BGP stuck in opensent state

HELP! Been looking at this problem all day. Have a simple BGP config on my end (below). I have no control on the other end. Recently upgraded from 2811 to 2911. IOS: c2900-universalk9-mz.SPA.151-4.M7.bin Configs on old and new routers exactly the same.
Called our ISP. They see the same debug logs, but have no clue to fix. I can ping across fine. No MTU issues. Move connections back to old 2811 BGP comes up no problem.

I'm also seeing that SAFI 8 is multicast:

If this is the case, the settings that you have above simply wouldn't work. I would contact the ISP to see what your peer is running.

Workflow stuck in starting state after applying SharePoint 2010 CU December 2012

I have custom visual studio workflow which are associated with Custom content type. workflow gets triggered automatically when a file is uploaded to SharePoint. Everything was working fine till when i apply the following CU
http://blogs.msdn.com/b/joerg_sinemus/archive/2012/12/27/sharepoint-2010-and-december-2012-cu.aspx
After applying this my workflow get stuck in "Starting" state.
No error were logged in 14 hive logs.
Thanks in Advance!

It took me a while but I came up with a work around. There is a PowerShell script below that can be used to trigger the workflow. Hopefully this will hold all of us over until the official fix arrives.
First remove the auto start on change or new from the affected workflow
Edit the script below to match your environment
Add the script to Windows task scheduler with the PowerShell.exe in the command line
This assumes PowerShell.exe is in the path
Then add the full path and script name in the add arguements text box
Script:
#The purpose of this script is to start the SPD workflow with the windows task scheduler for a trigger
#This should avoid the check in-out issue caused by the December 2012 SP CU patch
#This needs to be run on an account with membership in the farm administration group for SharePoint and Shell in SQL
#You can use a find and replace to replace the server and other names with your actual names
#There are no status messages being used since this will be a scheduled task in the Windows task scheduler
#Add SharePoint modules and create variable space
add-pssnapin microsoft.sharepoint.powershell
start-spassignment -global
#Open the web site, list and the workflow

Agent get stucked in Reserved State

HI CUCCE gurus,
Need assistance on this issue. In our remote office, our Sales Team has a linegroup setup, the Sales extensions are part of the linegroup and at the same time its their ACD line when they logged in to Cisco Agent Desktop.
The issue is, when they got a call from the linegroup their CAD state change to "Reserved" and it stuck from that state and nothing they can do to change the state but to logoff, close the apps and log back in.
I enabled debug on once of the Sales CAD (see attached output).
Any troubleshooting tips that you can advise or detailed steps to check from our system.
Our CAD is 7.X
Our CUCCE is 7.X
Our CUCM 7.X
Thank you.

Hi Jhun,
Agent stuck in reserved state it means, the ICM has reserved the agent, but the call is not getting delivered to the agent extension.
If you are using SIP trunk, you would probably need to check the CSS and Partitions over the trunk. Also, any recent changes made on the CSS of the SIP trunk you would need to reset the SIP trunk.
The CSS on the SIP trunk should contain the partition of the phone.
Also, you would need to check on the Agent targetting rule in the config manager of the ICM. The agent extensions should be added to the Agent targetting rule
Hope this helps!!!
Cheers,
Dass

I have a set of 3 USB disk connected to my TC via a USB hud. I usually swithc the TC at night. When I restart the next day it stucks in amber state. when I disconnect the USB hub where my discs connects and restart, it start properly. Any hints?

I have a set of 3 USB disks connected to my Time capsule (TC) via a USB hub. I usually switch the TC at night. When I restart the next day it stucks in amber state. When I disconnect the USB hub where my discs connects and restart, the TC will start properly. Any hints?

LOL.. don't switch off the TC.. this is fairly typical behaviour..
Or try a different usb hub.. but you could well and truly run out of hubs before you fix the problem.
Are you running latest firmware for your TC?
What error message is coming up in the airport utility.. amber led is a fault indicator.. look up what the actual fault is and see if it is for instance overloading the usb. You are using a powered hub??
Get one bigger USB hard disk instead of 3 smaller ones.

Content Switching Module (CSM): Sessions stuck in closing state

Hi guys,
I'm troubleshooting a CSM with 4.3(1).
We migrated a real server from windows to linux, since then lot's of sessions stuck in closing state until the idle timer expires.
I traced the traffic from the client to the csm and from the csm to the real server what I saw is the following behaviour at the end of a session:
windows real server: client sends FIN -> real server acks the FIN -> real server sends FIN -> client sends RST -> real server sends RST -> CSM deletes session from session table
The linux real server mostly behaves like the windows real server but sometimes behaves as follows:
client sends FIN -> real server sends FIN, but does not ack the FIN sequence number of the client -> real server sends RST -> client sends RST -> CSM does not delete session from session table, it stucks in closing state
Does anybody know how I can solve this problem of half-closed sessions other than decreasing the idle timeout?
Is it possible to configure CSM to close and delete sessions not only on FIN-ACK packets but also on RST packets?
Or to use a different fast idle timeout when sessions are half-closed?
Many thanks in advance,
Thorsten

Hi Fabrizio,
CSM_FAST_FIN_TIMEOUT is already set to 10 seconds.
What I found out while testing is that CSM_FAST_FIN_TIMEOUT works with configurations where idle timeout is configured > 0.
But when idle timeout is configured to 0 (what meas no idle timeout) the csm seems not to use CSM_FAST_FIN_TIMEOUT: Half closed sessions will stuck in closing state.
Any idea why cms behaves this way?
Regards,
Thorsten

Hi Milo,
Please check whether you have installed any CUs for SharePoint 2010.
Please install June 2013 CU or higher for SharePoint 2010, compare the result.

[SOLVED] Mailbox import requests stuck in 'queued' state

We have a small Exchange 2013 environment with one server having all roles. I try to import archive mailboxes from an Exchange 2010 environment. It has worked quite well for a while. However, all import requests are now 'stuck' in 'queued' state. Restart
of Replication service, transport service and even server reboot didn't help.
When I run
get-mailboximportrequest | Get-MailboxImportRequestStatistics -Includereport | fl
I observe that PositionInQueue value tells me that there are 85 import requests waiting :
ItemsTransferred                       :
PercentComplete                        : 0
CompletedRequestAgeLimit               : 30.00:00:00
PositionInQueue                        : 85/90 (Position/Queue Length)
InternalFlags                          : None
FailureCode                            :
There should be no requests waiting as I removed all requests in advance before I issued new import requests:
get-mailboximportrequest | Remove-MailboxImportRequest
How can I really reset an import queue by zeroing PositionInQueue ?
Any suggestions/tips?

Ciscoworks daemon manager stuck at Stopping state

I am working on LMS 3.2 . Tried to stop the daemon service with " net stop crmdmgtd ". It stuck on stopping state since few hours now. I can still open the application. Need a suggestion to terminate the previous command and restart the
daemon service.

You should have dmgtd.exe process in Task Manager stuck.
Although you can kill it directly and then try the stop command once again before starting. But to be sure if any process in not stuck, best way would be to reboot the server once.

VM got stuck in "stopping" state, and cannot be stopped

Dear all,
I am using Oracle VM 3.2.2.
One of my VM got stuck in "stopping" state, and cannot be stopped.
How can I troubleshoot this problem...

Q: Is the VM still running, i.e. can you ssh to the VM?
Q: Find the server where the VM is running, and restart the ovs-agent, i.e. "service ovs-agent restart". Did this help, or is the agent crashed, any zombies?
Possible root cause: These type of errors are typically ovs-agent bugs. First update oracle vm manager to the 3.2.4 release, not 3.2.6. Next update the dom0s to 3.2.4, not 3.2.6. You may need to setup a ULN 3.2.4 yum repo to update the dom0s. As you can see in these forms, 3.2.6 is may not ready for prime time, stick with 3.2.4, is stable.

Azure Cloud Service Stuck in "Stopping" state for a long time (12 hours)

Does anyone have suggestions what to do with the issue I have. I tried to stop my Cloud Service the service is now basically stuck in "Stopping" State and been there over 12 hours. In my Cloud service there is 16 Virtual Machines I am using in
testing.
I tried to start Cloud Service but it also failed with error "Could not start the virtual machine deployment.".
Is there something I could do or some way to get Microsoft Support (without paying extra)? I have "Visual Studio Premium with MSDN" so i have no other support but billing from Microsoft :(

Managed to find the solution. I stopped and deallocated all the Virtual Machines. After that the Cloud Service status changed to stopped state. After that it was possible to start the Cloud Service again.

Hi Bowen,
I've checked the local agent has been offline at 2014/09/05 18:00:00 UTC+8, as the shop close every night and they will shut down the computer, but they've turned on the computer in next day morning, and they keep turning that off at night, turn
back on at next morning.
I've checked the agent was online during that "stuck" period when the computer was turned on, as I could click the "PING SYNC SERVICE" and it reported it could reach the sync server, and I could also view from the portal that the agent
was online, just the sync group stuck in the "processing" status.

As the client need the sync to be fixed ASAP, cannot wait for the answer / help, I've removed the sync agent, compare the data (what data need to download from Azure to client, what data need to upload from client to Azure) and recreate back the sync group.
Hi Micheal,
Is this the workaround in your scenario? Since the Azure SQL Data Sync failed, the Microsoft support engineer will help to solve the problem from backend based on your subscription ID and Sync Group ID. Sometime delay might be expected. Your patience is
greatly appreciated. Thank you for your understanding and support.

hi can anyone help me?
my 5s is stuck in recovery state. Now its gone off it seems and doesnt come on. It's dead.

You need to upgrade your computer's OS to at least OS X 10.5.8 and use iTunes 10.5.
With OS X 10.4.11, you cannot upgrade beyond iTunes 9.2.1.
OS X upgrades from 10.4.XX to 10.5.XX require purchasing a DVD with the new OS. If your laptop has an intel processor, you can upgrade directly to OS X 10.6 for $29.
Take your laptop to the store with your new phone and ask them what your best options are.
