FAST Crawling Error HRESULT E_FAIL has been returned from a call to a COM component.

I got an error while start crawling from my content source by FAST Crawl
the crawl log said "Error HRESULT E_FAIL has been returned from a call to a COM component."

then I found an solution from the below link which is change the impersonate value in target content source web.config

http://www.sharepointben.com/blog/Lists/Posts/Post.aspx?ID=463

then rerun the crawling and it works.

but beware of the web.config impersonate value. if your web application is needed to be set to false. it gonna be an issue with your search component.

I got an idea for around on this. Let me take time to prove it and I'll update the result.

from my recently post download SharePoint patch
I've got an failure update content database on my SharePoint server farm shown with below picture.

I searched for the solution and found some recommendation from the Microsoft websites

http://technet.microsoft.com/en-us/library/ff382638.aspx#FarmRestart

http://technet.microsoft.com/en-us/library/ff608074.aspx

then I checked the PSConfig.exe log file and found some clue why my upgrade was failed.

[OWSTIMER] [SPContentDatabaseSequence] [ERROR] [11/10/2011 2:23:08 PM]: Found a missing feature Id = [a18927ed-93e2-4dcb-be6d-56c469beb929]

[OWSTIMER] [SPContentDatabaseSequence] [ERROR] [11/10/2011 2:23:08 PM]: The feature with Id a18927ed-93e2-4dcb-be6d-56c469beb929 is referenced in the database [MYContentDatabase], but is not installed on the current farm. The missing feature may cause upgrade to fail. Please install any solution which contains the feature and restart upgrade if necessary.

the log file said, there's a missing custom feature i had deployed on MyContentDatabase. So I retracted and remove my custom solution and run this command to upgrade the content database again

psconfig -cmd upgrade -force -inplace v2v -passphrase < passphrase > -wait

the command will upgrade my content database then I redeploy my solution into the content database again.

Download and Update patch on SharePoint Farm

Microsoft has been released SharePoint 2010 patch update for a while refer to the following links.

• Microsoft Office Updates 
• Updates for SharePoint Products 

then I downloaded the SP1 and August CU updates from the above site. Service Pack1 for many products

1. Documentum Search connector SP1
2. FAST Search for SharePoint SP1
3. FAST Search for SharePoint August CU
4. Office Web Apps SP1
5. SharePoint August CU
6. SharePoint SP1
7. SharePoint Designer SP1

All of their size around ~2GB. the SharePoint August CU size is about 1GB. I though there's a lot of bug in SharePoint.
