XY-Graph hangs after running continously for 3 weeks

We have an application running on LV 6.0.2 on Windows NT4/2k.
The application is splitted in an overview panel which displays up to 20 graphs (XY-Graphs) and detailed views, which displays only one signal but with further information. The aplication is running continously. If the data source is powered-on data will be acquired. After power-down the data source we reinitialize the XY-Graph and wait for power-on.
The problem is, that the application is working correctly for about 3 weeks and then suddenly the XY-Graphs of the overview panel is hanging - that means we get some data (say 20 min.) and then no more data will be displayed.
The data is formatted in a model-view controller like manner. The special thing
is, that we can format all data acquired for all graphs. The detailed view displays all acquired data as expected whereas the overview only displays some part of it.
Do you have any ideas or solutions for this problem?? We are know restarting the panel after a specified time period and hope that this workaround will solve this error.

I suspect you are runnig out of memory!
The data collected just piles up as it comes in.
How to confirm.
Right click on the task bar and select "Task Manager".
Select the Performance tab.
When you start your app, ther should be lot of memory left over.
Watch this value for three weeks. You should see a steady rise in memory usage until the machine hangs.
If this is a coorect guess, you have two choices.
1)Re-write the app to limit the history that is kept in memory, or
2) Re-boot the machine once every 2 weeks.
See ya back here in 3 weeks,

VISA Write hangs after running OK for a while

VISA Write function (VISA abc W) in my VI runs OK, with a Return Count of 4, for a while (100's to 1000's of times) then it hangs. The Return Count from this function is then 0. The Error In and Error Out show no errors. Clicking HIGHLIGHT EXECUTION shows the output wires from the VISA Write as colored grey, while everything else has normal color.
Clicking the VI red ABORT button, or any of the sub VIs red ABORT buttons, fails to abort or reset the VI even after 20 minutes. Task Manager will stop LabVIEW, but then LabVIEW will not start up again without shutting down and restarting the computer. Changing to a different Windows XP computer and a different PCI-GPIB, NI-488.2 board, as well as reinstalling LabVIEW 7.0, or using a different LabVIEW 7.0 serial number, has not solved the problem.
Thank you for your help.

Thanks for your reply. Attached is a PowerPoint file that shows info on our computer and LabView, and a For Loop
(Slide 3) that runs the VIs addressing one of our instruments (Hart 1590 Super Thermometer). Slide 4 shows the
block diagram that is pretty much as downloaded from National Instruments. The block diagrams for each of the
colored sub VIs contains a sub VI having a VISA abc W function as shown in Slide 5. The only places this VISA
function hangs is in inside the While Loop, inside the yellow Meas. Status. VI or the blue Read Meas. VI. The
Meas. Status. VI sends "new", and the Read Meas. VI sends "tem" to the Hart instrument.
Also attaced are the VIs for the Measurement Status and the Read Measurement. In the course of trying to fix this
problem I've added various time delays of 50, 100 msec, up to 1 sec, thinking that the Hart needed more time to
respond before receiving another command; none of this improved the situation. I added indicators and arrays to
capture the last several strings that were input to the VISA function, but I saw nothing unusual. All I've been
able to determine is that the VISA abc W function hangs as described in my posted message.

ABAP Program gives error after running successfully for few days / months

I have a problem that sometimes my programs start giving errors or does not run at all after successfully running for few days / months.
But, when I copy the same program with a different name (without any changes ) it starts running again.
Yesterday I had another problem. I was sending a request to be transported to Production Client, and the request was not getting transported. But when I changed just the name of the program, It was transported to Production Client.
I can't understand where the problem lies and what happens to the programs after running successfully for few days. All I have to do is just copy that programm into another name and it starts running.
Can anyone help me?
Regards,
SK Daniel

about the transport thing..i had the same problem few months back the reason was, i included a table which is having different package from my program..so wot im thinking is when you creating a different program u might be assigning different package to this new program and this package is same as all the tables included in your program...
regards

My Macbook Pro purchased Dec 2011 has suddenly become very slow after not using for 2 weeks (close to frozen). What is the problem and how to solve it?

My Macbook Pro purchased Dec 2011 has suddenly become very slow after not using for 2 weeks (close to frozen). What is the problem and how to solve it?

Need Help Ye,
boot your MacBook Pro into Recovery mode by holding down a Command key and the R key as it starts up. Once the Mac OS X Utilities menu appears, select Disk Utility. On the left-hand side of the Disk Utility window, select your internal disk’s boot partition (typically called “Macintosh HD”). On the right-hand side, press the Verify Disk button if it’s not greyed out; if it is greyed out, or if it reports that errors were found, press the Repair Disk button. Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu to restart in normal mode. Is it still very slow?

Can I update my RAM in macbook pro after having it for 2 weeks?

I just got a MacBook Pro and I want to know if I can update the RAM from 4gb to 8gb after having it for 2 weeks or if I have to buy it with the 8gb RAM already installed

Assuming that you have a current model MBP, you can actually install up 16 GB RAM. The specifications are: 204-pin PC3-12800 (1600 MHz) DDR3 SO-DIMM.
The two best sources for Mac compatible RAM are OWC and Crucial. If you need instructions, go to the OWC web site and select the appropriate installation video. You will need a #00 Phillips driver to perform the installation.
Ciao.

My brand new back up drive is connected but now time machine has disappeared after working perfectly for a week. - no icon, not appearing as an option to save to - have rebooted everything a few times.

My brand new back up drive is connected but now time machine has disappeared after working perfectly for a week. - no icon, not appearing as an option to save to - have rebooted everything a few times.

It's not clear whether you were able to do any backups to this drive at all. If not, it's probably not formatted properly. See #5 in Time Machine - Frequently Asked Questions for instructions.
If you did get any successful backups, there may be a problem with the drive, or the backups may be corrupted. Try to repair the backups, per #A5 in Time Machine - Troubleshooting.

Error 10846 after running VI for a day

I am trying to develop a program that acquires data continuously from 9 analog input channels, then processed the data to extract the mean, max, min for each signal and do some calculation and then store the data in a spreadsheet every minute. The VI works fine if I run it for a short time (less than 5 hours) but if I tried to run it for a long period (an all day), I get an AI error 10846. If I ignored the message error and keep running the program, the error message 10846 keeps appearing and every thing in the VI seems slowing down. If I restart the VI without restarting the computer, the VI will run but the same message error 10846 will reappear after a short time. So I have finally had to stop the program and restart the co
mputer so that the VI reruns normally. The VI is running at a scan rate = 1000 scans and a scan to read = 2000 scans, the buffer size is set up to 20000 scans. I tried to increase the buffer size up to 100000 scans and increase the scan to read up to 10000 scans but the message error keeps appearing. If I look at my scan backlog, for the first couple hours, it is equal to 0 and after that, for no reason, once in a while, the scan backlog show a value different of 0.
I do not have really a lot of experiment with Data acquisition system and I am not sure to use the correct values of those parameters. But at the same time, I do not understand why the VI is running fine for couple hours and then crashed.
Concerning the system that I am using, my computer is a 1 GHz Duron Processor running Windows 98 with 120 MB of RAM and I used:
NI software = LabView version 6.1
DAQ card = PCI-6071E
I attached my code for the ones who will have time to run it.
If anyone can offer some wisdom on
that it would be greatly appreciated.
Thanks
PS: I am also wondering if the problem could come of my computer or hardware I am using?

Right off hand, I would say that the fact you have to restart the computer to recover is very odd indeed--and troubling. Have you tried to run any of the continuous acquisition examples that ship with LV to see if they exhibit the same behaviour? Also, is the computer on a network? If so, try unplugging it and see if you still get the problem. Finally, when the thing is slowing down, what does the computer's overall CPU utilization look like?

Wifi hangs up on start-up, and computer hangs after using internet for 5 min.

HP Touchsmart tm2, using Window's 7 64-bit. There are no error messages popping up, but what happens is I start my computer, and my wifi/internet connection icon seems to freeze while loading possible internet connections. If I turn off my wifi and then turn it back on using the button on the side of my computer, it seems to work correctly, then.
But, when I get on the internet, no matter what site I go on to, my computer will just hang up after being online for at most 5 minutes. Mozilla Firefox will go into a Not Repsonding mode, and I can't minimize it or click/open any other programs. CTRL+ALT+DEL doesn't work, and when I hover over any icon, nothing seems like it's recognizing my mouse. The mouse moves, though, and the time even keeps going (it'll change from 9:13 to 9:14 and so forth).
It ends up figuring itself out, though, after another 5 minutes (literally an entire 5 minutes) and then seems to work okay.
Recently, I updated CCleaner to the newest version, cleaned out my internet cache, defrag my computer using Defraggler, used CClean to also wipe by free space, and updated Avast! Antivirus to the newest version and ran a full virus scan with no threats detected... :/

Hopefully No real Damage was done.
A Surge Protector works fine with items like Lights, Lamps and small electrical items. Where the problem arises is with Computers, which are precision electrical devices. The only real protection is a Battery Backup like an APC.

When there is a Power outage no matter what the source. can also create tremendous Power Surges. This can happen when the electricity is turned back on and can cause frying all of your Electrical Appliances.
Having an APC will save all of your Computer Equipment including your Modem, Router, Printers, Scanner, Computer, as well as Phone lines.
A simple Surge Protector simply isn't enough protection and especially the cheaper models.
Here is the simple way to check and see if your equipment is still operable.
Turn your Computer clear OFF and pull the Power Plug
Pull the Power from both your Modem and your Router.
Wait a minimum of 5 minutes. After the 5 minutes Plug in your Modem and wait a minimum of 3 minutes.
Now plug in your Router and again you must wait 3 to 4 minutes.
Now you can plug in your computer and restart it and don't touch anything. If your computer starts up then you got lucky If not you will probably need to take it to the genious bar at your closest Apple Store. Chances are that your computer has components that have been fried from the power surge. Good Luck and hope your computer restarts.

After being away for two weeks my iMac wont send my Orange mail.

After being away on holiday for two weeks my iMac wont send my Orange mail. I get the message "The server “smtp.wanadoo.co.uk” refused to allow a connection on the default ports."
I have not changed any setting, the email sends if I login to Webmail, so the account itself is valid. The iMac mail downloads my email perfectly as normal. Using Mac OS X 10.6.8. Email address is one I have used for almost 10 years without any problems.
It is a POP3 account using default ports with no authentication or SSL. Have tried different ports (e.g. 26), putting password authentication on, but nothing works.
Any ideas?

Fixed it. Played about with the port numbers and got a more detailed message:
Client host blocked for spamming issues. OUK104_102 Ref http://csi.cloudmark.com/reset-request/?ip=nn.nn.nn.n. Select a different outgoing mail server from the list below or click Try Later to leave the message in your Outbox until it can be sent.
Went to Cloudmark and got the IP reset. Took an evening of work but worth it.

hi!
If I use DriverManager to get my connection, will it still inherit the
transaction attributes defined in EJB? Will it auto-commit?
Thanks!

You should either get the db connection from a DataSource or use

Error -1074360293 (IMAQdx Timeout) after running acquisition for some time

My vision application in LabVIEW does several acquisitions and processings successful but then the acquisition (grab) suddenly fails with a timeout error (-1074360293, IMAQdx: Timeout). The error does not happen when only acquiring the images.
After the error happened no acquisition is possible. Even when LabVIEW is closed MAX returns a timeout error. Only rebooting helps.
some Hardware Details:
3 FireWire Controllers (1394a)
3 Cameras connected to the first two controllers, one to the third (7 cameras total)
Mode for all cameras: 1280 x 960 Mono 8 7.50 fps
The bandwidth for a FireWire controller is sufficient. (Three cameras on one controller run without any problem.)
The memory consume of the application is raising short before or after the error occurs. But I did not find out where exactly.
Before the error happens some minutes until one and half an hour pass.
More details will follow.
Is there a specialist in FireWire or in vision who can help?
Greetings,
shb
Solved!
Go to Solution.

Changing the driver to this one seems to solve the issue:
"OHCI-compliant 1394 Host controller (legacy)" (in German: "OHCI-konformer 1394-Hostcontroller (alt)")
With this driver the test has run for more than 66 hours without throwing an error.

Error after running Projector for a while

I run a projector in a kiosk. When being used there is no
problem, but at night if it is not being used for a bit I get one
of two errors
Faulting application dirproj.exe, version 10.1.0.11, faulting
module iml32.dll, version 10.1.0.11, fault address 0x000113d7.
Faulting application dirproj.exe, version 10.1.0.11, faulting
module iml32.dll, version 10.1.0.11, fault address 0x0000be06
These happen at various times and doesn't seem to be a
pattern for when it is one or the other. Any help is appreciated

You would need to make another application to monitor the
status of the
main one. Xtras like BuddyAPI will help there. It is easy to
check if
an app is open, and if not, open it.
Or you could have the main app write out a file every 5
minutes or so.
Have your monitoring application check the file date on that
file. If
it is >10 old, then that means that the main app is locked
up or
crashed. The monitor app can close it then re=open it.

DAC is running contineously for SIL Service Request Fact

Hi All,
Help is needed.!
I am using DAC 7.9.4.
I have started Incremental Load for the DAC.
It went fine for first few runs, now it is showing that SIL Service Request Fact is running. This is running from last 4 days continuously.
I have alreday checked the log files which are there in the folder Sessionlogs,Workflowlogs & DAC >> Log.
I am not able to find out the error.
The session log file has last lines as

Please Help me to solve this problem.
Its very urgent.
Thank you in Advance.

Hi All,

Network hangs after streaming music for a few minutes

I have a strange network problem when I stream iTunes music from my MacBook Pro, via an Airport Extreme base station to an Airport Express with speakers connected. The MacBook and Airport Extreme both have a wireless connection to the base station.
After the music has been streaming for a few minutes, it is no longer possible to access the internet or local network from the MacBook (e.g. with Safari, Mail). Even a ping to my router fails to respond. However, the music continues to play over the remote speakers all the time, so there is apparently a network connection to the base station.
Simply stopping iTunes does not fix the problem, but if I turn the Airport connection off and on again on the MacBook, the network comes back to life for a few more minutes. I can access the Internet via the Airport Extreme using my iPod Touch, so the base station must still be working. When I am not using iTunes streaming, the network is fine.
I tried replacing the Airport Extreme by another Airport Express, so that I had an Airport Express as the base station and another Airport Express connected to the speakers. The problem no longer occurred, even though the Airport Express and Airport Extreme had the same firmware version (7.4.1) and were configured with all the same settings. This leads me to think the problem is with the Airport Extreme.
I also tried connecting the MacBook to the Airport Extreme using an Ethernet cable, instead of the wireless connection. With this configuration, the problem did not occur.
Any help would be appreciated.

I have the exact same problem. My entire computer stalls for a while until the music comes back. I've tried streaming the music through Airfoil instead of through iTunes but the same problem occurs, although it seems to be less frequent through Airfoil.
