andyturpie Posted January 15, 2013 Posted January 15, 2013 Hi guys and gals, Since mid December our CC4 install seems to slowly degraded to a point now where we cannot build machines keeps failing at (installing additional packages), my connect is now showing the majority of users as unknown and its currently taking users around 5-7 mins to log in. Christmas eve, the power was shutdown for electrical work (which we were not privvy to the info), it was an SMS that alerted me from people trying to remote in. The 27th I came in to restart the servers and they shut down almost instantaniously due to the sockets that the UPS where plugged into tripped when the power was restored on Christmas eve! 3rd line and RM have been looking at this for a week and we are still no further forward. Anyone else suffer from this over sensitivity with CC4?

I HAD THIS EXACT SAME PROBLEM!! IIRC, it was something to do with the system account [it has a seemingly random name] being deleted or corrupt. If you go into RMMC, can you open the general registry settings or user properties for a specific account? 1
rad Posted January 15, 2013 Posted January 15, 2013 LOG A CALL WITH RM!! They are there to help you, log it, and escalate it if you need to. 1
X-13 Posted January 15, 2013 Posted January 15, 2013 LOG A CALL WITH RM!! They are there to help you, log it, and escalate it if you need to. From the sounds of it, he has. This looks like Andy is just asking to see if anyone knows what it is. 1

Will check this out, did you find that all these issues resolved themselves once this was done? With the slow log ins and slow mapped drive delivery, I have checked switches and they seem okay, yesterday I isolated the servers from the core switch to an edge switch and patched in a laptop, the build still failed?
andyturpie Posted January 15, 2013 Author Posted January 15, 2013 LOG A CALL WITH RM!! They are there to help you, log it, and escalate it if you need to. Hi Rad, already had RM in for a remote session, they split my call up into so many segments, with the issues vaguely overlapping and we seem to be heading in circles.

Yup. Almost instantly. IIRC that's the account used to install software. 1
Danp Posted January 15, 2013 Posted January 15, 2013 Sounds a lot like the issues we had last September, that turned out to be a borked core switch. Replaced that and since then builds have been fine. Are you fully up to date with updates? Have a look at DWN2970239 and TEC1622957 1
Oaktech Posted January 15, 2013 Posted January 15, 2013 We've had similar issues with our CC3 network. that turned out (as it so often is) to be a conspiracy of problems... a corrupt system account, inconsistent permissions on build areas and one of two trunked fibre lines between our core switch and the rest of the network that had a nicked jacket and was unstable.
andyturpie Posted January 15, 2013 Author Posted January 15, 2013 My bad and apologies, He he no need for apologies
Sylv3r Posted January 15, 2013 Posted January 15, 2013 Cannot build machines keeps failing at (installing additional packages) We had this exact issue just before christmas but none of the other issues you mention - ours had something to do with a corrupt password on the system account connected to the DB. RM 3rd line support dialled in and resolved the issue after a couple of days tinkering and going round in circles with the 1st line support team. 1
d-taylor Posted January 16, 2013 Posted January 16, 2013 We have a batch file that stops RM Service host, clears out the cache files, then starts it again. We have to run this everytime we get a powercut, and also with the odd quirk when it happens. Won't fix your issue, sounds like something much nastier, but RM Service Host isn't very resilient and I resent that I have to run this batch file each time when a vanilla network would just work. I'm sure 3rd line will get to the bottom of your issue. We have multiple DC's but if Service Host fails network is knackered. There is still no redundancy in CC4 which is just silly. Something we've also noticed is the RM Database grows over time and RMMC starts to slow (several updates addressed this but it still happens.) RM will dial in and tidy the database, this does help for a couple of years then it happens again. 1
andyturpie Posted January 17, 2013 Author Posted January 17, 2013 Hi Guys, Just like to say that RM have been absolutely brilliant and have managed to get to the bottom of the issue which was rectified in a timely and professional manner. I know that there are purists on here which don't hold RM or products in good light, but I think credit where credit is due!
d-taylor Posted January 17, 2013 Posted January 17, 2013 Below is the batch file for the FRDC on Server 2008 R2. Running this can solve many CC4 oddities that crop up: @echo off rem ******************************** rem Restarts service host and deletes cache rem ********************************** @echo on net stop /yes "RM service Host" @echo Waiting for RM service Host To Stop :loop6 @Rem Wait for 30 seconds @PING 1.1.1.1 -n 1 -w 30000 >NUL @echo Checking Service State @sc query "RM service Host" | @FIND "1 STOPPED" @If %ERRORLEVEL% NEQ 0 goto loop6 @echo Confirmed: RM service Host Service Stopped @echo Clearing service host cache @Rem Wait for 30 seconds RD /Q /S "C:\Program Files (x86)\RM\Connect\Comms\HostedProxies" RD /Q /S "C:\Program Files (x86)\RM\Connect\Comms\RemotingHost" del /Q /F "C:\ProgramData\RM\Connect\Comms\*.rmcache" del /Q /F "C:\ProgramData\RM\Connect\Comms\*.cache" del /Q /F "C:\Users\All Users\Application Data\RM\Networks\RMMC\CacheManager\*.rmcache" net start /yes "RM service Host" @echo Waiting for RM service Host To Start :loop7 @Rem Wait for 30 seconds @PING 1.1.1.1 -n 1 -w 30000 >NUL @echo Checking Service State @sc query "RM service Host" | @FIND "4 RUNNING" @If %ERRORLEVEL% NEQ 0 goto loop7 @echo Confirmed: RM service Host Started 2

Might be worthwhile dropping this in the scripts section of the forum as it maybe of value to others!

X-13 Posted January 18, 2013 Posted January 18, 2013 So... yeah. This has happened to us AGAIN. [3 times so far, about a month apart...]
andyturpie Posted January 22, 2013 Author Posted January 22, 2013 Spoke too soon, back to square one again
X-13 Posted January 22, 2013 Posted January 22, 2013 Spoke too soon, back to square one again Make sure UAC is off. Then restart the server. I was on the phone to RM yesterday getting it fixed here. Apparently, that's the problem. 1
andyturpie Posted January 22, 2013 Author Posted January 22, 2013 will give that a look at cheers! Also our replica DC had just recovered from a BSoD.... why meeeeeeeeeeeeeeeeeeeeeeeeeeee!
andyturpie Posted January 22, 2013 Author Posted January 22, 2013 Looks like our issue was DNS related, RM found out that DNS on our replica domain was listening over 3 different ranges 192.x.x.x 172.x.x.x and 10.x.x.x. This was changed to only listen on 172.x.x.x and then RMDatabase could then be reached. Shutdown Friday and restarted to find the same settings replicated back to our Domain Controller - hows our luck!

Gatt Posted January 22, 2013 Posted January 22, 2013 I always thought the best way to break CC4 was to install CC4 ? When I was working at the school, we were fortunate not to get CC4 (due to RM agreeing that my network was running smoothly and without any issues). The other schools however were not that fortunate and had endless calls about CC4 issues.. That being said, CC4 seems to be one of those products where every single install is different and whilst 3 schools in the area have issues, the other 10 wont - despite it being an almost identical set-up. Downside to my school not getting CC4 (and my subsequent falling out with a few people before I left) was that I didn't get a chance to learn it hands on -so its difficult for me to help with it or form a proper opinion of its stability, usability and other pros and cons...
andyturpie Posted January 22, 2013 Author Posted January 22, 2013 Strange that so many things can completely break CC4... It did arrive at our school with "Fragile" written all over it lol.
