  • Artikel

Status: Resolved

Update 120314: Closing the loop on this: the hotfix is now publicly available. It may take some time for the corresponding KB to be available as well.

Update 120207: We have a private ready for testing. We're shipping this off to exisiting customers a.s.a.p., so we can get the public hotfix done after the private has been accepted. Current release timeframe is REL12-03 (March).

Update 120126: The private is nearing completion. Expect an update soon! :)

Update 120112: Engineering is now working on a private for this. Two more customers reported this. As soon as the private is available I will update this space.

Hello All, it has been some time... end of last week my colleague Marc sent me a memory dump of a problem that turns out to be a known one. The issue occurs when connection to the storage for a CSV is lost. Then. a race condition can occur where a read/write IRP is still being processed for a a device that has already been removed from the system, due to the connection problem. In such case, the machine will crash because the IRP is forwarded by the CSVfilter.sys driver. The hotfix for this is scheduled for April 2012 (HTP12-04), under KB2639032. Some details of the crash are below.
