JNDI Connections Hang Under Load. Is this a bug ??
Hi
We are using Oracle application server and the Oracle Directory Server. I have a simple servlet making JNDI calls to fetch an attribute, under load JNDI calls are hanging creating a large back log of threads that won't go away till the application server crashes. We are using the Sun Hotspot VM 1.3 on Solaris.
I noticed on this forum that several other people have had this problem. Is this jndi limitation or bug ? Is there a known fix for the problem ? It looks like under load even though directory server is up and running alright, serveral JNDI threads hang waiting on a monitor.
thanks in advance
Raghu ..
Hi Raghu,
I'm interested in this issue. I wanted to know a few things
1. Are you using a pool of servlet instances or a single instance for all requests.
2.In your servlet are you directly calling the jndi lookup, if so can u pl.provide a snap shot code of that.
3.What is the load, at which your application getting failed.
4.Have you implemented any thread safe mechanisms like implementing SingleThreadModel, or using synchronized service method(which actually should not be done)....
let me know the above details,,
Thanks

Cache and/or Connection problems under load
I have a Kodo web app that's been running just fine in
production for many months now. However, recently the web
traffic has shot up by a huge amount, literally overnight.
But unfortunately, it's caused the app to fail very ungracefully
under the strain.
It's been a crazy few days, and I haven't been able to do
very much analysis because of higher priorities. But from
what I have been able to gleen, it now looks like Kodo is
the most likely culprit. From what I've read in other messages
here, it appears others may have been experiencing similar
problems.
My environment: Redhat Linux 8, Postgres 7.3.4 with the
included JDBC3 driver, Apache 1.3.x, Tomcat 4.1.x and the
webapp connector. Similar behavior was seen with Apache 2.x,
Tomcat 4.1.x and the JK2 connector (that was on the new machine
I setup to handle the new traffic, which, of course, died the
night before).
As I mentioned, this app has been running reliably for
months with no problems. But when placed under heavy load,
it appears to get into some sort of pathological state where
it slows down dramatically (asymptotically?) to the point where
it's effectively locked up. In one case, where the app was
left running for several hours in this state, requests were
taking 90 minutes to complete (normal is 1-5 seconds).
From what I can deduce, there seem to be four things
going on, three of which have been mentioned in recent threads
here:
1) Excessive memory consumption. When the app is
operating normally, I see fairly flat memory usage for
the JVM process. Under load, the JVM steadily expands
until it hits its heap limit. I've gotten OutOfMemory
exceptions with a heap size of 350MB, which should be plenty.
2) Level 2 cache locking issues. I've seen dozens of
threads waiting on a lock in the DataCache code. Not sure
if there's a deadlock happening here or just that the
threads are waiting on a lock that's being held for a long time.
3) Database Connection leaks or contention. I see threads
spinning in the DataSource code trying to get a connection.
I also see dozens of connections from the Postgres side which
seem to be sitting idle, but in the middle of a transaction.
When things get bad, I also see exceptions being thrown because
of timeouts waiting for a connection to become available. It's
a web app, PMs should not be tied up for more than a few seconds.
4) CPU usage pegged or nearly so for the JVM. I suspect
this is related to #3. Something very bad is going on here.
If I stop all inbound requests to the JVM when it's in this
bad state, it will continue to burn CPU at 90%+ for a very
long time. I think it will eventually finish what it's doing,
but I haven't had the luxury of waiting for it. It's definitely
not a linear slowdown proportional to the load.
Attached are my kodo.properties file and some thread stack
traces along with some comments. Any advice would be greatly
appreciated. This is not a complicated app nor am I doing
anything unusual. It doesn't seem logical that Kodo could
breakdown so dramatically under load, so I'm hoping it's some
sort of interaction thing that I can work around.
Thanks.

"Born with a broken heart" -Kenny Wayne ShepardPlease read prior posts regarding level 2 cache. It is unusable under stress
as far I am concerned. Basically entire cache gets locked on any database
read. Makes it very unscalable
Are you using 2.5.3? It will request a connection from a pool every time it
resolves reference to a PC even if it is cached in PM and therefore Kodo
does not need to read any. As result if you iterate over 100 objects in your
query and for each object resolve reference to another object (always the
same) kodo will request 100 database connections from the pool (and note
they issue rollback on every time they return a connection to the pool so
getting connection might be fairly expensive)
In conjunction with level 2 cache contention this causes application to go
into a stupor.
Try to go back to 2.5.2 (or may be 2.5.4 they promised in the near future
with a workaround) or use "persistent-manager" connection retention if you
discard PM after each HTTP invocation - it will take care of connection
pooling issue. As far as L2 cache I was unable to find any work around so
far - see if you might be better of without cache. You might if your object
graph is not very complex

"Born with a broken heart" -Kenny Wayne Shepard
With cahce enabled, 2.5.3
Here the app had recently slowed down and then effectively locked up.
There where many outstanding web requests that were not receiving output.
At this point most threads seemed to be waiting at the same location.
There were a large number of active database connections and most of
them had open transactions (according to pg_stat_activity). The app
was not responding to any web requests.
It would seem that db transactions had been started, then the thread
got stuck for a long time on a synchronization lock in the cache lookup.
Below are two randomly chosen thread stack dumps.

while running slow, 2.5.3
At this point, the app had been running several hours normally, then
apparently slowed down and locked up while I was away. When looking
at the app threads and database activity, everything appeared idle.
No transactions seemed to be open in the db. But the app was not
behaving normally. Web requests that did not make use of JDO worked
fine (but slow). But requests that hit the db either blocked or were
very slow to respond.
Looking back at the log, there had been a large number of requests
that threw exceptions because they could not get a connection within
five seconds.
Most threads were idle, waiting on read, but some were in the state
shown by the following two stack dumps. Unlike the cache threads above,
they did not seem to be waiting for a lock to be granted, they seemed
to be spinning in the connection management code. Apparently trying
to get a connection. I suspended and resumed the same thread repeatedly
and it always seemd to be doing the same thing. Single stepping was
very difficult because the debugger was slow to respond, apparently
because of other threads also busy spinning.
Postgres indicated that there where lots of connections open and
that they were all idle, so there should not have been a shortage
of connections in the pool. There are two mysteries here: 1) why
can't this thread get a connection? and 2) Why is it busy spinning?

With cache disabled 2.4.3
This run was an accident. I inadvertently ran the app with the older
2.4.3 version of Kodo, with the cache disabled. This one got into trouble
almost immediately. It also seemed to lockup with lots of opentransactions
in the db. It's also interesting that these two threads also seem to be
hanging around the same method as in 2.5.3.

I upgraded two machines to 10.5.6. Since then, both have experienced random hangs -- cursor switches to busy spin, keystrokes are ignored, and the only way to regain control is to power off.
The firewall was disabled recently to install our network backup tools. I enabled firewall on one
of the machines, a Mac Pro (two interfaces, but only en0 is being used) . It hung today at about 8:30 AM:

Network Manager shows "Ethernet 2" as Not Connected,
Status: cable is unplugged.
In the past, the port was used for "connection sharing", and there was a
cable plugged in with the other end disconnected, so it could be picking
up RF. I removed the interface from the NM list.Greetings,
You have something else wrong there, I updated my own 5 Macs, and 60 at the work site with no real troubles at all.
Dreamweaver works for me, as well as CS4, Suitcase, and many other heavy hitters. Mail, Safari, and all the standard apps that are part of Leopard, as well as iLife, and iWork, and Office 2008 all work fine.
I would uninstall DreamWeaver, and then re-install it. One person I know, not part of my group had similar issues as yours, and did just that, a re-install and it works fine now.
Like was stated in another post, there is some kind of corruption there. The update is not bad at all, in fact the only thing I noticed was, on one of my machines I have external speakers, and I get a loud pop at start up, but that will be fixed soon. That sort of thing is not that big an issue.
Good Luck - Happy Holidays.
Cheers,

Airport connection drops under load.
Hello Community!
I have some serious Airport connection woes - whenever I heavily use the airport connection it seems to drop out every now and then. The intervals have no visible pattern, but the dropouts are directly linked to the amount of traffic going trough the Airport card.
The dropping is quickly and the Airport connection icon goes from the full 5 bars to greyed out and back. This happens at an increasing rate when it has happend for the first time after an restart.
Here's a screencast I took to illustrate the problem: [www.verpeiltaber.net/airport.mov] (Quicktime, 1.30MB)
It also drops out (invisibly) when I Skype-Out, which is extremely annoying as I pay money for that and then the other side cannot hear me anymore after such a dropout. Strangely it never kills the entire call tough. It never happens when the computer is tethered to a LAN-Cable.
I have reinstalled Leopard from scratch just two weeks ago. I upgraded from Tiger before and had the problems with that version of the Leopard install aswell. Tiger didn't exhibit the problems - which leads me to believe that this is a software issue.
The Router is a D-Link 524 with the newest aviable firmware, and has been resetted multiple times. Other computers using the same WLAN work without any hitch.
This issue has popped up in my office WLAN, which uses a Lucent Router, aswell.
I'm pulling my hairs out here - help me please!
Edit: All the latest updates are installed, like the recent Time Machine & Airport update. No third party extensions or mods are installed. The issue is operating-system - wide.I have been having the same problem since upgrading to 10.5.2 and it's driving me nuts! Momentary disconnections every 10-15 minutes making messenger, iChat, etc. completely useless.
I purchased a 15" macbook pro for my partner 2 weeks ago - it's having the exact same issues. I'm thinking of returning the machine as I've tried everything. I have no problems with any other machine connected to my router. -
I have noticed a problem on FF4 when browsing sites that open pop-under windows on a user action. With all other browsers (including FF3) these open underneath the main window, but on Firefox 4 they open over the top - acting as pop-ups and not pop-unders.
While pop-unders are annoying, it is even more annoying to have them keep appearing as pop-ups instead.
I have run some tests and the following code successfully opens a pop-under on all browsers except Firefox 4.
It appears that window.focus() is not correctly bringing the current window to the top.
Example code:
var w = window.open('http://www.mydomain.com/', 'mywin', 'width=400,height=300,toolbar=1,menubar=1,resizable=1,scrollbars=1');
if(w){
w.blur();
window.focus();
}This is normal. Firefox 4 has disabled the default "window flip".
- go to adress about:config
- accept and search dom.disable_window_flip set to false;
And popunder, blur/focus javascript function will be back ;) -
My iphone 5 is not charging properly. Recently the USB cable was emitting sparks on connecting it to my laptop.This has resulted in physical damage of the wire. Is it still eligible for replacement since it is under 1 year warranty?
Why not. The iPhone was also delivered with a charger to connect to the wall outlet, use it

Hello,
Make sure your SQL Server service is started.
Make sure TCP\IP and names pipes protocol is enabled
Make sure you have made an exception in firewall for SQL Server connection
Make sure SQL Server browser service is enabled
Make sure you connect with correct name hostname\instance name for named instance,MSSQLSERVER for default instance and Hotname\SQLEXPRESS for express edition.
Please make sure you use port no when connecting to SQL server listeing on different port (hostname\instance ,portno)

Failover and Load Balancing with JNDI Connection Pools
Hi,
I am trying to figure out how would JNDI Connection Pooling work along with failover or DNS Load Balancing.
Would connections be distributed equally among the list?
Would the pool work with multiple heterogeneous connections (i.e. connections to different but equivalent servers ), or do all the connections in the pool have to be homogeneous (i.e. to the same server)?
Thanks,

SAPJ2EE Hangs at "Loading Cluster Manager"
We applied patch4 for EP 6.0 SP2, coming from 6.0.2.3.7 . The patch 4 install completed successfully as noted in sapinst_dev.log . When starting up the portal via the dispatchers go script, the portal hangs at "Loading Cluster Manager".
The TRACE.log file under .../cluster/dispatcher/managers/log/cluster continually erroring off with the following message:
2004-08-02 12:20:38 | ClusterManager | TRACE | unknown | unknown |
ID000473: Can't connect to localhost:50060.
a netstat -an does not show anything attempting to use port 50060, which should be the state controller.
Anyone seen an issue like this?
HPUX 11.11 - pa-risc
HP JDK 1.3.1.13
SAPJ2EE Engine 6.20 patch level 23Is the R/3 Start-up Framework service enabled? Often times this will conflict with the start-up when starting the portal using the go scripts.

30EA2 - connection hangs on initial connect.
I encountered this intermittently with 30EA1 as well. When I click on a connection to connect, I get a 'loading...' icon and the running progress bar is flashing away merrily, but the connection never opens. That is no object browser and no worksheet.
Looking at the database, there is a session open. The GUI is still responsive.
Nothing appears in the console.
Windows Vista SP2, JDK 6_11.

No shared spaces configured.I've already reported this one and got no response. Now with EA3 the product is unusable because it hangs EVERY TIME.
The sequence of events is
Start SQL Developer
Open a connectio
Loading... appears in the connection browser under the connection and the Running: progress bar flashes in the status bar... for ever.
The gui still responds and I can attempt to open other connections.
Any attempt to close SQL Developer gets the Connection Busy, retry abort message. I have to kill it from task manager.
Looking at the database there is a connection, but it is spending all its time waiting on SQL*Net message from client.

Extension Manager CS6 hangs on "Loading Extensions" and I cannot uninstall it.
Hello,
I've been having trouble with extension manager cs6 for about two days now, trying to apply patches to it to make it run more smoothly and stop hanging on "Loading Extensions". I have looked through these forums and they suggested that I remove all mxi files from a subfolder called "EM Store", but I cannot find a EM store under the proper location. I also cannot uninstall extension manager from my control panel, as it does not show up. I am just trying to get keyframe caddy for Adobe Flash, but I cannot get it without extension manager which is a giant pain. I've seen other people post both of their log files, but I think that just makes these forums impossible to find any real answers, as the majority of it is the log file. Please help asap, as I need this project that I am doing to be done fairly quickly.
Short story:
1. Manager hangs at "Loading Extensions"
2. Tried patching with updates, did not work
3. Tried finding the two subfolders, cannot find them at all in proper location
4. Cannot uninstall it from control panel
5. Need Help asapYou should delete EM Store and Database, then try again, you can find these folders under following path:
Current Machine's Extension Manager CS6 folder: C:\ProgramData\Adobe\Extension Manager CS6, under this path you should remove "EM Store", "Mxi Flag" and "Configuration" folder.
Current user's Extension Manager CS6 folder: C:\Users\<your_user_name>\AppData\Roaming\Adobe\Extension Manager CS6, under this path you should remove "EM Store", "Mxi Flag" and "Configuration" folder.
For the 'AppData' is a hidden folder, you could follow this guider (http://www.bleepingcomputer.com/tutorials/show-hidden-files-in-windows-7/) to unhidden it -
WL server failed to response under load
Hi
We have a quite strange situation on my sight. Under load our WL 10.3.2 server failed to response. We are using RestEasy with HttpClient version 3.1 to coordinate with web service deployed as WAR.
What we have is a calculation process that run on 4 containers based on 4 physical machines and each of them send request to WL during calculation.
Each run we see a messages from HttpClient like this:
[THREAD1] INFO I/O exception (org.apache.commons.httpclient.NoHttpResponseException) caught when processing request: The server OUR_SERVER_NAME failed to respond
[THREAD1] INFO Retrying request
The HttpClient make several requests until get necessary data.
I want to understand why WL can refuse connections. I read about WL thread pool that process http request and understand that WL allocate separate thread to process web request and the numbers of threads is not bounded in default configuration. Also our server is configured Maximum Open Sockets: -1 which means that the number of open sockets is unlimited.
From this thread I'd want to understand where the issue is? Is it on WL side or it's a problem of our business logic? Can you guys help to deeper investigate the situation.
What should I check more in order to understand that our WL server is configured to work with as much requests as we want?Thanks for a good explanation!
Linux server it's not in my competencies but what we have now is:
root soft nofile 3072
root hard nofile 65536
So the upper number is really big. As I understood it's a config for whole processes in operation system.
But I go further and find these numbers for our WL managed server.
cat /proc/23085/limits
Limit Soft Limit Hard Limit Units
Max cpu time unlimited unlimited seconds
Max file size unlimited unlimited bytes
Max data size unlimited unlimited bytes
Max stack size 10485760 unlimited bytes
Max core file size 0 unlimited bytes
Max resident set unlimited unlimited bytes
Max processes 578455 578455 processes
Max open files 8192 8192 files
Max locked memory 32768 32768 bytes
Max address space unlimited unlimited bytes
Max file locks unlimited unlimited locks
Max pending signals 578455 578455 signals
Max msgqueue size 819200 819200 bytes
Max nice priority 0 0
Max realtime priority 0 0
Again it's only a config numbers. If continue moving in this direction I'd want to see the real numbers when the server is under load. So finding these numbers I would make an assumption that the issue is here. Don't you know is there a log file or history file where I can find a max open file descriptors for WL server? -
[SOLVED] SSH, email - connection 'hangs'
Hello,
I have a problem with connections at work - it happens only at work, I tried on Arch and also Debian.
I haven't noticed it to affect 'web browsing' - it affects for sure ssh (incl. git) and sending email mesages.
What happens:
About 3/4 of times I try to send an email (google account from thunderbird), or log in to one of our servers with ssh (or pull/push some code from/to github) the connection 'hangs' and nothing happens. If I try ^C and 'redo' few times I finally manage to log in.
Log from ssh (unsuccessfull connection):
ssh bb5 -vvvv
OpenSSH_5.9p1, OpenSSL 1.0.0g 18 Jan 2012

My /etc/ssh/ssh_config on Arch is default (everything commented out)
~/.ssh/config has only few Host, User, entries
On Debian:
/etc/ssh/ssh_config
Host *
SendEnv LANG LC_*
HashKnownHosts yes
GSSAPIAuthentication yes
GSSAPIDelegateCredentials no
Trying to ssh to server's IP doesn't change anything.
Any ideas how could I track where lies the problem? Or maybe I could at least make it 'retry' automatically?
Edit:
After setting timeout in ssh_config I get
Connection timed out during banner exchange
at the end of unsuccessfull connection.

On Debian the openssl is 0.9.8g-15 and openssh is 5.1p1-5

I've set it already in ssh_config file (see my edit). Is there any way to make ssh 'retry' few times because now it gives up after first failure.
I've set ConnectionAttempts 5 but i'm not sure if it works - I'll have to give it another try on tuesday.
mr.MikyMaus wrote:Can it be that your employer does not like encrypted traffic in his network? I could imagine an IPS system trying to decipher the connection... Try moving the server-side ssl service to a non-standard port if you can...
It is possible - however I don't know exactly how is the network 'distributed'. Maybe I'll try to change it at least at one server and give it a try.
Anyway - what about emails for example - this uses port 25 (smtp on gmail) and is experiencing the same problems (message sending lasts until timeout 8 out of 10 times).
I don't know too much about networks - maybe there is some kind of service which doesn't work properly in my network at the office. Any clues what could it be?
Most important for me is to make 'git pull' work - because it's executed automatically on those Debian boxes and if it fails they are not updated.
So solution like 'make it retry 10 times per 5 seconds' will do the job for 90% cases I think. -
IPhone using Mac Mini's internet connection sharing, stops loading webpages
Bought an iPhone 1 hour ago.
I'm sharing my internet connection to my iBook and MacBook from my Mac Mini. Works fine.
Can't connect using the iPhone.
It will detect the network, it will show full network reception, but it will only load webpages for the first 10 seconds and then stops.
Tried removing the password, fixing a channel, resetting the iPhone (full reset), the "forget this network" trick, nothing worked.
It will load web pages in the first 10 seconds of detecting my open network. Its highly frustrating...
Any suggestions? Maybe using the restore option from iTunes instead of the reset ones from iPhone? Will this try to reinstall the latest firmware?Very similar case here -- I bought an iPhone just yesterday, set it up with internet sharing on my Mac Mini, and am getting random (but frequent) failures connecting via wifi. Small web pages can get through sometimes, large (or complex) web pages almost always hang during loading, e-mail pretty much never works.
However, using "edge" works just fine.
I've nosed around these forums a bit (and googled for this problem a bit), and it does seem like there are a number of users having this sort of trouble. However, some folks with this problem have noted that they can run wifi just fine at other hotspots. (I haven't taken my phone to another hotspot yet, maybe I'll try tomorrow...) And I've shared my internet connection to other PCs from my Mini successfully before. So, in my opinion, this problem does not appear to be an actual hardware fault in either the iPhone or the Mac Mini, but rather some disagreement between the settings chosen on both sides; my guess is that this'll take a driver modification in either or both to fix, rather than a replacement of either the iPhone or the Mini.
Just my current guess, though.

Battery level dropping under load while plugged in
Hi all,
I'm, the otherwise happy owner of a retina Macbook Pro form July 2014 (with a 85w power supply)
I have the issue that, whenever my computer is under load and uses the discrete graphics card, its dropping power - even though the charger was connected.I know the discrete graphics card uses up more power, but honestly it cannot be true that if I play a game in high settings on the macbook (which only has a keyboard, mouse and charger connected in that case), then the battery drops... It cannot sustain itself or what? (I have never experienced this with any other laptop, so I hope for the love of God, this is not what to expect).
Also, just the other day, I was using 2x external monitors (with their own power supplies), and just watching a Twitch (videogame stream) in a browserwindow on one of the screens, and the charge started dropping, even while plugged in again -- it dropped maybe (a wild guess) 10% an hour or so.
The setup there was: I had iMessage open on the screen on the macbook - nothing else; I had a PDF displayed on the first external screen and I had a browser-window open with a video-stream on the second external screen. A mouse, keyboard, powersupply and 2x videooutputs (1x HDMI, 1x DisplayPort), was connected to the macbook at that moment...
I mentioned that I couldnt play anything with high settings, or watch a videostream while using external monitors without draining the battery power to a friend that has had a few macs - he had note experienced it before, and told me to post in here (After we agreed that since the external displays had their own power supplies, they shouldn't be dealbreakers). I'm hoping you can help me shed some light on the issue and help me. If something might need to be sent back to Apple for replacement, I'd rather do it before I personalize it too much.
Thanks alot!Thanks for the answers I see.... A shame since the 85W charger is by my understanding the highest wattage one Oh well, thanks!
