Windows 7 experiences 100% disk busy and system compleltely unresponsive - won't even move the mouse pointer. Occurs anything from a few minutes to an hour after connecting to a VPN to which many other Windows 7 users connect with no problem. The problem sometimes clears itself in 5-30 minutes but on other occasions has carried on overnight. Disk activity will subside and then stop if I pull out the network cable.
Happens without me doing anything specific to trigger the problem.
Once the problem begins ResourceMonitor quickly falls behind and stops responding but as the problem gathers pace a typical Resource Monitor showing would be “System” with pid 4 writing about 9MB/sec to pagefile.sys, lsass.exe was reading about 8MB/sec from pagefile.sys, and other programs such as iexplorer, outlook and avp were reading substantial amounts from pagefile.sys. The physical memory was only about 50% utilised at that time.
This was happening on a laptop which had been rebuilt clean with 32 bit Windows 7 after previously working OK with Vista (if that's not a contradiction in terms).
I've just got a different brand new laptop, run it OK for a week with XP then done a clean rebuild with 64 bit Windows 7 - and immediately get the problem back again with the same symptoms. This machine has 4GB memory, 250GB disk with 200GB free - when the problem happened there was 2.5GB memory available - so why the pagefile writing?
Even when the problem isn't occurring you can see in Resource Monitor that at certain times lsass.exe is intermittently grabbing and releasing very large amounts of memory (hundreds of MB). Maybe the problem is an extreme manifestation of this behaviour?
It's driven me nuts - now I have two machines but no solution.....
