GPRS services suddenly stop working after some time abt 4 hrs.Airplane on off solves it

I am using a factory unlocked iPhone 4 GSM in India. Iam currently using it on airtel network 2G services i.e GPRS services. Now the problem I have noticed is that the GPRS services suddenly stop working after some time say about 4 hours. Then what i do is to turn airplane mode on and then off or restart the phone and GPRS starts working. Agan after some time I have to repeat this exercise. Please help soon. This is happening since the time i bought this phone i.e from past 20 days. I have tried allpossible network settings and resetting network but nothing helped. everything else is working perfect.

Hi Syed,
I have also started facing the exact same problem since the past few months with my docomo service.
Earlier, EDGE / GPRS used to work just fine from my workplace where the network was good.
But recently, I got my iphone replaced, due to a network problem, from an apple store in indianapolis, and also upgraded to ios 5.....so not sure now whether this intermittent EDGE / GPRS outage is due to the new hardware or the new OS.
Did you upgrade to iOS 5 and did it help?
PS: iOS 5.0.1 also doesn't seem to be helping, I still need to restart the phone to get EDGE / GPRSt to work.....will try out the airplane mode thing....at least that shouldn't take as much time as a full reboot.
Regards,
Hemant

Multitouch Gestures Stop working after some time in Mountain Lion

I have a problem with Multitouch Gestures on Macbook Pro, using Mountain Lion. After some time 3 thinger swipe to left/right stops working. The only thing that helps to solve this problem is making a restart. Are there any other ways to get rid of this problem?

Me too. My iMac and MBP same here. Having graphics glitches when playing games neither in Mac or Bootcamp with Windows. Sometimes screen even slashed into half and freezed. Wake up from sleep also have graphics issues, like I need to use the crusor to oaint out the grey login screen, if not, it will stay white. Slowly moving the crusor will paint back the grey background.

Replication DS6.2 - DS5.2 stops working after some time

Hello!
After weeks of unsuccessfully trying to solve a replication problem, I hope that someone of this forum can give me a hint.
I have 2 masters DS5.2 and two masters DS6.2.
Replication is working fine for some days. E.g. last time the replication was working until 29.11.
But at some point the replication stops working and I get the following errors in the errors log:

I tried to reproduce the problem.
At the moment everything works fine and I can do many changes.
But I know that there is somewhere a problem and the replication will stop working again in the next days.
Can you give any advise?

Beate

Here is an explanation of the failure:
1. Prioritized replication was introduced with DS6.0;
2. When a suffix at a DS6 instance is initialized from a DS5 instance, and then an operation is performed at the DS6 instance that uses prioritized replication, replication fails;
3. By default, password policy uses prioritized replication to propagate auth-failure-lockout state updates (e.g., adding a pwdFailureTime attribute value on a failed bind attempt);
A work-around:
Disable DS6 supplying auth-failure lockout state using prioritized replication. In any password policy having auth-failure-lockout enabled, set
pwdIsLockoutPrioritized:FALSE
Note that DS6 enables prioritized lockout by default, in particular, it enables this feature when migrating a password policy received from a DS5 instance. Hence, for this workaround to be effective, the prioritized lockout feature must be disabled in any DS6 password policy that has auth-failure lockout enabled, which could include:
1. The default password policy at any DS6 instance (cn=password policy,cn=config);
2. Any password policy originating at a DS5 instance, including those in data imported into a DS6 instance, received via replication total update initialization, or added at the DS5 instance subsequent to the DS6 instance initialization;
3. Any password policy added to a DS6 instance.
Additionally, do not set any prioritized replication rules for other attributes.
It is possible the bug can still be triggered in the case of a DS6-only topology that was initialized from DS5 data.
Contact Sun support for the status of a fix for the bug. The CR is 6645742.

On Windows 8, some widgets, such as the menu button near the upper right, stop working after some time, and functionality is restored by rebooting the PC.

I use the latest releases of Firefox as they become available on a Windows 8 PC. Firefox works properly, usually for a few hours, before annoying problems manifest. The problem I'm addressing here is some widgets, including some Firefox widgets and isolated widgets (such as buttons and pull-down selectors) in some websites stop working. In Firefox, the Menu button (the three stacked dashes icon) stops working. And the Download arrow sometimes stops working also. Sometimes, sub-items such as Print stop working. For some pull-downs, the up and down arrow keys might still work even though I might now be able to select with the mouse. Closing and reopening Firefox usually restores some functionality. However, I usually have to reboot the PC to restore all functions which stopped working. Then I am good for usually a few hours again. Another annoyance, which others have addressed, is the eventual appearance of Chinese-looking characters on the tab labels bar across the top. Restarting Firefox gets rid of these for the time being. Thanks for investigating.

hello, maybe that's an issue with hardware acceleration - please try [[Upgrade your graphics drivers to use hardware acceleration and WebGL|updating your graphics driver]], or in case this doesn't solve the issue or there is no new version available at the moment, disable hardware acceleration in the firefox ''menu ≡ > options > advanced > general'' (that setting will take a restart of the browser to take effect).
the oriental characters are a displaying flaw caused by the mcafee site advisor extension - please try to disable or remove that in case you have it present until there is an update by mcafee that can fix the problem.

Web Proxy sessions stop working after some time (ISA 2006)

Hi guys,
we have been using ISA 2006 with Web Publishing Rule to provide access for mobile phone to corporate Exchange via ActiveSync for years. The issue occurred roughly one month ago.
After some period of time (usually it happens once or twice daily) ISA stops to accept connections from the mobile phones. There are no errors on client devices (they don't get new mails). In Sessions tab I see that only SecureNAT sessions from phones remain,
but no Web Proxy sessions any more. There are no errors in Event Viewer and I didn't find anything strange in diagnostic logs.
I've created one more Web Publishing Rule with the same Web listener as for ActiveSync rule for OWA. The intersting thing that ISA still allows access to OWA when issue occurs. Looks like the problem with Web Proxy filter.
After OS restart ISA starts working normally.
I have ISA 2006, sp1, version 5.0.5723.514 installed on VMWare VM with Windows 2003 SE sp2.
Do you have any ideas?

Hi,
Does this issue still exist? If so, you could try to collect logs from devices to find more information.

Internet stop working after some time on line ....?

Hey all ....!!
I have a bit of a problem, i live in South Africa, and have wireless internet, with a desktop modem connected to my iMac using a ethernet cable, and using the network settings in system preferences.
I have been using this setup for some time now and have had no problems, till a few days a go i did a apple update, where there was a security update and i downloaded it and installed it and all is good then a few days after that i was on MSN chatting to a friend and the after maybe 30mins or so the net gave me a strange error saying that the remote computer as terminated the connection, after witch i reconnect with no problems, then maybe 30mins later it dose it again.......
I then had a look at my settings and i found a option that you tick...... Disconnect if idle for 30 mins but it is not on... i turned if off long time ago ... then i thought maybe it was msn... so i quit msn and played on the net for some time it did it again and again and again.
I am getting a little bit upset with it ...... i have phoned the company that host my internet but the is not problem with the service and if i tell the help desk there about the problem and tell them i have a iMac they think i am talking about a burger... sorry not a nice to say but not many people that work there know what a iMac is ...!!!!
please please can someone help me in anyway at all.... please ....?
thank you.
iMac, 1.8Ghz Intel Core 2 Duo, 512mb, 160Gb Mac OS X (10.4.10)

I have the exact same problem... please there must be
someone there at Apple that knows something about
this... what can we do??? Wait for Leopard... ?
OK so I tried to fix the problem myself....... I unplugged the modem and retyped all me settings again..... plugged back in and then tried again it looks like i might have worked..... you should try that...... i also phoned the iStore, Someone told me that i must go to my disk utilities and do something there but that got me a bit worried..... I don’t know iMac's all that well yet and don’t want to play with something i know nothing about........ but if that dose not work then i will phone her again and post what she tells me to do ...!!!

Why does ServerSocket stop working after some time?

Hi to all.
I have a following problem:
I wrote a multithread application that uses sockets ( TCP ), and use it to transfer some objects between computers in VPN.
It all works just fine, except that sometimes my server socket ( implemented as a separate Thread ) just stops working, and other computers cannot connect to it...?
I didn't specify setSOTimeout(), and did all Exception catch-ing in the thread.
Today, I had some >50000 connections in about 5 hours, and than it just stopped! My server socket stopped accepting any connections...
I restarted my application, and everything worked again properly...
Does anybody know why is this happening?
Please, any suggestion is appreciated....
Thank you.

Hi, thank you all for answering me.
@baftos:
I didn't specify any backlog parameter value. 50 connections at a time seems more than enough for this application... ( Are you sure that 50 is the default value )
I never have more than about 40 connections simultaneously opened, and yes - each one is a separate thread.
@dannyyates:
You're rights, I should have provided some code.
Here it is:
public class Server implements Runnable
ServerSocket serversocket = null;
Socket clientSocket = null;
continueWorking boolean = true;
    public void run()
            startServer();
    public void startServer()
        try
             serversocket = new ServerSocket(3344);
        catch (IOException e)
             System.out.println(e.getMessage());
     while ( continueWorking==true )
         try
              clientSocket = serversocket.accept();
              Worker Worker = new Worker(clientSocket);
              new Thread(Worker).start();
         catch (IOException e)
              System.out.println(e.getMessage());
        System.out.println("The server is shutting down...");
class Worker implements Runnable
    ObjectInputStream obj;
    Socket clientSocket;
    public Worker(Socket clientSocket)
         this.clientSocket = clientSocket;
        try
          obj = new ObjectInputStream(clientSocket.getInputStream());
         catch (IOException e)
              System.out.println(e.getMessage());
    public void run()
        Object object;
     try {
                      try
                           object=(Object)obj.readObject();
                                               // do something with object....
                      catch (ClassNotFoundException e)
                           System.out.println(e.getMessage());
                    catch (Exception e)
            obj.close();
            clientSocket.close();
     catch (IOException e)
    catch (Exception e)
    }What I don't like here is the constructor of the Worker. Could this block the server?

Entity Beans stop working after some time

hi,
I am facing this strange problem. I am devloping a Learning Management System. Once I deploy the app it works profectly fine. It calls all the session and ejb beans perfectly.
I am using the sun one 7 PE and J2EE 1.3. After the product has been deployed for a couple of hours, and i re run the application, it gives a null pointer exception. The session bean cannot connect to the entity bean.
I am using mysql as db and have a pool defined.
Is there a connection time-out problem or some problem with the entity bean, because the session beans work fine even days after deployment, but entity bean stop functioning in a couple of hours.
Some help needed !

Have you looked at the server.log to see if you have any other clues to the point of failure?

Expose keys stop working after some time

Hi,
I am experience some failure of my Exposé keys after a certain amount of time without rebooting the system. (~2 hours+). Usually you can show the Desktop by pressing F11, show all application windows with F10 and so on. After the system booted everything works like I would expect it, but then the keys doesn't react anymore.
F11 seems to send the command to the foreground application, instead to the OS which causes fullscreen presentation for the firefox browser.
I can fix the issue temporarily by restarting the dock, however after a hour the problem reappears. That is very annoying and frustrating.
What can I do?

Mail accounts stop working after few time or sleep

Hi everyone. First at all sorry about my english.
Since few days ago, and probably after run onyx, im experiencing a bug in Mail.
When i start mail, everything its ok. Its works perfect.
But, after maybe 2 hours running (usually i have mail on autostart), i see that all my acounts have the triangle on it.
I click on the triangle and tryed to reconnect all accounts but it does nothing. All of them still not working.
I run the test and all accounts have the red mark of error.
It usually happends when i awake the macbook after sleep.
It has easy solution. Close mail, and open mail again and is ok, everything working normaly, but after some time i have the same problem.
Any suggestions?
Thank you.

If I first delete the accounts, doesn't all the mail I've already got get dumped?
Could I avoid this?
How do I troubleshoot first? It works so well that I've not had to do this.

If I restart my computer, USB stops working after 3 days and won't respond until I restart
If I log off it works for like a couple of hours and then stops again...
I'm sure this isn't what you want to hear but unless you really are using your laptop 24 hours a day, is there any reason why you don't just shut it down and reboot when you're ready to use it again? I have to wonder how many other MacBook Pro owners potentially have the same problem but when they quit computing for the day, their computers quit too.

GPRS services suddenly stop working after some time abt 4 hrs.Airplane on off solves it
