Kvoops on Server

Greetings,

I have a server that crashes a lot. All the kings horses and all of the kings men (IBM support) have not been able to help for almost a year. So, I have been chasing windmills of my own trying to figure out what’s wrong.

My current windmill is a process called kvoop.exe that constantly has about 20+ processes running on our server at all times. We’ve had no luck with several PMR’s trying to figure out what they are or what’s causing them… but luckily, we had a IBM server guy in for a “health check.” He explained that it is CLIENT connections that are creating the kvoop sessions and if a “drop all” was issued it would drop the kvoops. We tested it after he left and he was right.

From what I know… kvoop is used for domain indexing or indexing attachments. We are doing neither. I have checked multiple times.

Why is the client generating a kvoop session on the server? I can understand if a kvoop process starts on their computer, not the server.

I appreciate any ideas or feedback.

p.s. In case you’re wondering about my crashes. Every crash (except one) has this signature:

  • The HTTP stack crashes

  • It is caused by a url that uses “&Highlight=”

  • NSD of the fatal thread:

Subject: KVOOP is the Keyview file filters engine

It is used by the full text indexer if databases are set to index file attachments with the option “Using conversion filters on supported files”

Are you users doing lots of searches?

Subject: re: Kvoops on Server

Carl,

Yes. We are doing a ton of FT searches on the client and web (&OpenDocument&Highlight=).

But I swear… the admin and I have gone through every full text database on the server and none are set to index attachments. I didn’t just use the catalog to find the full-text indexed databases… I created my own application to catalog every database on the server.

Subject: No Databases indexing attachments

Carl,

We have 26 databases that are full-text indexed on that server. I went through each and every database and checked its properties. None of the databases are indexing attachments.

I have a big worry that some other developers have been implementing shared views. Could that have anything to do with it?

Subject: I would have to see the PMR

But as I read what you have posted, it looks to me your trying to highlight text in a document using a null?

Or is there an value for the “Highlight=”?

Subject: Hotfix…

Thanks for the reply…

The url’s have a parameter for &Highlight= (e.g. &Hightlight=myaccount or &HighLight=smith)

IBM is creating a hotfix for us (finally). My investigation has been put on hold.

Thanks for everyone’s help.
