Hi Owen,
Thank u for ur immediate reply on my doubt, but still my doubt not got clear.
If u look into the locked threads, the lock is happened in RMI layer. Concider following two threads:

Both the threads get locked in getting BufferedInputStread in RMI. If u can suggest some more hints that will very much helpful for me.
Thanks in advance,
Suresh Kumar

i grep'ed for my java process id, and did a kill -3 on it to get the thread dump:
ps -ef |grep Eatroot 3936 3845 68 16:12 pts/2 00:00:05 java EatCpu
root 3948 30293 0 16:12 pts/3 00:00:00 grep Eat
kill -3 3936
thread dump:

i read that "nid" in the thread dump is suppose to correspond to PID. when i give the -m option for the "ps" command (for all threads), i see:

but nid for all threads in the thead dump is the PID of my main process, 3936 (0xf60). is there a way to correlate the PIDs produced by "ps -efm" to the threads in the thread dump?
thanks!
-anniei upgraded to 1.5 version of java, and could see distinct "nids" in the thread dump after that..

Weblogic 8.1 sp4 on Slowwaris 2.7 - Thread dump included
Dear experts,
We have a time response problem within our production environment, following is our configuration :
Oracle 8.1.7.4
Weblogic 8.1 sp4
Solaris Sparc 2.7
JSP is pre-compiled, though the time response behaviour is rather weird, sometime quick and most of the time very slow, that we can not stand with ie. 5 minutes for displaying the mainpage, worse is client IE browser should be shut and restart. Below is the thread dump of our server, we will appreciate if someone can interpret it and possibly lead us to pointers how to solve our problem.

Help needed with diagnosis of WebLogic server thread dump
Sorry, my mistake - I was trying to search for "weblogic" before the dump file
loaded fully.... I am not very familiar with VisiBroker and may be totally
wrong, but my guess is it creates a thread for each connection/client. I would
look for VisiBroker properties or settings that could limit the runaway creation
of threads....

I am posting the thread dump obtained at the OutOfMemoryError stage. Anyhelp
in diagnosing the thread dump and possible fix for this error is highlyappreciated.
For information sake, while the web application encountersOutOfMemoryError the
example web apps and WebLogic console application work fine. So it looksto be
a case of memory outage only for my custom application.

Help with Thread dump analisys
We have problems with our application which runs on bea8.1 sp1.
Problem is that bea runs out from Threads (StuckThreads).
thread dums look same for all threads but i can's see what is wrong.

Can you post the full thread dump?
It looks like you have some code making an RMI call over the network.
Is it calling another server, or perhaps a loopback call into the same
server. The latter (opening a socket to your own process) is a good
way
to get a deadlock.

Thanks Rob,
sorry for delay but I was on vacation.
You are right about RMI, our app. consist from FE (front end) and BE (back end),
comunication between them is RMI.
We had some problems with BE but now we have new version and it looks ok.
Anyway thanks for help, if I will have again some problems then it will be

HELP!!! Why do my thread dump have so many locked monitor
In recent weeks, My customer's weblogic server become more busy.Each time I downloaded
the thread dump when CPU is busy than 90%,I found a lot of lock in the thread
dump! Especially the class named "weblogic.kernel.ExecuteThread" . It's the kernel
class of weblogic, Why were most of them locked?

In recent weeks, My customer's weblogic server become more busy.Each timeI downloaded
the thread dump when CPU is busy than 90%,I found a lot of lock in thethread
dump! Especially the class named "weblogic.kernel.ExecuteThread" . It'sthe kernel
class of weblogic, Why were most of them locked?

Large Memory Usage and Frozen [thread dump attached]
Hi,
SQL Developer (Version 2.1.1.64, WinXP Pro, Java 1.6, Oracle 10g R2) always uses at least 550MB of memory, if left open, for more than a day, it invariably goes up to 700-800MB.
If I close all windows and connections, virtually no memory is reclaimed.
I clicked + beside a view to see the columns, sqldeveloper froze for a few minutes, below is the thread dump.

Edited by: mdaly on May 21, 2010 11:42 AMThe cause of hang could be figured out from the thread dump.
I have fixed that in development code. It was happening from PL/SQL editor trying to create tooltip which locked up the connection.
I am not sure what would lead to memory bloat even if the tool is not in use. There could be memory leak from some component. I am investigating that.
Suggest you to keep ObjectViewers, reports & PL/SQL editor closed when not in use.
Have Sql Array Fetch Size preference to 50 if it's higher.
Do not have auto-refresh for Report editor.
Keep Sql History, Find Db Object, Snippets collapsed.
See if that helps.

Thread Dump issue with LD_ASSUME_KERNEL=2.4.1
Hi ,
When I take Thread Dump using 'jstack <PID>' in JDK 1.5 it givss me "sun.jvm.hotspot.debugger.DebuggerException" in the dump nothing more
I set LD_ASSUME_KERNEL=2.4.1 in my server to avaoid some other issue ( JVM crash some times)
Surprisingly, I can not stop my server ( my java process ) after that using our Shutdow scripts , Ctrl C or even "kill -9 <PID>",
I have to restart the machine or manually release uncleaned resources that my server occupied and restart the server
This happens Redhar 9 as well as in Linux ES.
Anybody faced similar problem?
Any help or information regarding this is highly apprecialted
Vasu

I've downloaded the glic-2.3.6 sources from gnu, so I could build it from those. I'm however reluctant to do this because I really don't want to break my install.
I do agree with you on the NPTL statement, but pvs relies on allegro, which relies on LinuxThreads. Allegro is not being ported to new versions of glibc, so that approach is unfortunately not viable.
@iphitus
I wasn't very specific - it's allegro as in a lisp environment.
I think I'll try and install an old version of arch on wmware instead. Is there anywhere you can check out glibc version numbering on old arch install isos (ie. do I need arch-0.[1-9].iso)? And anywhere you can download the old isos (tried filewatcher, but a lot of the older sites seem broken)?
Thanks for the replies,
Mads
PS. I noticed that you recommended slackware for old kernels in another thread. I'm however in a bit different situation as I need old versions of glibc. Furthermore I would prefer sticking to arch, but was wondering whether there were any specific reasons for not doing that. -
Hi, From my server log I noticed that there are some stuck threads. After looked at the thread dump thread 18 is blocking. MainPortalServlet.java is extends PortalServlet and line 96 is super.service(request,response); Please help me to analyse why it is blocking. Thanks.

at weblogic.kernel.ExecuteThread.run(ExecuteThread.java:183)Hi user9503787,
Can you please confirm if the Weblogic instance / java process you took the Thread Dump from was showing high CPU utilization?
Your Thread Dump data is quite interesting and a perfect example of a non Thread safe HashMap combined with a read/write race condition:
Thread #23 (hanging for 600 seconds+) is showing a potential infinite looping condition in at java.util.HashMap.getEntry(HashMap.java:361)
Thread #22 (hanging for 600 seconds+) is showing a potential infinite looping condition while performing a resize() following a put() operation
Weblogic Portal has some known issues which regards to usage of non Thread safe HashHap data structures; which under load can cause infinite looping and sharp surge of CPU (due to corruption of the internal HashMap index preventing exiting the internal loop); ultimately hanging the whole JVM.
We had the same issue for one of our Weblogic Portal 10.0 production environment and Oracle provided a patch (via Collections.synchronizedMap() ).
Please open a SR and Oracle, share these 2 Threads and discuss with the engineer about a patch / know issues regarding non Thread safe HashMap and infinite looping.
Regards,
P-H

Waiting for monitor enty messages in thread dump
Hi,
I've a thread dump of a container in a Oracle Application Server 9.0.4.1 (running 1.4.2_07) right before restart because off low memory and a lot of threads in this dump are in this state:
"AJPRequestHandler-ApplicationServerThread-1588" prio=1 tid=0x37634bf8 nid=0x1982 waiting for monitor entry [43f22000..43f2386c]
can anyone tell me what this means? Google didn't reveal anything useful.
Another thing I don't understand although it seems it doesn't do any harm:
"AJPRequestHandler-ApplicationServerThread-1630" prio=1 tid=0x09011a68 nid=0x1982 in Object.wait() [40276000..4027686c]

What is the monitor this thread is waiting for? According to the source in Inet4Address at line 287 the method tries to create a new byte array... is there some system monitor which can't be seen in the thread dump?
This thread holds a lock (0x663b2088) 46 other threads are waiting for...
Thanx in advance for any hints.

Collect Thread Dump using Script and direct to separate log file
Dear Legends,
I request you to provide me some useful guide lines to collect Thread Dump using script in linux and redirect the output to a separate log file, not the STDOUT file. If it is redirecting to STDOUT then how to extract only the thread stack to a separate log file.
i used
ps -ef | grep java
kill -3 <pid> >> ss1_td.log
but it is not providing the thread stack to the log file.
Anykind of help would be appreciated much.
Regards,
KarthikHi Ram,
Really a great and useful script for me at the right time. It solved my requirement and i made some changes to my requirement and the script it working fine to collect the thread dump and even i have checked the thread dump with SAMURAI works fine.
Helpful site also refer sites like these which contains more valuable things for weblogic. We will meet in the forums again.
Note: also please update several links available in the site like UNIX scripts, WLST, Python etc.
Regards,
Karthik -
The thread dump has a deadlock ?
We're experiencing a problem with the OC4J server hanging when some we unknow operation . I can see it's a connection pooling problem based on a thread dump. What I can't determine is why it doesn't release a resource in the first place. I've included some code to show where it is hung.

Sincerely from Ting-RungAbout the general situation describe like following, thanks you help.
Q1:Whether you could able to access the httpserver home page or any other application deployed in other OC4J container, when the server
become unresponsive.
Ans:Yes
Q2:What are the kind of applications deployed in the OC4J container ( hrmOC4J) .
Ans:The kind of applications is human resource application(Developer Tool is JDeveloper 9.0.5.2 and Jheadstart 9.0.5.19 and
oracle Application server 10.1.2.0.2)
Q3:Does server hang happen regularly or at what situation the server is becoming unresponsive ( high load, etc..)
Ans:No,It is not regularly when when server hang happen.
Q4:From the SR notes, the workaround you used is, restarting the OC4J container. ( what is the
kind of Oracle Application Server instance you have installed, please let me
know the complete version of the Oracle AS instance)
Ans:oracle Application server 10.1.2.0.2
Q5:Did you notice any out of memory issues when the server / particular OC4J container is hang

Program hangs, can't get thread dump
Hello
I have a Java program which sometimes works OK untill the very end, but sometimes just hangs in a random moment and doesn't react to Ctrl+C or Ctrl+Break. Process doesn't use CPU, so I guess it isn't something like infinite loop (I actually cannot think of places in my program where this kind of loop may occur). I tried to get thread dump to see if there are any deadlocks, but Ctrl+Break doesn't work and jstack doesn't work also (I've read that there is -F option, but it isn't available on Windows). Also I tried to connect to a process with Java Visual VM - doesn't help too (just says 'Connecting...' forever).
What else can I do to find out what's going on in my programm and fix it?
I tried to run it with JDK 1.6.0_07 and 1.6.0_16. I'm using Windows Vista Enterprise SP1, 64-bit.
Thanks in advance, Yulia.

Yesterday I tried to start my program, connect with Java Visual VM to it and see how threads visualisation will look like in a moment when program hangs. My programm died after about 50 min and all info which I was able to see was about this period of time (e.g. a timeline diagram stopped changing and the last time mark was 49:23), but Java Visual VM was still connected to a process. I tried to press Thread Dump button, it worked, but there was nothing 'criminal' on the dump it provided. So I guess maybe it's not actual thread dump, it's something that Java Visual VM was able to get before process hanged.
I don't have much experience in resolving this kind of problems, so any advices will be great appreciated.
