2012 Client stuck problem

Question

Hello. I've come across an oddity and I'm a bit stuck. I was reviewing some application deployments and noted that in one particular room, after a month half of the PCs were still reporting an "In Progress" state. I remoted on to one of these PCs
and found that there was about a dozen apps waiting to install. Two were listed as "downloading", the rest were waiting.
I had a flick through the logs and found that the CAS log was filling every 5-9seconds with the same line:
<![LOG[IsCacheCopyNeeded returned 'true' by {5777363A-FB22-4a42-ABB0-522DD42711DC}]LOG]!><time="10:29:04.624+00" date="11-27-2013" component="ContentAccess" context="" type="1" thread="260"
file="cachemanager.cpp:344">
...it's the same reference on every PC stuck in this "in progress" state.
I have also noted the CCMEXEC log is spamming the following line every ten minutes:
<![LOG[No logged on cached user during monitor task, trying to select.]LOG]!><time="20:20:57.378+00" date="11-21-2013" component="CcmExec" context="" type="1" thread="1660" file="senslog.cpp:1570">
...even if someone *is* logged on.
I have noticed this in the LocationServices log:
<![LOG[The number of discovered DPs(including Branch DP and Multicast) is 0]LOG]!><time="14:32:37.783+00" date="11-21-2013" component="LocationServices" context="" type="1" thread="1672"
file="lsutils.cpp:872">
Also, the SMS service will not stop cleanly. It hangs when attempting to stop.
What I've tried:
Attempting a client repair doesn't work.
Purging the download catalogue/Software Distribution/Catroot2 folder doesn't work.
I have tried uninstalling the client, purging the above folders and then reinstalling. The CAS is now behaving but the machine seems dead in the water in terms of the missing osftware updates, AppV 4.6 apps, AppV 5 apps and the physical installs.
I don't really want to ask that half a teaching space is taken out for a rebuild, do does anyone have any ideas? I am at a loss to understand why twenty PCs out of eight thousand have just suddenly all started showing the exact same error in the same room.
My gut is pointing at the network or boundaries?
Cheers.

Rashmika, do you remember the log file that ultimately told you about the faulty app? We *are* using App-V and I'm seeing this problem on a number of machines.
Hi there, sorry for the delay, but I had to dig through two eyars of email archive to find the info xD
In order to track this down, I enabled logging on the client by doing the following:
1. Open regedit and navigate to following location
HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ CCM \ Logging \ @ GLOBAL
Set LogLevel to 0
1.    Create the following KEY under HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ CCM \ Logging\DebugLogging Name: Enabled DataType: REG_SZ Value : True
...and then CAS.log started showing more information about the issue. Originally it was just spamming:
<![LOG[IsCacheCopyNeeded returned 'true' by {5777363A-FB22-4a42-ABB0-522DD42711DC}]LOG]
However with the above keys set, I could now see:
<![LOG[IsCacheCopyNeeded returned 'true' by {5777363A-FB22-4a42-ABB0-522DD42711DC}]LOG]!>
<![LOG[Found the AppV package [{B866BAFB-8F26-4C87-9169-3B6269EED5A1}] uses ConfigMgr content ID [Content_74376190-0a4e-4c73-a4d0-955b1bb76961] version 1, and it is configured as download and execute]LOG]!>
<![LOG[The AppV package {B866BAFB-8F26-4C87-9169-3B6269EED5A1} is not fully loaded into AppV cache, so we cannot delete the ConfigMgr cache copy(content ID Content_74376190-0a4e-4c73-a4d0-955b1bb76961 Version 1)]LOG]!>
<![LOG[The content Content_74376190-0a4e-4c73-a4d0-955b1bb76961 version 1 is needed]LOG]!>
...so now I had something concrete, and perhaps a reasonable explanation towards what was happening. If I recall, it wasn't so much package/reference 5777363A-FB22-4a42-ABB0-522DD42711DC, this was a bit misleading. I now had the actual content ID and a package
reference that led somewhere!
Hope it helps! Please post back if the root cause of this was some kind of DSC linked App-V 4 package :)
Rash.
