DGCServer - tried to renew lease for lost ref: 509

Recently we have been getting ALOTof messages in our server log file of the
form:
Fri Jul 14 10:08:19 PDT 2000: <DGCserver> tried to renew lease for lost
ref: 509
We use RMI for java client to server communcation and are using Weblogic
4.5.1 SP 8
with nativeIO enabled.
What could be causing these messages?
Thanks!
Rick

Thanks! I still have one problem, the lease renewal messages for lost
references never seem
to end for the specific reference. I have a weblogic.log file with hundreds
of those messages for
each lost reference (and still going). It seems that it is not giving
up... any ideas?

Normally, I would ask a customer in the situation to provide more about
their application. But, since I know a lot about how your application is
architected, I would guess the people are shutting down their browserswhile
your applet still running. The applet is not closing the socket cleanly
with Weblogic. The distributed garbage collector, which keeps track ofall
of the distributed objects, is trying to renew a lease for that object.It
cannot locate it and will eventually give up on it.

Tried to renew lease for lost reference

Hi
Oracle sessions get stuck on parsing all sessions accessing the same object wait
on "library cache pin".
We found one session coming from jdbc client waiting on "SQLNET message from client"
and holding all the rest sessions.
When we kill this session the problem resolves.
Following the port holding session with netstat, lsof and so on back to the jdbc
client side on different machine we only see error message connected to the same
port saying "tried to renew lease for lost reference". Our assumption is that
oracle lost connection with the client while locking a DB object when was doing
parsing and thus locked all sessions that wanted to access same object.
Did anybody encounter the same problem? How was resolved?
Thanks.

In testing the cluster failover capability, I disconnected the
network cable from one of the servers I was running in a cluster.
The system failed over properly. When I reattached the network
cable, the system added the server back into the cluster. However,
I continue to get the following message:
Tue Dec 12 17:34:51 GMT 2000: <DGCserver> tried to renew lease
for 1 lost references
(s).
What is the cause of this message? What needs to be done to clean
up the cluster?Rich,
This message is printed when one WebLogic kernel tries to renew a lease for
an remote object from another WebLogic which has already been collected. It
makes sense that this might happen in the failure scenario you describe.
When the network is disconnected DGC lease renewals can't be sent and the
kernel exporting the object may therefore believe that the object is no
longer in use and collect it. When the network is re-established the remote
objects may be gone.
However the fact that you are seeing this message printed repeatedly is
troubling. You may want to contact [email protected] with the
description you provided here along with the following additional
information.
Are you seeing this message on the client or server? If on the server is it
on the server that was disconnected or on one of the other servers? What
version (including service packs) of WebLogic are you running?

DGCserver messages in log... "Tried to renew lease on lost reference"

Hi,
 I am running weblogic server 6.1 and get the following messages
 ####<Jan 30, 2002 2:36:55 PM CST> <Info> <DGCserver> <MBarton> <myserver> <ExecuteThread: '12' for queue: 'default'> <> <> <000000> <Tried to renew lease on lost reference: '706'>
 I have seen in the newsgroup that this was a problem previously in version 4.5.1
 any help would be appreciated.

 This shouldn't cause any problems. Does it? We will turn off these info messages.

Tried to renew lease on lost reference

Hi all,
Can anyone pls help me with the following issue?
I have encountered the following message.
<ExecuteThread: '3' for queue: 'default'> <> <> <000000> <Tried to renew lease
on lost reference: '388'>
After a while, the following message will appear.
<ExecuteThread: '15' for queue: 'default'> <> <> <000000> <Unsolicited error response
for: '-1'>
This shows the threads in the server are all used up.
I will like to know the cause for the first message to appear and how to prevent
it. Whenever this message appears, it is telling us the server is going to hang
soon. We have no idea how to fix this problem. Can anyone help? Thanks.

I know the "tried to renew lease..." message you were getting was just some INFO
message that the server sent out. I believe this message has been surpressed
in Weblogic 6.1 SP3.
Not sure if the other message is part of that. I've been running with the service
pack for so long that I don't remember. :)

Tried to renew lease on lost reference in logs.

 I am using Weblogic 6.1 SP1 with 2 cluster configuration. I am seeing a lot of
 "Tried to renew lease on lost reference" msgs in my logs. These msgs seems to
 be logged almost every minute.
 I would like to know what does this msg mean and how would I elimiate this msg
 from my logs.
 Any help will be appreciated.
 Thanks
 Albert


I am relatively sure it has to do with RMI and distributed "garbage
 collection", so it may be related to some of your replicated JNDI entries.
 The other question is what is causing the problem in the first place. Are
 your servers under intense load or are the exec threads getting saturated
 (whether or not the other resources like CPU are saturated)?
 As far as the low-level RMI implementation, I know that Weblogic has its own
 implementation for significant portions of RMI, but I don't know much about
 the implementation, so it is hard to guess. You may be able to get some
 additional pointers from Prasad Peddada[[email protected]].

DGCServer messages in log... "tried to renew lease"

Hi,
 I'm running three WL 4.5.2 servers clustered, JDK1.1.7b on Solaris 2.6.
 Normally the cluster runs just fine, but now I'm beginning to see the
 following message in all three servers:
 <DGCserver> tried to renew lease for lost ref: nnn
 Usually they come in small bursts of about 5 or 10 messages that are the
 same, except the "ref"s keep increasing. I'm guessing it has to do something
 with the in-memory replication of sessions (which I'm using).
 Any ideas? I tried restarting the servers but after a little while the
 messages started again.
 Thanks,
 Matias


One common symptom for this (Bad Status Exception) has been long gc. If gc
 takes more 30 seconds then you will start seeing these errors. To assertain
 this, you could turn on weblogic.debug.cluster=1 and if you see a message "Timed
 out server" in the log then you should tune your server.
 Please use latest service packs.
 thanks

Renewing lease for wifi problem

When using my iPad on wifi, I need to continually manually renew lease in network settings to stay online. Why?

Open up the control panel in your router, from the pad, or from a pc. There is likely a setting buried in there focused on lease time, or when a lease needs to be renewed. Change it. If you do not know how to get control of your router, google your routers name and control, or access address. It is a web type, or ip addrss that will take you to the router control page. You will likely need to log in, and usually the log in is guest with no password. If you have previously looged in and changed those defaults, use what you changed it to.

Apps continue to Renew Subscription for lost iPad

I had an iPad stolen about two months ago. I had the Popular Science Application on there with an automatic renewal for hte subscription, so every new magazine would automatially download onto my ipad. How do i stop this from happening anymore? I dont want to keep paying for a thief to get new Popular Science Magazines.

There are instructions on this page for managing and stopping auto-renewing subscriptions : http://support.apple.com/kb/HT4098

DGCserver renewing lost refs

Hey all,
We're running WLS 4.5.1sp5 on solaris 2.7.
After some time, we start to see our execute queue length start to
increase dramatically. At the same time we start to see the following
messages:
Fri Jul 06 12:03:54 EDT 2001: <DGCserver> tried to renew lease for
lost ref: 677
Fri Jul 06 12:03:54 EDT 2001: <DGCserver> tried to renew lease for
lost ref: 678
Fri Jul 06 12:03:54 EDT 2001: <DGCserver> tried to renew lease for
lost ref: 692
This happens a lot and soon after start up on the new hosting
environment but hardly ever on the old hosting environment and never on
the development machines. The boxes are all the same... why would this
happen?
Any insights would be appreciated.
C.

Chad,
These messages indicate that a server got a message to renew a DGC lease for
a reference it had already collected. This means that the lease renewal
messages aren't being received and/or processed in a timely manner. Since
you mention that the execute queue length is quite long that is likely the
cause of the problem.
To diagnose that problem I would recommend taking a thread dump from the
server VM. Look at what the threads are doing. Are they blocked trying to
obtain some resource or doing some other operation that is preventing them
from proceeding?
Cheers!

Renewed lease messages in cluster log

I just started a cluster of 2 servers, and so far it seems to be working
 ok. I'm alarmed, however, that the log file is being saturated with
 entries that look like this:
 Fri Oct 29 09:02:19 CDT 1999: <DGCClient> Renewed lease for 19
 objects hosted by
 2789039048855955648Sxxx.xxx.xxx.xxx:[2114,2114,2124,2124,-1]
 Note: xxx.xxx.xxx.xxx is the host name of the other server in the
 cluster, 2114 is the listen port and 2124 is the SSL listen port.
 A new line gets added every minute about a renewed lease. Is there any
 way to turn this logging off?
 Thanks.

Self-assigned IP after trying to renew DHCP lease for former network

Hi all,
MacBook Pro 15" purchased in Februrary 2008, currently running 10.5.5, up-to-date with patches as of yesterday, 10/20/2008.
For a few weeks now, I've been consistently unable to connect to wireless networks (secured or unsecured, public or private) after changing networks (i.e. going from home to a coffee shop).
I have control over my home network router, and its logs show that upon connecting to the network, OS X tries to renew a DHCP lease for the previous network it was on. Upon receiving the "bad network" DHCP reply, instead of releasing the lease and obtaining a new one, the AirPort interface is immediately assigned an IPV4LL address (from 169.254.0.0/16) and no combination of changing network settings, changing AirPort settings, or rebooting will eliminate the old DHCP lease.
The end result is that my MBP is entirely nonfunctional on some wireless networks that other clients (both Windows and Mac) seem to have no trouble accessing. The problem is quite annoying because I can't connect to access points that (previously) worked fine and whose configurations haven't changed.
In any case where this problem occurs, an old DHCP lease for a different network (10.0.0.0/8 when trying to get on 192.168.0.0/24 or vice versa) is present, so I strongly suspect a DHCP problem. In all cases, I have perfect connectivity to the access point itself, so problems with the wireless connection parameters (including encryption), or those troublesome problems with 802.11b/g/n interoperation seem highly unlikely.
One of two things would help me:
1) Please tell me how to clear the DHCP lease cache. Deleting files from /var/db/dhcpclient/leases does nothing (they appear again upon reboot, identical save for timestamps even after changing network environments, so the cache must be read at boot time and written at shutdown). Selecting "Renew DHCP lease" from the "TCP/IP" tab in the advanced network settings merely attempts to renew the existing lease (for an invalid IP address); it does not appear to release invalid leases.
2) If this is really how the DHCP client is behaving, change the DHCP client so that upon receiving the "Bad network" response, it releases (or simply abandons) the lease and obtains a new one, rather than immediately assigning an IPV4LL address to the AirPort interface.
Additionally, is there any documentation on the Apple DHCP client? Under Linux, I could alter dhcpcd parameters to diagnose things like this. I could find no documentation about the Apple DHCP client outside of Mac Help, which wasn't really any help in this case.
Finally, I do not suspect that this is an instance of the problem discussed in http://discussions.apple.com/thread.jspa?threadID=1352518&tstart=0 as my connection is rock-solid if it can get an IP address when it connects. I've never even seen it hiccup.
Thanks,
Matt Z.

I have had wireless problems intermittently for a year, and seriously for 6 weeks. Apple denied the issue and was no help in spite of many tens of thousands of people on their own discussions complaining. I found a post suggesting a couple of things which fixed the problem. I don't know if both are necessary, but the first by itself does not solve the problem.
Lock the channel of your router to channel 1, apparently Apple and 802.11n don't play well together on higher channels. When this becomes a standard this will be resolved I hope.
Open your network preferences, select 'airport' and advanced. Delete unused networks. Select your network.
Open TCP/IP and write down all the settings, configure iPv4 manually. Enter the settings manually. Turn off IpV6.
Open DNS and write down your DNS server. Delete it and re-enter it manually.
This has worked on 2 macbooks and an iMac for the last 3 weeks with no network drops.

Why does my ipad not have a renew lease button or a forget network button? it's a first generation i think

Honestly, I'm at my wits end I've been trying EVERYTHING to get a wifi connection: I reset my network settings TWICE and reset my router and checked to see if my password was put in properly. This issue happened after my charger for my Ipad broke and I had to leave it dead for at the LEAST six months. During this time we lost our old network connection because it became unsecure and now anyone can use it so we got a new connection and it requires a password I have the password and evertime i put it in it refuses to work! Mind you my ipad never had an issue connecting to our old network that required a password (well used to). Ever since i charged it again for the first time in a long time it has only connected to the old network that is pretty much dormant and is a complete waste of time since it doesn't work right and now whats making me frustrated is that it won't connect to the old one either after i reset my network and it DOESN'T even need a password! like I really want to cry....I really need help with this.

It doesnt have renew lease or forget network button either.

This should get your itunes store connection working.
Close your iTunes,
Go to command Prompt -
(Win 7/Vista) - START/ALL PROGRAMS/ACCESSORIES, right mouse click "Command Prompt", choose "Run as Administrator".
(Win XP SP2 & above) - START/ALL PROGRAMS/ACCESSORIES/Command Prompt
In the "Command Prompt" screen, type in
netsh winsock reset
Hit "ENTER" key
Restart your computer.
If you do get a prompt after restart windows to remap LSP, just click NO.
Now launch your iTunes and see if it is working now.
If you are still having these type of problems after trying the winsock reset, refer to this article to identify which software in your system is inserting LSP:

Wi-Fi Renew Lease Not Working

The Wi-Fi connection for my 3Gs on my Airport Extreme home network occasionally quits working, but by doing a Renew Lease under network settings on the phone I 'was' able to get it working again it right away. But now for some reason that no longer works. Any suggestions?
I tried Forget this Network and reconnecting, but that didn't do it.

Well I called Apple and they were absolutely no help. They said the problem was likely with my Airport and not the phone, so I'd have to pay for support. I think that's bogus

How do i solve the problem with repeated renew lease requests

How can i solve the problem of repeated renew lease requests?

Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased. http://support.apple.com/kb/ht1430http://support.apple.com/kb/ht1430
You don't say what you are doing or trying to do. See #5 below.
Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netwhttp://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are drooping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Note - When troubleshooting wifi connection problems, don't hold your iPad by hand. There have been a few reports that holding the iPad by hand, seems to attenuate the wifi signal.
Some Wi-Fi losses may stem from a problematic interaction between Wi-Fi and cellular data connections. Numerous users have found that turning off Cellular Data in Settings gets their Wi-Fi working again.
You may have many apps open which can possibly cause the slowdown and possibly the loss of wifi. In iOS 4-6 double tap your Home button & at the bottom of the screen you will see the icons of all open apps. Close those you are not using by pressing on an icon until all icons wiggle - then tap the minus sign. For iOS 7 users, there’s an easy way to see which apps are open in order to close them. By double-tapping the home button on your iPhone or iPad, the new multitasking feature in iOS 7 shows full page previews of all your open apps. Simply scroll horizontally to see all your apps, and close the apps with a simple flick towards the top of the screen.
Wi-Fi or Bluetooth settings grayed out or dim
