Collaberation Suite Stops Responding after some time

I have been testing collaberation suite on linux and have everthing working to 100%, but it seems that after a day or so of running it stops working. The listeners stop and I cannot access any of the services until I restart them. The configuration is:
Dual Intel 1.7 gighrtz Xeon Pentiums with 2 Gig of ram. Could it be I need more ram?
I don't have, but 3 users just for testing so it's not highly demanded upon.
Thanks for you Help,

Hi,
What O/S are you using, and what version of the kernel?
Thanks and Best Regards

Firefox stops responding and some times dose not start when clicked on alot!

fire fox 9 stops responding for long periods and some times dose not load when clicked on. Also please note fire fox refuses to load the comments section on Yahoo.com under the news tab. The little wheel on the bottom of the page just spins and spins and never loads this area of the page.
I think i know why but wonder since i have had issues with fire fox in the past with the whole not responding and load issues.

Firefox which stops responding after some time is a BIG problem. You're not the only one. The problem seems to be with sites which require Java. The problems I seem to have spotted is this : You visit a web site which needs Java so Java asks Firefox for the amount of memory needed and this is lent to JAVA. However, when you leave that web site, Java is naughty in that it doesn't give back the memory borrowd. Firefox then has to consume a lot of memory to the point that the whole computer system grinds to a halt as you have run out of memory.
Search in the forums for high memory or RAM and you will see many threads. In fact, when you first install Firefox it will ask if you want to send anonymous data about the memory usage!!

BC4j/JSP Application not responding after some time - when deployed on 9ias

Hi,
We are using BC4j/jsp application on 9ias. The application is not responding
after some time. We have installed 9ias on PIII(384MB RAM). We tried to accesses
with 10 users, and server is not responding to BC4J/JSP application.
However the server could able to publish the JSP pages with standerad JDBC code even after that.
many many thanks in advance
null

When the application deployed by BC4J/JSP not responding, does the sample JSP application still works? i.e. does any other application respond? Does 1 user respond? Is the database source (JDBC), running Oracle 8.1.7? What is the platform running the database (e.g. local NT database)?

<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Is there any mechanism that cleans up these connections (back down to the initial or some other minimum I would guess) or do they hang around until either the app server or database shuts down?<HR></BLOCKQUOTE>
There is currently no mechanism for reducing the connection pool size after a period of high activity. Recently this has been frequently requested and as such will be implemented in the next production release.
<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>We have verified this in manual testing. However, when the load tool script exits it doesn't seem to release resources. We know this because we keep seeing our database connections go up and up as more tests are run. Further, we also seem to see more than one connection per "virtual user". For example, when I connect 5 users to the app in manual testing, I get 5 connections. But, when we run a test using the tool, we get 395 database sessions for 200 users. We are having a bit of difficulty understanding why the behavior is different.<HR></BLOCKQUOTE>
Assuming that the you are performing your manual testing against the same instance of the application on which you are performing your load testing, I would assume that the connections are being released to the pool at the end of the request. One possible reason for the approximate 2:1 ratio between connections and virtual users may be BC4J's use of internal connections. What version of BC4J are you using?
BC4J requires an internal connection to support state management and spill to disk. The internal connections are pooled with the transaction connection and only held for the duration of the persistence operation. However, if the web server is very busy then a large number of synchronous persistence requests may be received which would explain the eventual 2:1 ratio in the pool's high water mark.
If the user start times and think times are staggered in order to reduce the incidence of synchronous persistence requests does the ratio of connections to web sessions stabilize at some lower number (i.e. 1.5:1)

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.

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.

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.

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?

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.

WLSE 1030 not responding after some time

Hi,
I have a wlse 1030 with 2.13.i have done all the configurations.after sometime itstopped responding to console access,ping etc.so,then i restarted after restarting again it working fine for some time.and then again the same problem is coming.what could be the problem.And while restarting it crashed two times then i recovered with the cd.
and it is not detectinf keyboard,mouse.some times it is detecting.
pls help me i am unable to resolve this from a long time.
regards,
subash

Below are the possible reson for that telnet issue
Telnet is disabled or configured incorrectly.
The WLSE cannot recognize host names.
If you are not using name recognition, slow or non-existent telnet interaction is an expected problem.
Make sure that Telnet is disabled by default. SSH is enabled by default.
Recommended Action
If the problem is not the network, perform the following steps. Connect to the console port if you cannot Telnet to the WLSE.
1. Check the Telnet settings to be sure Telnet is enabled and configured correctly. For more information, see the following
To check the Telnet settings, or to enable or disable Telnet on specific domains or IP addresses, use thetelnetenable CLI command. For more information on this command, see the User Guide for the CiscoWorks Wireless LAN Solution Engine, Release 2.13. You can access a PDF version of this guide by clicking View PDF in the WLSE's online help
To enable or disable Telnet on individual ports, use the firewall CLI command. For more information on this command, see the User Guide for the CiscoWorks Wireless LAN Solution Engine, Release 2.13. You can access a PDF version of this guide by clicking View PDF in the WLSE's online help
2. If you have specified hosts using the telnetenable CLI command, make sure the host from which you are attempting to Telnet is on the list.
3. If you are using a DNS server, perform the following step:
Configure the system to use a functioning DNS server by entering:
# ip name-server ip-address
where ip-address is the IP address of the DNS server.
If you are using the import CLI command, proceed to the next step.
4. Verify that the system can get DNS services from the network by entering the following command:
# nslookup dns-name {hostname | ip-address}
where dns-name is the DNS name of a host on the network that is registered in DNS and hostname andip-address is the same IP address specified in 2. The command returns the IP address of the host.
5. If the system cannot resolve DNS names to IP addresses, the DNS server it is using is not working properly.
Resolve the network DNS problem, then continue.
6. If you are using the import CLI command to resolve host names, verify that the WLSE can resolve host names by entering the following command:
ping hostname

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 ...!!!

Webpages stop loading after some time across all browsers

I have come across a problem that 2 of the users that I support have been experiencing recently and I am trying to figure out where to begin. They will be able to use the internet, access webpages and everything for some time till at one point seemingly randomly all web browser connectivity becomes stuck at the dialog Connecting and eventually times out trying to connect to the host server. Yet other forms of internet access, like ping and telnet, work just fine at this point. Basically it seems that all traffic going to ports 80 and 8080 times out and I have pulled the logs where I believe this happened and pasted them here:
http://pastebin.com/VPSPwyBe
A temporary fix for this so far is a quick reboot and everything behaves normally for sometime till web access drops and another reboot is required. This is true across all browsers, IE, Firefox, and Chrome on a MacBook Pro Retina 15" running OSX 10.9.4. I have tried fresh installs of all the browsers and switching to a different OS X user account and still have the same problem. I have also tried to flush the DNS using the terminal and that has had no effect. There are no proxies involved and resetting the wireless adapter produces no results. Going to keep searching for some other steps to try to fix this and will keep this thread updated.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

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?

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.
