I'm having some problems with a few servers after deploying CSA v5 in test mode. One of the boxes is a high traffic web server running W2k3 , today roughly 8 hours after installing the agent in test mode the server hung requiring a hard reset. Upon boot is hung again almost straight away. After removing CSA the server was stable once again. Other SQL boxes that CSA v5 was deployed to also experienced issues.
Has anybody had a similar experience with CSA v5 ?
The network shim is installed. ( I believe it's a Reg hack to disable it isn't it ? )
I have created a clone of the"Servers - IIS Web Servers" Group to add exceptions. I had only added 1 network access control exception by the time the system started to hang.I have also added this box to a General group I have created to allow remote management and the companies virus scanner to run. This box is also a member of "Systems -- Test Mode" and "Servers -- All Types" that have not been altered from default.
Only a handfull of CSA events were generated for this box while the agent was installed , Maybe 20 or so , none of them seem to be related to the system hangs though.
No related messages were logged in the systems event log unfortunatly.
All of the affected machines are HP Proliant servers using NIC teaming. I suspect the problem may lie with the use of the network shim.
It doesn't seem like you can create an agent kit withouth the shim in V5 , however I have been able to disable it through the registry. I've gota machine running without the shim currently , I'll see how it goes.
Unfortunatly disabling the network shim hasn't resolved the issue. It seems performance issues are eventually experienced on all of the systems running the CSA v5 Agent , i'm kinda stuck at the moment. I have a TAC case open but have yet to find an answer. Looks like I may have to try with v4.5
