Hi.
We have three 27" iMacs at work. They are the first version of the latest slim line 'sealed' design.
One has started frequently producing kernel panics.
Whilst I do use Macs and OS X my main experience is Windows so I have little experience of troubleshooting this issue.
Can anyone help.
I have included the content of one of the recent kernel panic logs.
Some background. They are all on a Windows Server 2008r2 network and domain.
They use Thursday software 'DAVE' to reliably connect to the DFS structure we use. They also all have Pathfinder installed.

Thanks for the replies and sorry for the slow response.
They are the two I suspected to be honest so I will have a close look at these two apps.
Unfortunately removing the Thursby software is going to be difficult as without it the Macs refuse to work properly on the Windows domain with DFS that we have.
They just cannot 'see' some of the folders and directories.

Try just removing the Sophos to start. I suspect that may be the culprit from personal past experiences.

I doubt it Sophos. The backtrace line lists the Thursby software as the problem.
I saw that as well, but then there is also the fact that he mentioned he has three Macs, including another identical to the affected one and only that one machine is panicking.

Has the machine in question had any hardware changes recently? For example, addition of RAM? The vast majority of kernel panics occur as a result of hardware issues, like RAM problems.
