Hi there,

Sorry for the cryptic subject header. But that about summarizes my problem :-)

Environment - Windows 2000 Server. Used as WebServer. Running a Document
management system. SQL Server 2000, Index Server being used. Documents are
primarily Compound documents. Have a custom Index Filter. The documents on
the server are opened both by the Index Server Filter (for read) and by an
application DLL running in the web context that opens the document both for
reads and for writes. The application DLL primarily reads and writes custom
and document properties to the file.

The Problem - Every once in a while, some file gets locked out - the Error
corresponds to A lock violation has occurred. (0x80030021). Using Filemon,
the error is what is in the subject header. The problem is that it is not
consistent.

I have seen a sorta related bug report for XP SP2 and a fix, but it is not
the same thing
(http://support.microsoft.com/default.aspx?scid=kb;en-us;830903). It shows
the same Locking problem though...

One pattern that I have observed is that the file might have been opened by
another process (cidaemon.exe) or the same one(inetinfo.exe) a few minutes
prior to this lockup. When things are working fine, the filemon shows the
following sequence of activity
IRP_MJ_CREATE SUCCESS Options: Open Access: All

IRP_MJ_SET_INFORMATION SUCCESS Length: 5344256
IRP_MJ_SET_INFORMATION SUCCESS Length: 5344256
IRP_MJ_CLEANUP SUCCESS
IRP_MJ_CLOSE SUCCESS

But when the Not Granted situation happens, the FASTIO_UNLOCK for the Offset
2147483539 had not occured (even though the file was closed).

The files are opened using StgOpenStorage....

Any help is appreciated! This problem is so unpredictable that I am at a
loss... If you would like I can post the filemon log.

Thanks!

Er.... Anyone? Any suggestions, pretty please? Since there is a KB article
for a similar problem on XP, I am hoping it is not a completely
unknown/obscure issue for Win2000 Server... :-)

Thanks
