I have a document library with an event receiver (on ItemCheckedIn) to update
an xml file with the contents of this library (Kind of custom rss feed). XML
file resides in another library.
Everything works fine if I add/delete one document at a time from the
library. But if I add (and check-in) multiple files at the same time, multiple
instances of the event receiver gets fired concurrently and try to update the
xml file at the same time resulting in error: File is in use by another process.
I have already tried <Synchronization>Synchronous</Synchronization> and this.EventFiringEnabled = false/true and Thread.Sleep(1000); but all of these doesn't seem to help.
Is there any other way to do this?
