Virtual Disk Servce Crash on Windows 2003 Issue
Recently been seeing popup errors on Windows 2003 R2 servers running Microsoft SQL 2005 running giving Virtual Disk Service errors. When looking at the event log there are Application errors showing event id 1000. In doing some research found KB949001which a hotfix for the very error.
This hotfix should only be applied to servers experiencing this issue and requires a reboot after applying. According to the article you could see several errors in the event log.
On a Windows Server 2003-based computer, Virtual Disk Service (VDS) experiences an access violation. Then, VDS crashes when the service tries to close. This issue typically occurs when VDS is running under a heavy load.
Additionally, the following events are logged in the Application log and in the System log:
Event Source: Application Error

This problem occurs because of a timing issue between two threads in VDS.
VDS maintains a list of software providers. When VDS closes, it releases the reference to software provider objects first. If a disk layout notification message arrives when some objects are freed but when the list is not freed, VDS may access an invalid software provider object. An access violation occurs when VDS accesses this list.
Maybe you’ll want to place a twitter icon to your blog. I just bookmarked the site, but I must make this by hand. Simply my $.02 🙂
