Jstack shows a thread waiting for monitor entry but it's already acquired

I have a heavy load website powered by tomcat-6.0.14 and jdk1.6.0_02-b05(amd64) on a 2 dual-core amd Opteron. When tomcat started, and I directed the http request(~200/s) abruptly to tomcat, it looks choked for over one minute, and if I took off the http requests, tomcat can recover in a few minutes.
Then I use jstack during the choke time to find what's the cause, where I found a strange situation. Almost all threads are blocking on getting a log4j lock(I think it's normal,since log4j use a coarse lock), but one thread which already got the lock are also blocked. Below is the stack trace.

I'm really wondering why jstack shows the first thread is BLOCKED but no blocker.
And also, it's not a deadlock, since I made jstack log after sever seconds, and found this time another thread has the same problem.

What's the cause? Is jstack accurate? Or, the problem is caused by hotspot compling since tomcat is just started? Or it's just because log4j's coarse lock? ( but after the starup, tomcat can handle the same traffic without any problem, and jstack shows no log4j block at all.)
Thanks in advance.

It seems like a Dead Lock.
The thread must have entered into a synchronized block/method1() and acquired a lock.
- locked <0x00002aaab39d5670> (a org.apache.log4j.spi.RootLogger)
While having lock the thread might be trying to acquire a lock to another synchronized block/method2()
waiting for monitor entry
java.lang.Thread.State: BLOCKED (on object monitor)
and someother thread might have already acquired a lock to that block/method2().
Can we check for Dead Lock??

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:

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.

Hello, I have songs that show they are "Waiting" for download from the cloud but they are greyed out. Some songs in one album are done others in the same album will not download. It is not a time function because i have been working on this for weeks. I have allowed my compter to run for days and the songs are still not accessible. I have a Match subscription and Match is working. If I click on the "Genre" link the greyed out songs show that they are ready for download from the cloud but I cannot download them. I have downloaded over 1500 other songs, so I am trying to understand what is going on here. I would appreciate any help anyone can give me.
Thanks

I did think about that and if I have to I will do that, however there are about 50 songs. I have closed and reopened iTunes several times and I am sure that I have the latest version. It fails right away but I can click on the cloud download icon and download the song that it failed on ... therefore it is not that song "or any one song" causing the issue. Any ideas?

Hi Kirby grace bete,
Thanks for visiting Apple Support Communities.
If you have not received the verification email for your Apple ID, I recommend visiting the My Apple ID page to make sure your email was entered correctly, and re-send the verification email.
You can also resend the email verification if the email address is not verified:
Sign in to My Apple ID to manage your account information.
Click Resend under Primary Email Address.
Verify your changes by following the link in the email you receive from Apple, then signing back in to your account.

You're gonna have to restore the iPhone from your last backup with iTunes. You did do a backup before you attempted to update the software didn't you?

App Server Freeze - All threads waiting for replication data

          We are running Weblogic 6.1 SP2, on solaris 8 with jdk1.3 When running load at our
          application - full GC is taking between 15 -20 seconds. At a certain point after
          a full GC on one of the servers in the cluster we see session replication errors
          in the logs. The application eventually freezes - the execute queue is huge on each
          of the JVMS and when we do a thread dump we see that all threads are waiting for
          replication data. All threads have the same stack trace as follows:
          "ExecuteThread: '1' for queue: 'default'" daemon prio=5 tid=0x2c58b0 nid=0xe waiting

TS4062 ipad frozen, tried reset from rec. mode, usb cable showing on screen, waiting for ipad, then ipad fails to respond. what can i do?

ipad mini froze when charging, have tried all restore options, when i get to waiting for ipad in itunes when restoring in recovery mode the usb cable disappears from the screen, the apple logo appears then the recovery line beneath logo, then there is no further response from ipad. have been trying to resolve this issue for couple days now very frustrated. can anyone help please?

Use the charger that came with the iPad or a name brand charger of equal or greater capacity. Plug that into a known good wall outlet. Then wait at least an hour. While the iPad is still plugged in to the charger reset your iPad. Press and hold the Home and Sleep buttons simultaneously until the Apple logo appears. Let go of the buttons and let the device restart.
If the iPad restarts continue to charge it until the battery is at 100%
If the iPad does not start Make an appointment at an Apple Store to have your device examined by a technician. Or contact Apple Support.

HT1212 My Ipad has been permanently lock because incorrect password has been enter too many times. Normally, it will ask to wait for 60 minutes but this is not available, the only option, it says to connect to Itunes. I cannot connect to ITunes either.

What can I do to unlock the IPAD if I cannot access the device by using computer? When I connect to computer, it says I have to unlock the IPad to connect to itunes.
I try everything but I cannot figure out what to do. I turn off IPAD and it still stay in the connect to Itunes mode. It does not goes back to wait mode.
Any suggestion would be appreciated.
Thanks,
Bill

‘iPad is disabled’ fix without resetting using iTunes
Today I met my match with an iPad that had a passcode entered too many times, resulting in it displaying the message ‘iPad is disabled – Connect to iTunes’. This was a student iPad and since they use Notability for most of their work there was a chance that her files were not all backed up to the cloud. I really wanted to just re-activate the iPad instead of totally resetting it back to our default image.
I reached out to my PLN on Twitter and had some help from a few people through retweets and a couple of clarification tweets. I love that so many are willing to help out so quickly. Through this I also learned that I look like Lt. Riker from Star Trek (thanks @FillineMachine).
Through some trial and error (and a little sheer luck), I was able to reactivate the iPad without loosing any data. Note, this will only work on the computer it last synced with. Here’s how:
1. Configurator is useless in reactivating a locked iPad. You will only be able to completely reformat the iPad using Configurator. If that’s ok with you, go for it – otherwise don’t waste your time trying to figure it out.
2. Open iTunes with the iPad disconnected.
3. Connect the iPad to the computer and wait for it to show up in the devices section in iTunes.
4. Click on the iPad name when it appears and you will be given the option to restore a backup or setup as a new iPad (since it is locked).
5. Click ‘Setup as new iPad’ and then click restore.
6. The iPad will start backing up before it does the full restore and sync. CANCEL THE BACKUP IMMEDIATELY. You do this by clicking the small x in the status window in iTunes.
7. When the backup cancels, it immediately starts syncing – cancel this as well using the same small x in the iTunes status window.
8. The first stage in the restore process unlocks the iPad, you are basically just cancelling out the restore process as soon as it reactivates the iPad.
If done correctly, you will experience no data loss and the result will be a reactivated iPad. I have now tried this with about 5 iPads that were locked identically by students and each time it worked like a charm.
~~~~~~~~~~~~~
Try it and good luck. You have nothing more to lose if it doesn't work for you.
 Cheers, Tom
