa:: '
|| aaa_rec.recid
Here the problem is the data which i am updating its huge(5 million records), i am getting the error for the exception block as Buffer overflow( After I set it to the buffer value to maximum i.e 1000000), how can i avoid this problem, i am not supposed to use utl file package, Can u be a little brief in ur answers
Thnks in advance

1000000 is not the maximum size:
http://download-uk.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_output.htm#CIHEGBBF
There used to be a maximum setting of 1000000 (in practice nearer 600K) in earlier versions of Oracle. Perhaps you are using one of those and forgot to mention it?
In any case, why are you using a debugging tool for error handling?

How to check udp buffer overflow in solaris10

Hello All,
We have developped a C++ application which uses connection based udp socket for transfering the data between two solaris10 machines. The data transfer takesplace for every 20 min and continues for about 1 min. The total no of udp sockets i am using is more than 1200. During the time of socket creation i don't set the send and receive buffer size, so the default parameter configured in the system will be considered.
In certain cases the receiving end application does not receive any data, but the sender continues sending the data, this i could see from the snoop. Also the write operation doesn't fail in the sender side.
From the snoop command i could see the time interval between the packets sent is 30microseconds. So there could be possibility that udp buffer may overflow.
Does anybody know the solaris system command to find the udp buffer overflow?.
